JS代码中使用项目路径的方法

  1. <script type="text/javascript">  
  2.     function getRootPath()   
  3.     {   
  4.      var pathName = window.location.pathname.substring(1);   
  5.      var webName = pathName == '' ? '' : pathName.substring(0, pathName.indexOf('/'));   
  6.      return window.location.protocol + '//' + window.location.host + '/'+ webName + '/';   
  7.     }   
  8.     alert (getRootPath());  
  9. </script>  
function getRealPath(){
//获取当前网址,如: http://localhost:8083/myproj/view/my.jsp
var curWwwPath=window.document.location.href;
//获取主机地址之后的目录,如: myproj/view/my.jsp
var pathName=window.document.location.pathname;
var pos=curWwwPath.indexOf(pathName);
//获取主机地址,如: http://localhost:8083
var localhostPaht=curWwwPath.substring(0,pos);
//获取带"/"的项目名,如:/myproj
var projectName=pathName.substring(0,pathName.substr(1).indexOf( '/' )+1);
var realPath=localhostPaht+projectName;
alert(realPath);
}
