document.fgColor
Implemented in
Navigator 2.0
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:
Examples
The following example sets the color of the foreground text to aqua using a string literal:
document.fgColor="aqua"
The following example sets the color of the foreground text to aqua using a hexadecimal triplet:
document.fgColor="00FFFF"

stringName.fixed()
Implemented in
Navigator 2.0
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"
The previous example produces the same output as the following HTML:
document.write(worldString.fixed())<TT>Hello, world</TT>
In LiveWire, you can generate this HTML by calling the write function instead of using document.write.
Math.floor(number)
Implemented in
Navigator 2.0
Examples
The following function returns the floor value of the variable x:
function getFloor(x) {
If you pass getFloor the value 45.95, it returns 45; if you pass it the value -45.95, it returns -46.
return Math.floor(x)

1. passwordName.focus()
2. selectName.focus()
3. textName.focus()
4. textareaName.focus()
5. frameReference.focus()
6. windowReference.focus()
windowReference is a valid way of referring to a window, as described in the window object.
Method of
Frame object, Password object, Select object, Text object, Textarea object, window object
Implemented in
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.
The focus method gives focus to a window or frame. Giving focus brings a window forward in most windowing systems.
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) {
This example assumes that the Password object is defined as
if (badPassword) {
alert("Please enter your password again.")
userPass.focus()
userPass.select()
}
}<INPUT TYPE="password" NAME="userPass">

stringName.fontcolor(color)
Implemented in
Navigator 2.0
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"
The previous example produces the same output as the following HTML:
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")<FONT COLOR="maroon">Hello, world</FONT> is maroon in this line
In LiveWire, you can generate this HTML by calling the write function instead of using
<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 linedocument.write.
stringName.fontsize(size)
Implemented in
Navigator 2.0
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"
The previous example produces the same output as the following HTML:
document.write(worldString.small())
document.write("<P>" + worldString.big())
document.write("<P>" + worldString.fontsize(7))<SMALL>Hello, world</SMALL>
In LiveWire, you can generate this HTML by calling the write function instead of using
<P><BIG>Hello, world</BIG>
<P><FONTSIZE=7>Hello, world</FONTSIZE>document.write.

3. forms[index].propertyName
4. forms[index].methodName(parameters)
Implemented in
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]
index is an integer representing a form in a document.
To obtain the number of forms in a document, use the length property:
2. document.forms.lengthdocument.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 the following properties:

Methods
Event handlers
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>
Example 2: forms array. The onLoad event handler in the following example displays the name of the first form in an Alert dialog box.
<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><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>
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.

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.
frameReference is a valid way of referring to a frame.
errorHandler is the keyword null, the name of an error-handling function, or a variable or property that contains null or a valid function reference.
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.
Implemented in
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.
To create an onBlur or onFocus event handler for a frame, you must set the onblur or onfocus property and specify it in all lowercase (you cannot specify it in HTML).
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]
frameReference is a valid way of referring to a frame.
windowReference is a variable windowVar from a window definition (see the window object), or one of the synonyms top or parent.
2. [frameReference.]frames.length
3. [windowReference.]frames[index]
4. [windowReference.]frames.length
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
Elements in the frames array are read-only. For example, the statement windowReference
[frameReference.].frames.length.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.

document object, window object
functionTarget = new Function ([arg1, arg2, ... argn], functionBody)
window.onerror.
arg1, arg2, ... argn are string arguments to be used by the function as formal argument names.
functionBody is a string specifying the JavaScript code to be compiled as the function body.
var setBGColor = new Function("document.bgColor='antiquewhite'")
To call the Function object, you can specify the variable name as if it were a function. The following code executes the function specified by the setBGColor variable:
var colorChoice="antiquewhite"You can assign the function to an event handler in either of the following ways:
if (colorChoice=="antiquewhite") {setBGColor()}
1. document.form1.colorButton.onclick=setBGColorCreating the variable setBGColor shown above is similar to declaring the following function:
2. <INPUT NAME="colorButton" TYPE="button"
VALUE="Change background color"
onClick="setBGColor()">
function setBGColor() {
document.bgColor='antiquewhite'
}
Assigning a function to a variable is similar to declaring a function, but they have differences:
var setBGColor = new Function("..."), setBGColor is a variable for which the current value is a reference to the function created with new Function().
function setBGColor() {...}, setBGColor is not a variable, it is the name of a function.var multFun = new Function("x", "y", "return x * y")
The string arguments "x" and "y" are formal argument names that are used in the function body, "return x * y".
The following code shows several ways to call the function multFun:
var theAnswer = multFun(7,6)You cannot call the function multFun in an event handler property, because these properties cannot take arguments. For example, you cannot call the function multFun by setting a button's onclick property as follows:
document.write("15*2 = " + multFun(15,2))
<INPUT NAME="operand1" TYPE="text" VALUE="5" SIZE=5>
<INPUT NAME="operand2" TYPE="text" VALUE="6" SIZE=5>
<INPUT NAME="result" TYPE="text" VALUE="" SIZE=10>
<INPUT NAME="buttonM" TYPE="button" VALUE="Multiply"
onClick="document.form1.result.value=
multFun(document.form1.operand1.value,
document.form1.operand2.value)">
document.form1.button1.onclick=multFun(5,10)
window.onfocus = new Function("document.bgColor='antiquewhite'")
Once you have a reference to a function object, you can use it like a function and it will convert from an object to a function:
window.onfocus()Event handlers do not take arguments, so you cannot declare any arguments in the Function() constructor for an event handler.

history.go(delta | "location")
Implemented in
Navigator 2.0
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"
The following button navigates to the URL that is three entries backward in the history list:
