js獲取項目根路徑及get參數

//js獲取項目根路徑，如： http://localhost:8083/uimcardprj

    function getRootPath(){

        //獲取當前網址，如： http://localhost:8083/uimcardprj/share/meun.jsp

        var curWwwPath=window.document.location.href;

        //獲取主機地址之後的目錄，如： uimcardprj/share/meun.jsp

        var pathName=window.document.location.pathname;

        var pos=curWwwPath.indexOf(pathName);

        //獲取主機地址，如： http://localhost:8083

        var localhostPaht=curWwwPath.substring(0,pos);

        //獲取帶"/"的項目名，如：/uimcardprj

        var projectName=pathName.substring(0,pathName.substr(1).indexOf('/')+1);

        return(localhostPaht+projectName);

    }
