copied!<p>I expanded the sample to create a test and... <code>parameters</code> held the correct value. What didn't work was passing the parameters to <code>actions_dispatch2.php</code>. Try passing the parameters as the second argument to <code>load(...)</code>:</p> <pre><code> wrap.load(page_to_load, "action=" + action + parameters); </code></pre> <p>Edit: Strike that, it works both ways in my test case under Safari 4.0.3 and FF 3.5. It's worth a try, but it's probably not the solution.</p> <p>We need a complete minimal test case, as what's provided will work.</p> <p>An alternative is to do away with the "parameters" attribute, which is both non-standard and and unnecessary duplication of the data in the form inputs. Extend jQuery with a method to collect parameters:</p> <pre><code>jQuery.extend(jQuery.fn, {parameters: function(type) { type = type || ''; var params = this.children('input'+type).map(function (i) { if (this.value) { return this.name + '=' + this.value; } else { return this.name; } } ); return Array.prototype.join.call(params, '&'); } }); </code></pre> <p>Then, in your onBeforeLoad handler:</p> <pre><code>var parameters = '&' + this.getTrigger().closest('form').parameters(':hidden'); </code></pre> <p>You could probably leave out the ':hidden' argument. If you wish, you could alter <code>parameters</code> to additionally take multiple types (as e.g. an array of selectors) to get the parameters from multiple input types.</p> <p>As for Firebug pointers, see:</p> <ul> <li><a href="http://www.evotech.net/blog/2007/06/introduction-to-firebug/" rel="nofollow noreferrer">Introduction To Firebug</a></li> <li><a href="http://www.webmonkey.com/tutorial/Build_Better_Pages_With_Firebug" rel="nofollow noreferrer">Build Better Pages With Firebug</a></li> <li><a href="http://www.digitalmediaminute.com/screencast/firebug-js/" rel="nofollow noreferrer">Firebug screencast</a></li> </ul>
