    text
    copied!<p>I'm trying to remove special characters that could appear within my Google Analytics tags, as the special characters seem to be causing script errors in some versions of IE. I have this function:</p> <pre><code> function removeSplChars(inStr) { inStr = inStr.replace(/[^a-zA-Z0-9 ]/g, ""); return inStr; } </code></pre> <p>and there is the GA code that currently works:</p> <pre><code> &lt;script type="text/javascript"&gt; var _gaq = _gaq || []; _gaq.push(['_setAccount', '&lt;c:out value="${profileId}"/&gt;']); &lt;c:choose&gt; &lt;c:when test="${(lastCmdName eq 'CategoryDisplay') or (lastCmdName eq 'ProductDisplay')}" &gt; _gaq.push(['_setCustomVar', 2, // This custom var is set to slot #2. '&lt;c:choose&gt;&lt;c:when test="${WCParam.source eq 'search'}"&gt;Search&lt;/c:when&gt;&lt;c:otherwise&gt;&lt;c:out value="${topCat}" /&gt;&lt;/c:otherwise&gt;&lt;/c:choose&gt;', // The top-level name for your online content categories. '&lt;c:choose&gt;&lt;c:when test="${WCParam.source eq 'search'}"&gt;Search &lt;c:out value="${WCParam.searchTerm}" /&gt;&lt;/c:when&gt;&lt;c:otherwise&gt;&lt;c:out value="${topCat}" /&gt;|&lt;c:out value="${subCatA}" /&gt;|&lt;c:out value="${subCatB}" /&gt;|&lt;c:out value="${subCatC}" /&gt;&lt;/c:otherwise&gt;&lt;/c:choose&gt;', // Records value of breadcrumb name 3 // Sets the scope to page-level. ]); &lt;/c:when&gt; &lt;c:otherwise&gt; &lt;/c:otherwise&gt; &lt;/c:choose&gt; _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); &lt;/script&gt; </code></pre> <p>But when I place that function within the code, I still see special characters coming up in the Chrome Debugger. For example, when I pull up a page that has a product called "Matt's" it shows up as Matt&#039;s. What I want is Matts. We have other product names with ampersands and other special characters, so I just want to allow A-z and numbers (caps/no caps are OK)</p> <p>Any advice would be appreciated. I have looked at the following posts on SO but so far not found anything that helps me make this work:</p> <p><a href="https://stackoverflow.com/questions/3004487/how-to-handle-special-characters-in-javascript">How to handle (&#174; &#180; &#169; &#191; &#161; &#176; &#192; ) special characters in javascript?</a><br/> <a href="https://stackoverflow.com/questions/4374822/javascript-regexp-remove-all-special-characters">javascript regexp remove all special characters</a><br/> <a href="https://stackoverflow.com/questions/6555182/remove-all-special-characters-except-space-from-a-string-using-javascript">Remove all special characters except space from a string using JavaScript</a></p> <p>I am new to JSP and JavaScript so I am sure I'm not placing the code in the right place, or maybe I need to add something else on the page? I have tried placing the removeSplChars function within () or adding a ; and no luck. Unfortunately, I have to learn this on the job so I have to focus on completing the tasks I've been given rather than taking the time to truly understand the logic/syntax of the language. </p>
