struts2项目中用Js获取URL地址参数

 

//组装一个url地址，并跳转到该地址

 

<mce:script type="text/javascript"><!--function newsubmit(){var url = document.location.href;var entId = ""if (url.indexOf("=")>0){entId = url.substring(url.indexOf("=")+1,url.length) }var string = "addQualPage.action?entId=" + entIdwindow.location.href = string}// --></mce:script> 

 

<s:submit type="button" id="newbtn" value="新增资质"  onclick="newsubmit();"  />

 

 

这里要注意一点，struts2在第一次提交时会带有一个jsessionid：

http://localhost:8080/xxx/findQualList.action;jsessionid=DC277E8D15F8D9244F92494EED690608?entId=6

 

如果只取第一个“=”，则跳转后可能出现如下问题：

http://localhost:8080/xxx/addQualPage.action?entId=DC277E8D15F8D9244F92494EED690608

 

解决方案

把url.indexOf("=")>0 修改为url.lastIndexOf("=")>0

 

完整代码如下：

<mce:script type="text/javascript"><!--function newsubmit(){var url = document.location.href;var entId = ""if (url.lastIndexOf("=")>0){entId = url.substring(url.lastIndexOf("=")+1,url.length)}var string = "addQualPage.action?entId=" + entIdwindow.location.href = string}// --></mce:script>
