jsp 获取项目名称

一：获取项目名称（如：‘cdjzzjfglmh’）

(function(){
            var contextPath="<%=request.getSession().getServletContext().getContextPath()%>";
            window.$$ = function(uri) {
                return (contextPath+"/"+uri).replace(//{2}/, '/');
            };
            window.filePath=window.uir = contextPath+"/static/portalSite";
        })();

console.log(window.$$('personal/showEvidence'));  //cdjzzjfglmh/personal/showEvidence
console.log(window.$$(URL路径);
