js 获取项目根目录

//js获取项目根路径，如： http://localhost:8080/ems function getRootPath() {
//获取当前网址，如： http://localhost:8080/ems/Pages/Basic/Person.jsp var curWwwPath = window.document.location.href;
//获取主机地址之后的目录，如： /ems/Pages/Basic/Person.jsp
var pathName = window.document.location.pathname;
var pos = curWwwPath.indexOf(pathName);
//获取主机地址，如： http://localhost:8080 var localhostPath = curWwwPath.substring(0, pos);
//获取带"/"的项目名，如：/ems
var projectName = pathName.substring(0, pathName.substr(1).indexOf('/') + 1);
return(localhostPath + projectName);
}
