Introduction
This article will teach about BOM (Browser Object Model), JavaScript Navigator, and HistoryObject in JavaScript. In my previous article, I explained BOM object methods and properties. If you want to read the article, click the link.
The BOM (Browser model objects) are:
- Windows Object
- Navigator Object
- Location Object
- Screen Object
- Storage Object
The Navigator Object in JavaScript
The JavaScript navigator object is used for browser detection. It can get browser information such as version and browser type.
The Navigator object has two features,
Methods in Navigator Object in JavaScript
The following table contains the methods of the JavaScript Navigator object in JavaScript.
- Methods
- Description
- javaEnabled()
It Specifies whether or not Java is enabled in the browser.
- taintEnabled()
It Specifies whether the data field is enabled in the browser.
Examples of Navigator object Methods in JavaScript
We can see the examples of location methods one by one,
The javaEnabled() Method in JavaScript
The JavaScript Navigator javaEnabled () method returns a Boolean value indicating whether Java is enabled in a browser. If Java is enabled in the browser, it returns true else; it returns false.
Syntax
navigator.javaEnabled ()
Example
The following programs illustrate the navigator javaEnabled () method in HTML.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Navigator object Methods</title>
</head>
<body>
<h2>The javaEnabled () Method</h2>
<button ondblclick="java()">Click_To_Check</button>
<p id="javaEnabled"></p>
<script type="text/javascript">
function java() {
var ch ="Java Enabled is : " + navigator.javaEnabled();
document.getElementById("javaEnabled").innerHTML = ch;
}
</script>
</body>
</html>
Output
![BOM Windows Navigator Object In JavaScript]()
The taintEnabled() Method in JavaScript
The JavaScript Navigator taintEnable() method was best avoided in Javascript version 1.5 and was later removed to prevent future run-time errors. It returns a false Boolean value, specifying whether the browser enables the data-tainting feature.
Syntax
navigator.taintEnabled ()
Example
The following programs illustrate the navigator taintEnabled () method in HTML.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Navigator object Methods</title>
</head>
<body>
<h2>The taintEnabled () Method</h2>
<input type="button"value="Click to check" onClick="taint()">
<script language="JavaScript">
function taint() {
var temp = navigator.taintEnabled();
alert(window.navigator.taintEnabled());
}
</script>
</body>
</html>
Output
![BOM Windows Navigator Object In JavaScript]()
