document.fgColor
Description
The fgColor property is expressed as a hexadecimal RGB triplet or as one of the string literals listed in "Color values". This property is the JavaScript reflection of the TEXT attribute of the BODY tag. The default value of this property is set by the user on the Colors tab of the Preferences dialog box, which is displayed by choosing General Preferences from the Options menu. You cannot set this property after the HTML source has been through layout.
If you express the color as a hexadecimal RGB triplet, you must use the format rrggbb. For example, the hexadecimal RGB values for salmon are red=FA, green=80, and blue=72, so the RGB triplet for salmon is "FA8072." You can override the value set in the fgColor property in either of the following ways:
document.fgColor="aqua"The following example sets the color of the foreground text to aqua using a hexadecimal triplet:
document.fgColor="00FFFF"
fixed
Method. Causes a string to be displayed in fixed-pitch font as if it were in a TT tag.
Syntax
stringName.fixed()
Parameters
stringName is any string or a property of an existing object.
Method of
string
Description
Use the fixed method with the write or writeln methods to format and display a string in a document. In LiveWire, use the write function to display the string.
Examples
The following example uses the fixed method to change the formatting of a string:
var worldString="Hello, world"
document.write(worldString.fixed())
The previous example produces the same output as the following HTML:
<TT>Hello, world</TT>
In LiveWire, you can generate this HTML by calling the write function instead of using document.write.
floor
Method. Returns the greatest integer less than or equal to a number.
Syntax
Math.floor(number)
Parameters
number is any numeric expression or a property of an existing object.
Method of
Math
Examples
The following function returns the floor value of the variable x:
function getFloor(x) {
return Math.floor(x)
}
If you pass getFloor the value 45.95, it returns 45; if you pass it the value -45.95, it returns -46.

ceil method
focus
Method. Gives focus to the specified object.
Syntax
1. passwordName.focus()
2. selectName.focus()
3. textName.focus()
4. textareaName.focus()
Parameters
passwordName is either the value of the NAME attribute of a password object or an element in the elements array.
selectName is either the value of the NAME attribute of a select object or an element in the elements array.
textName is either the value of the NAME attribute of a text object or an element in the elements array.
textareaName is either the value of the NAME attribute of a textarea object or an element in the elements array.
Method of
password object, select object, text object, textarea object
Description
Use the focus method to navigate to a specific form element and give it focus. You can then either programmatically enter a value in the element or let the user enter a value.
Examples
In the following example, the checkPassword function confirms that a user has entered a valid password. If the password is not valid, the focus method returns focus to the password object and the select method highlights it so the user can re-enter the password.
function checkPassword(userPass) {
if (badPassword) {
alert("Please enter your password again.")
userPass.focus()
userPass.select()
}
}
This example assumes that the password object is defined as
<INPUT TYPE="password" NAME="userPass">

fontcolor
Method. Causes a string to be displayed in the specified color as if it were in a FONT COLOR=color tag.
Syntax
stringName.fontcolor(color)
Parameters
stringName is any string or a property of an existing object.
color is a string or a property of an existing object, expressing the color as a hexadecimal RGB triplet or as one of the string literals listed in "Color values".
Description
Use the fontcolor method with the write or writeln methods to format and display a string in a document. In LiveWire, use the write function to display the string.
If you express color as a hexadecimal RGB triplet, you must use the format rrggbb. For example, the hexadecimal RGB values for salmon are red=FA, green=80, and blue=72, so the RGB triplet for salmon is "FA8072."
The fontcolor method overrides a value set in the fgColor property.
Examples
The following example uses the fontcolor method to change the color of a string:
var worldString="Hello, world"
document.write(worldString.fontcolor("maroon") +
" is maroon in this line")
document.write("<P>" + worldString.fontcolor("salmon") +
" is salmon in this line")
document.write("<P>" + worldString.fontcolor("red") +
" is red in this line")
document.write("<P>" + worldString.fontcolor("8000") +
" is maroon in hexadecimal in this line")
document.write("<P>" + worldString.fontcolor("FA8072") +
" is salmon in hexadecimal in this line")
document.write("<P>" + worldString.fontcolor("FF00") +
" is red in hexadecimal in this line")
The previous example produces the same output as the following HTML:
<FONT COLOR="maroon">Hello, world</FONT> is maroon in this line
<P><FONT COLOR="salmon">Hello, world</FONT> is salmon in this line
<P><FONT COLOR="red">Hello, world</FONT> is red in this line
<FONT COLOR="8000">Hello, world</FONT> is maroon in hexadecimal in this line
<P><FONT COLOR="FA8072">Hello, world</FONT> is salmon in hexadecimal in this line
<P><FONT COLOR="FF00">Hello, world</FONT> is red in hexadecimal in this line
In LiveWire, you can generate this HTML by calling the write function instead of using document.write.
fontsize
Method. Causes a string to be displayed in the specified font size as if it were in a FONTSIZE=size tag.
Syntax
stringName.fontsize(size)
Parameters
stringName is any string or a property of an existing object.
size is an integer between one and seven, a string representing a signed integer between one and seven, or a property of an existing object.
Method of
string
Description
Use the fontsize method with the write or writeln methods to format and display a string in a document. In LiveWire, use the write function to display the string.
When you specify size as an integer, you set the size of stringName to one of the seven defined sizes. When you specify size as a string such as "-2," you adjust the font size of stringName relative to the size set in the BASEFONT tag.
Examples
The following example uses string methods to change the size of a string:
var worldString="Hello, world"
document.write(worldString.small())
document.write("<P>" + worldString.big())
document.write("<P>" + worldString.fontsize(7))
The previous example produces the same output as the following HTML:
<SMALL>Hello, world</SMALL>
<P><BIG>Hello, world</BIG>
<P><FONTSIZE=7>Hello, world</FONTSIZE>
In LiveWire, you can generate this HTML by calling the write function instead of using document.write.

form
Object. Lets users input text and make choices from form objects such as checkboxes, radio buttons, and selection lists. You can also use a form to post data to a server.
HTML syntax
To define a form, use standard HTML syntax with the addition of the onSubmit event handler:
<FORM
NAME="formName"
TARGET="windowName"
ACTION="serverURL"
METHOD=GET | POST
ENCTYPE="encodingType"
[onSubmit="handlerText"]>
</FORM>
HTML attributes
NAME="formName" specifies the name of the form object.
TARGET="windowName" specifies the window that form responses go to. When you submit a form with a TARGET attribute, server responses are displayed in the specified window instead of the window that contains the form. windowName can be an existing window; it can be a frame name specified in a FRAMESET tag; or it can be one of the literal frame names _top, _parent, _self, or _blank; it cannot be a JavaScript expression (for example, it cannot be parent.frameName or windowName.frameName). You can access this value using the target property.
ACTION="serverURL" specifies the URL of the server to which form field input information is sent. This attribute can specify a CGI or LiveWire application on the server; it can also be a mailto: URL if the form is to be mailed. See the location object for a description of the URL components. You can access this value using the action property.
METHOD=GET | POST specifies how information is sent to the server specified by ACTION. GET (the default) appends the input information to the URL, which on most receiving systems becomes the value of the environment variable QUERY_STRING. POST sends the input information in a data body, which is available on stdin with the data length set in the environment variable CONTENT_LENGTH. If the METHOD attribute has the value "POST," then the ENCTYPE attribute typically has the value "application/x-www-form-urlencoded." You can access this value using the method property.
ENCTYPE="encodingType" specifies the MIME encoding of the data sent: "application/x-www-form-urlencoded" (the default) or "multipart/form-data." Use "multipart/form-data" if the form contains a file upload element (INPUT TYPE="file"). If the METHOD attribute has the value "POST," then the ENCTYPE attribute typically has the value "application/x-www-form-urlencoded." You can access this value using the encoding property.
Syntax
To use a form object's properties and methods:
1. formName.propertyName
2. formName.methodName(parameters)
3. forms[index].propertyName
4. forms[index].methodName(parameters)
Parameters
formName is the value of the NAME attribute of a form object.
index is an integer representing a form object.
propertyName is one of the properties listed below.
methodName is one of the methods listed below.
Property of
document
Description
Each form in a document is a distinct object.
You can reference a form's elements in your code by using the element's name (from the NAME attribute) or the elements array. The elements array contains an entry for each element (such as a checkbox, radio, or text object) in a form.
The forms array
You can reference the forms in your code by using the forms array (you can also use the form name). This array contains an entry for each form object (FORM tag) in a document in source order. For example, if a document contains three forms, these forms are reflected as document.forms[0], document.forms[1], and document.forms[2].
