  1. POIE9 - SCRIPT5009: "jQuery" is undefined
    text
    copied!<p>the following code runs into the error <em>SCRIPT5009: "jQuery" is undefined</em> in IE9 (maybe also in older IE versions):</p> <pre><code>var $tx; if (window.jQuery) { $tx = jQuery; if( jQuery().jquery.replace(".", "") &lt; 17.1 ) { addjQuery(); } } else { addjQuery(); } function addjQuery() { document.write('&lt;script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"&gt;&lt;\/script&gt;'); document.write('&lt;script type="text/javascript"&gt;$tx = jQuery.noConflict();&lt;\/script&gt;'); } document.write('&lt;script src="workingScript.js"&gt;&lt;\/script&gt;'); </code></pre> <p>I solved it! It's working fine this way:</p> <pre><code>var $tx; if (window.jQuery) { $tx = jQuery; if( jQuery().jquery.replace(".", "") &lt; 17.1 ) { addjQuery(); } } else { addjQuery(); } function addjQuery() { loadScript("http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js", function(){ $tx = jQuery.noConflict(true); }); } document.write('&lt;script src="workingScript.js"&gt;&lt;\/script&gt;'); function loadScript(url, callback){ var script = document.createElement("script") script.type = "text/javascript"; if (script.readyState){ //IE script.onreadystatechange = function(){ if (script.readyState == "loaded" || script.readyState == "complete"){ script.onreadystatechange = null; callback(); } }; } else { //Others script.onload = function(){ callback(); }; } script.src = url; document.getElementsByTagName("head")[0].appendChild(script); } </code></pre> <p>workingScript.js:</p> <pre><code>(function ($) { // some code here })($tx); </code></pre> <p>The error occours here <em>"$tx = jQuery.noConflict();"</em> if <code>addjQuery</code> function is called. If the website already uses the current jQuery version, erverythings works fine.</p> <p>Does anyone have an idea how to solve this?</p>
