我只想使用html/css和javascript.所以请库尔告诉我我该如何解决这个问题...我正在重拍我的任务..假设我单击一个按钮/链接/图像等，它将打开https://tools.aaa.com/gdrp/coiga/showsurvey.do?surveyCode=7189&keyCode=000038167&gId=#pf:CONTACT_ID#现在我要在浏览器处理打开上述链接时调用某些javascript函数，该函数会在处理链接中搜索关键代码(如果是)找到用(window.location.replace(linkurl +``?transaction =''+ KeyCode + linktext);)替换过程链接...)...否则它将显示键码值并显示具有无效键码值的链接.表示我想更改html中的innerhtml值...
有问题或评论吗?

首先，更改函数开头的位置将使其执行方式降低-不确定.不会以这种方式工作.您应该重新考虑要实现的逻辑.
这是一个JQuery插件，您可以用来解析和处理url字符串: https://github.com/allmarkedup/jQuery-URL-Parser/blob/master/README.md [
First of all, changing the location at the very beginning of the function will drop it''s execution - in an undefined way. Won''t work this way. You should reconsider the logic you want to implement.