To use the forms array:
1. document.forms[index]
2. document.forms.length
index is an integer representing a form in a document.
To obtain the number of forms in a document, use the length property: document.forms.length.
You can also refer to a form's elements by using the forms array. For example, you would refer to a text object named quantity in the second form as document.forms[1].quantity. You would refer to the value property of this text object as document.forms[1].quantity.value.
Elements in the forms array are read-only. For example, the statement document.forms[0]="music" has no effect.
The value of each element in the forms array is <object nameAttribute>, where nameAttribute is the NAME attribute of the form.
Properties
The form object has the following properties:
The following objects are also properties of the form object:
The forms array has one property, length, that reflects the number of forms in the document.
Methods
submit method
Examples
Example 1: named form. The following example creates a form called form1 that contains text fields for first name and last name. The form also contains two buttons that change the names to all uppercase or all lowercase. The function setCase shows how to refer to the form by its name.
<HTML>
<HEAD>
<TITLE>Form object example</TITLE>
</HEAD>
<SCRIPT>
function setCase (caseSpec){
if (caseSpec == "upper") {
document.form1.firstName.value=document.form1.firstName.value.toUpperCase()
document.form1.lastName.value=document.form1.lastName.value.toUpperCase()}
else {
document.form1.firstName.value=document.form1.firstName.value.toLowerCase()
document.form1.lastName.value=document.form1.lastName.value.toLowerCase()}
}
</SCRIPT>
<BODY>
<FORM NAME="form1">
<B>First name:</B>
<INPUT TYPE="text" NAME="firstName" SIZE=20>
<BR><B>Last name:</B>
<INPUT TYPE="text" NAME="lastName" SIZE=20>
<P><INPUT TYPE="button" VALUE="Names to uppercase" NAME="upperButton"
onClick="setCase('upper')">
<INPUT TYPE="button" VALUE="Names to lowercase" NAME="lowerButton"
onClick="setCase('lower')">
</FORM>
</BODY>
</HTML>
Example 2: forms array. The onLoad event handler in the following example displays the name of the first form in an Alert dialog box.
<BODY onLoad="alert('You are looking at the ' + document.forms[0] + ' form!')">
If the form name is musicType, the alert displays the following message:
You are looking at the <object musicType> form!
Example 3: onSubmit event handler. The following example shows an onSubmit event handler that determines whether to submit a form. The form contains one text object where the user enters three characters. The onSubmit event handler calls a function, checkData, that returns true if the number of characters is three; otherwise, it returns false. Notice that the form's onSubmit event handler, not the submit button's onClick event handler, calls the checkData function. Also, the onSubmit event handler contains a return statement that returns the value obtained with the function call.
<HTML>
<HEAD>
<TITLE>Form object/onSubmit event handler example</TITLE>
<TITLE>Form object example</TITLE>
</HEAD>
<SCRIPT>
var dataOK=false
function checkData (){
if (document.form1.threeChar.value.length == 3) {
return true}
else {
alert("Enter exactly three characters. " + document.form1.threeChar.value +
" is not valid.")
return false}
}
</SCRIPT>
<BODY>
<FORM NAME="form1" onSubmit="return checkData()">
<B>Enter 3 characters:</B>
<INPUT TYPE="text" NAME="threeChar" SIZE=3>
<P><INPUT TYPE="submit" VALUE="Done" NAME="submit1"
onClick="document.form1.threeChar.value=document.form1.threeChar.value.toUpperCase()">
</FORM>
</BODY>
</HTML>
Example 4: submit method. The following example is similar to the previous one, except it submits the form using the submit method instead of a submit object. The form's onSubmit event handler does not prevent the form from being submitted. The form uses a button's onClick event handler to call the checkData function. If the value is valid, the checkData function submits the form by calling the form's submit method.
<HTML>
<HEAD>
<TITLE>Form object/submit method example</TITLE>

frame
Object. A window that can display multiple, independently scrollable frames on a single screen, each with its own distinct URL. Frames can point to different URLs and be targeted by other URLs, all within the same screen. A series of frames makes up a page.
HTML syntax
To define a frame object, use standard HTML syntax. The onLoad and onUnload event handlers are specified in the FRAMESET tag but are actually event handlers for the window object:
<FRAMESET
ROWS="rowHeightList"
COLS="columnWidthList"
[onLoad="handlerText"]
[onUnload="handlerText"]>
[<FRAME SRC="locationOrURL" NAME="frameName">]
</FRAMESET>
HTML attributes
ROWS="rowHeightList" is a comma-separated list of values specifying the row-height of the frame. An optional suffix defines the units. Default units are pixels.
