01.页面代码:
<%
String basePath = request.getScheme()
+ "://"
+ request.getServerName()
+ ":"
+ request.getServerPort()
+ request.getContextPath();
%>
02.脚本代码:
function getBasePath(){
//获取当前网址,如:http://localhost:8080/prj/.../xxx.jsp
var fullPath=window.document.location.href;
//获取主机地址之后的目录,如:/prj/.../xxx.jsp
var pathName=window.document.location.pathname;
//获取主机地址,如:http://localhost:8080
var pos=fullPath.indexOf(pathName);
var hostPath=fullPath.substring(0,pos);
//获取带"/"的项目名,如:/prj
var projectName=pathName.substring(0,pathName.substr(1).indexOf('/')+1);
return(hostPath+projectName);
}
