    text
    copied!<p>When I have the following inside the same HTML document it seems to work:</p> <pre><code>&lt;script type="text/javascript"&gt; datasets[0] = { "buildnames": { label: "buildnames", data: ["test2-a1", "test2-a2", "test2-a3", "test2-a4","test2-a5", "test2-a6"] } }; function doSomething() { var i = 0; for (var j = 0; j &lt; datasets.length; j++){ $.each(datasets[j], function(key, val) { val.color = i; ++i; }); var choiceContainer = $("#choices"); //var testkey = new RegExp("cover"); $.each(datasets[j], function(key, val) { if (key.indexOf("failed") &gt; -1 || key.indexOf("cover") &gt; -1) { choiceContainer.append('&lt;br /&gt;&lt;input type="checkbox" name="' + key + '" checked="checked" id="id' + key + '"&gt;' + '&lt;label for="id' + key + '"&gt;' + val.label + '&lt;/label&gt;'); } }); } } &lt;/script&gt; </code></pre> <p>But when I'm exporting this to a separate JavaScript file and then importing it and call the function like this</p> <pre><code>&lt;script type="text/javascript" language="Javascript" src="root/include/graph_1.js"&gt;&lt;/script&gt; &lt;a href="javascript:doSomething()"&gt;doSomething&lt;/a&gt; </code></pre> <p>I get the following error: '<code>$</code>' is undefined and points at "<code>$.each(..</code>" So why can't I use this function is I "export" all JavaScript code in an HTML document to another separate JavaScript file?</p> <p><em><strong></em>**<em>*</em>**<em>*</em>**<em>*</em>**</strong><em>edit</em><strong><em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>*</strong></p> <p>I tried the tips below and changed the order</p> <p>@idbentley I did what you said and changed the order of those 2 so it is</p> <pre><code> &lt;script language="javascript" type="text/javascript" src="root/include/jquery.js"&gt;&lt;/script&gt; &lt;script language="javascript" type="text/javascript" src="root/include/jquery.flot.js"&gt;&lt;/script&gt; &lt;script language="javascript" type="text/javascript" src="root/include/jquery.flot.crosshair.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" language="Javascript" src="root/include/graph_1.js"&gt;&lt;/script&gt; </code></pre> <p>But now I get another error "Exception thrown and not caught" Anyone know what this error means?</p>
