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 = {

Example Usage

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.

Example Code

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

Customize Browsers To Reject

Run Demo

In this example pretty much every browser should be rejected.

Example Code

        $('#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;

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

Example Code

        $('#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', // Paragraph 2
                closeMessage: 'Close this window at your own demise!' // Message below close window link
            }); // Customized Text

            return false;

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']

Example Code

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

            return false;

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.

Example Code

        $('#demo5').click(function() {
                reject: { all: true }, // Reject all renderers for demo
                display: ['flock','safari','opera'], // Displays only custom "Flock" browser, safari and opera.
                browserInfo: {
                    flock: { // Specifies browser name and image name (browser_flock.gif)
                        text: 'Flock 2+', // Text Link
                        url: 'http://flock.com/' // URL To link to

            return false;

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.

Example Code

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

            return false;

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.

Example Code

        $('#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>' // Display refresh link

            return false;
