JavaScript删除特殊字符串不起作用 [英] JavaScript Remove special characters string not working

问题描述

我正在尝试删除可能出现在我的Google Analytics代码中的特殊字符，因为特殊字符似乎在某些版本的IE中导致脚本错误。我有这个功能：

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:

                function removeSplChars(inStr) {
                inStr = inStr.replace(/[^a-zA-Z0-9 ]/g, "");
                return inStr;
                }

并且目前有GA代码可用：

and there is the GA code that currently works:

                <script type="text/javascript">
                var _gaq = _gaq || [];
                _gaq.push(['_setAccount', '<c:out value="${profileId}"/>']);
                <c:choose>
                <c:when test="${(lastCmdName eq 'CategoryDisplay') or (lastCmdName eq 'ProductDisplay')}" >
                _gaq.push(['_setCustomVar',
                2, // This custom var is set to slot #2.
                '<c:choose><c:when test="${WCParam.source eq 'search'}">Search</c:when><c:otherwise><c:out value="${topCat}" /></c:otherwise></c:choose>', // The top-level name for your online content categories.
                '<c:choose><c:when test="${WCParam.source eq 'search'}">Search <c:out value="${WCParam.searchTerm}" /></c:when><c:otherwise><c:out value="${topCat}" />|<c:out value="${subCatA}" />|<c:out value="${subCatB}" />|<c:out value="${subCatC}" /></c:otherwise></c:choose>', // Records value of breadcrumb name
                3 // Sets the scope to page-level.
                ]); 
                </c:when>
                <c:otherwise>
                </c:otherwise>
                </c:choose>
                 _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);
                })();
                </script>

但是当我在代码中放置该功能时，我仍然会看到Chrome调试器中出现特殊字符。例如，当我拉出一个名为Matt's的产品页面时，它显示为Matt's。我想要的是马特。我们有其他产品名称，带有&符号和其他特殊字符，所以我只想允许A-z和数字（大写/没有上限可以）

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'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)

任何建议都将不胜感激。我已经在SO上查看了以下帖子，但到目前为止还没有找到任何可以帮助我完成这项工作的帖子：

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:

如何在javascript中处理（®'¿¡¡À）特殊字符？

javascript regexp删除所有特殊字符

使用JavaScript删除除字符串空格外的所有特殊字符

我是JSP和JavaScript的新手，所以我确信我没有将代码放在正确的位置，或者我可能需要在页面上添加其他内容？我尝试将removeSplChars函数放在（）中或添加;没有运气不幸的是，我必须在工作中学习这一点，所以我必须专注于完成我给予的任务，而不是花时间真正理解语言的逻辑/语法。

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.

推荐答案

问题不在于函数本身，它来自其他地方。证明： http://jsfiddle.net/wDaCw/

The problem is not the function itself, it comes from somewhere else. Proof: http://jsfiddle.net/wDaCw/
