//js获取项目根路径,如: http://localhost:8083/uimcardprj
function getRootPath(){
    //获取当前网址,如: http://localhost:8083/uimcardprj/share/meun.jsp
    var curWwwPath=window.document.location.href;
    //获取主机地址之后的目录,如: uimcardprj/share/meun.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:/uimcardprj
    var projectName=pathName.substring(0,pathName.substr(1).indexOf('/')+1);
    return(localhostPaht+projectName);
}

 

判断url包含某字符串:

var path = window.document.location.pathname;
if (path=="/user/do/editpassword"){
    alert("ok");
}
