获取项目路径js
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);
//得到了 http://localhost:8083/myproj
var realPath=localhostPaht+projectName;
alert(realPath);
