js获取项目根路径

//js获取项目根路径，如： http://localhost:7070/mbserv
function getRootPath(){
//获取当前网址，如： http://localhost:7070/mbserv/share/meun.jsp
var curWwwPath=window.document.location.href;
//获取主机地址之后的目录，如： mbserv/share/meun.jsp
var pathName=window.document.location.pathname;
var pos=curWwwPath.indexOf(pathName);
//获取主机地址，如： http://localhost:7070
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);
}

String path = getRequest().getContextPath();
String basePath = getRequest().getScheme()+"://"+getRequest().getServerName()+":"+getRequest().getServerPort()+path+"/";

/**应用部署绝对路径*/
String sysWebPath = getRequest().getSession().getServletContext().getRealPath("");
