The object is called "reject", and can be invoked once the document is ready ($.reject() or jQuery.reject()). The first parameter contains all the options and configurations for the plugin.

Default Options

Here are the default options for the first parameter of the reject object. You only need to specify those which you wish to override.

options = {

	reject : {
		all: false, // Covers Everything (Nothing blocked)
		msie: 6 // Covers MSIE <= 6 (Blocked by default)

Example Usage

Demo #1: Default Settings

Run Demo

If nothing happened when you ran this demo, that is because you are not using IE6!
By default (no settings specified) the reject function only rejects IE5 and IE6.

$('#demo1').click(function() {
	$.reject(); // Default Settings
	return false;

Demo #2: Customize Browsers To Reject

Run Demo

In this example pretty much every browser should be rejected.

$('#demo2').click(function() {
		reject: {
			safari: true, // Apple Safari
			chrome: true, // Google Chrome
			firefox: true, // Mozilla Firefox
			msie: true, // Microsoft Internet Explorer
			opera: true, // Opera
			konqueror: true, // Konqueror (Linux)
			unknown: true // Everything else
	}); // Customized Browsers

	return false;

Demo #3: Customize Popup Text

Run Demo

In this demo we use customized text in the popup window. This demo uses the following properties:
header, paragraph1, paragraph2, closeMessage
See Also closeLink

$('#demo3').click(function() {
		reject: { all: true }, // Reject all renderers for demo
		header: 'Your browser is not supported here', // Header Text
		paragraph1: 'You are currently using an unsupported browser', // Paragraph 1
		paragraph2: 'Please install one of the many optional browsers below to proceed',
		closeMessage: 'Close this window at your own demise!' // Message below close window link
	}); // Customized Text

	return false;

Demo #4: Customize Browsers To Suggest

Run Demo

Using the display option, you can define which browsers to suggest, and the order in which to suggest them.
GCF is supported, but only displayed for IE users by default.

Default: ['firefox','chrome','msie','safari','opera','gcf']

$('#demo4').click(function() {
		reject: { all: true }, // Reject all renderers for demo
		display: ['firefox','chrome','opera'] // Displays only firefox, chrome, and opera

	return false;

Demo #5: Customize Your Own Browser Suggestion

Run Demo

You can even add a customized browser to the list, and display it in any order you want.

Note: To add your own icon, you need to create a 'browser_{browserName}.gif'
file and place it in your imagePath directory with the other images.
Image Dimensions: 100x100

$('#demo5').click(function() {
		reject: { all: true }, // Reject all renderers for demo
		// Displays only custom "Konqueror" browser, firefox and opera.
		display: ['konqueror','firefox','opera'],
		browserInfo: {
			konqueror: { // Specifies browser name and image name (browser_konqueror.gif)
				text: 'Konqueror', // Text Link
				url: 'http://konqueror.kde.org/' // URL To link to

	return false;

Demo #6: Display Once Per Session

Run Demo

By using the closeCookie option, you can make the window only appear once per session.
After it pops up the first time, this demo will not popup again until next browser session.

Note: This requires the ability to close the window. If close is false the cookie will never be set.

$('#demo6').click(function() {
		reject: { all: true }, // Reject all renderers for demo
		closeCookie: true // Set cookie to remmember close for this session

	return false;

Demo #7: Disable ability to close window

Run Demo

The close option allows you to hide the closeLink or closeMessage elements from displaying.
This prevents the user from closing the window. If you use this on a onLoad event, the user will never be able to use your site.

Note: Testing this demo will require you to refresh the page to close out the popup window.

$('#demo7').click(function() {
		reject: { all: true }, // Reject all renderers for demo
		close: false, // Prevent closing of window
		paragraph1: 'You will not be able to close this window', // Warning about closing
		paragraph2: 'To exit, you must '+
		'<a href="javascript:window.location=window.location.pathname;">refresh the page</a>'

	return false;

Demo #8: Customize by Browser

Run Demo

This example uses the beforeReject callback to change options by browser.
In chrome, only FireFox and Opera options will be displayed. iPhone/iPad displays no browser options

$('#demo8').click(function() {
		reject: { all: true }, // Reject all renderers for demo
		beforeReject: function() {
			if ($.browser.name === 'chrome') {
				this.display = ['firefox','opera'];
			if ($.os.name === 'iphone' || $.os.name === 'ipad') {
				this.browserShow = false;
				this.paragraph2 = '';

	return false;
