This might be happening if you are loading jQuery and other scripts in the footer/end of the body. What you can do is queue the calls to jQuery and then execute them once jQuery is loaded. Colin has a very good script for doing so here: <a href="http://blog.colin-gourlay.com/blog/2012/02/safely-using-ready-before-including-jquery/" rel="nofollow">http://blog.colin-gourlay.com/blog/2012/02/safely-using-ready-before-including-jquery/</a> . </p> https://legacy.forums.gravityhelp.com/topic/jquery-not-defined-empty-jquery-function-in-wp_head#post-51185 Fri, 02 Mar 2012 19:16:14 +0000 rpetersnmt 51185@https://legacy.forums.gravityhelp.com/ <p>Trying to bump this up again....I've circled back here, still trying to solve this issue. Turns out that Gravity was putting this empty function in before wp_head(), where I was previously including jQuery. I've remedied that part now, but when an AJAX form (that's key...the AJAX bit, "regular" forms now no longer trip an "undefined" error) is submitted with validation errors...I still get the nagging "jQuery is undefined" error...but the form still seems to perform correctly. Scratching my head here....anyone have an idea what's going on or how to fix it?</p> <p>Try submitting one of these forms with not data entered...you'll see the errors in Firebug and should see that jQuery is present just two lines ahead of the offending tags....</p> <p><a href="http://www.missouladowntown.com/add-property/" rel="nofollow">http://www.missouladowntown.com/add-property/</a><br /> <a href="http://www.missouladowntown.com/add-member/" rel="nofollow">http://www.missouladowntown.com/add-member/</a> </p> https://legacy.forums.gravityhelp.com/topic/jquery-not-defined-empty-jquery-function-in-wp_head#post-47476 Thu, 26 Jan 2012 20:12:05 +0000 rpetersnmt 47476@https://legacy.forums.gravityhelp.com/ <p>Hey guys...I'm running into an odd JS error:</p> <p>Error: jQuery is not defined<br /> Source File: <a href="http://www.missouladowntown.com/add-property/" rel="nofollow">http://www.missouladowntown.com/add-property/</a><br /> Line: 46</p> <p>Also here:<br /> <a href="http://www.missouladowntown.com/contact/" rel="nofollow">http://www.missouladowntown.com/contact/</a><br /> <a href="http://www.missouladowntown.com/add-member/" rel="nofollow">http://www.missouladowntown.com/add-member/</a></p> <p>But not, say, here (no GF form):<br /> <a href="http://www.missouladowntown.com/dine/" rel="nofollow">http://www.missouladowntown.com/dine/</a></p> <p>This seems to be appearing on any page within our site that has an embedded GF Form....here's the rendered source code (empty function) that's triggering there firebug/JS error:</p> <p> '&lt;script&gt;<br /> jQuery(function(){<br /> });<br /> &lt;/script&gt;'</p> <p>Any thoughts as to why this function is printing out and/or why it is empty?</p> <p>Thanks in advance. </p>
