How to create a jQuery function to return a bool?
<p>How can I create a jQuery function like </p>

<pre><code>$.MyFunction(/*optional parameter*/)?
</code></pre>

<p>which will return a bool?</p>

<p><strong>note:</strong></p>

<p>I've tried this:  </p>

<pre><code>jQuery.fn.isValidRequest = function (options) {

    return true;
}

// I'm contending with Prototype, so I have to use this    
jQuery(document).ready(function ($) {    

    // and jQuery 1.2.6, supplied by the client - long story
    $('a').livequery('click', function () {

        alert($.isValidRequest("blah"));
        return false;
    });
});
</code></pre>

<p>but it crashes on the alert() with </p>

<pre><code>Microsoft JScript runtime error: Object doesn't support this property or method
</code></pre>

<p><strong>This is what worked in the end:</strong></p>

<pre><code>jQuery.isValidRequest = function (options) {

    return true;
}
</code></pre>