COLS="columnWidthList" is a comma-separated list of values specifying the column-width of the frame. An optional suffix defines the units. Default units are pixels.
<FRAME> defines a frame.
SRC="locationOrURL" specifies the URL of the document to be displayed in the frame. The URL cannot include an anchor name; for example <FRAME SRC="doc2.html#colors" NAME="frame2"> is invalid. See the location object for a description of the URL components.
NAME="frameName" specifies a name to be used as a target of hyperlink jumps.
Syntax
To use a frame object's properties:
1. [windowReference.]frameName.propertyName
2. [windowReference.]frames[index].propertyName
3. window.propertyName
4. self.propertyName
5. parent.propertyName
Parameters
windowReference is a variable windowVar from a window definition (see the window object), or one of the synonyms top or parent.
frameName is the value of the NAME attribute in the FRAME tag of a frame object.
index is an integer representing a frame object.
propertyName is one of the properties listed below.
Property of
The frame object is a property of the window object.
The frames array is a property of both the frame object and window object.
Description
The FRAMESET tag is used in an HTML document whose sole purpose is to define the layout of frames that make up a page. Each frame is a window object.
If a FRAME tag contains SRC and NAME attributes, you can refer to that frame from a sibling frame by using parent.frameName or parent.frames[index]. For example, if the fourth frame in a set has NAME="homeFrame," sibling frames can refer to that frame using parent.homeFrame or parent.frames[3].
The self and window properties are synonyms for the current frame, and you can optionally use them to refer to the current frame. You can use these properties to make your code more readable. See the properties listed below for examples.
The top and parent properties are also synonyms that can be used in place of the frame name. top refers to the top-most window that contains frames or nested framesets, and parent refers to the window containing the current frameset. See the top and parent properties.
The frames array
You can reference the frame objects in your code by using the frames array. This array contains an entry for each child frame (FRAME tag) in a window containing a FRAMESET tag in source order. For example, if a window contains three child frames, these frames are reflected as parent.frames[0], parent.frames[1], and parent.frames[2].
To use the frames array:
1. [frameReference.]frames[index]
2. [frameReference.]frames.length
3. [windowReference.]frames[index]
4. [windowReference.]frames.length
frameReference is a valid way of referring to a frame, as described in the frame object.
windowReference is a variable windowVar from a window definition (see the window object), or one of the synonyms top or parent.
index is an integer representing a frame in a parent window.
To obtain the number of child frames in a window or frame, use the length property:
[windowReference.].frames.length
[frameReference.].frames.length
Elements in the frames array are read-only. For example, the statement windowReference.frames[0]="frame1" has no effect.
The value of each element in the frames array is <object nameAttribute>, where nameAttribute is the NAME attribute of the frame.
Properties
The frame object has the following properties:
The frames array has one property, length, that reflects the number of child frames in a frameset document.
Methods
Event handlers
None. The onLoad and onUnload event handlers are specified in the FRAMESET tag but are actually event handlers for the window object.
Examples
The following example creates two windows, each with four frames. In the first window, the first frame contains pushbuttons that change the background colors of the frames in both windows. framset1.html, which defines the frames for the first window, contains the following code:

Method of
history
Description
The go method navigates to the location in the history list determined by the argument that you specify. You can interactively display the history list by choosing History from the Window menu. Up to ten items in the history list are also displayed on the Go menu.
The delta argument is a positive or negative integer. If delta is greater than zero, the go method loads the URL that is that number of entries forward in the history list; otherwise, it loads the URL that is that number of entries backward in the history list. If delta is zero, Navigator reloads the current page.
The location argument is a string. Use location to load the nearest history entry whose URL contains location as a substring. The location to URL matching is case-insensitive. Each section of a URL contains different information. See the location object for a description of the URL components.
Examples
The following button navigates to the nearest history entry that contains the string "home.netscape.com":
<P><INPUT TYPE="button" VALUE="Go"
onClick="history.go('home.netscape.com')">
The following button navigates to the URL that is three entries backward in the history list:
<P><INPUT TYPE="button" VALUE="Go"
onClick="history.go(-3)">
