when a URL comes up, such as: Http://localhost:8080/pro/demo/hello.jsp? Name=john, on the hello.jsp page, we can get the value of name like this:


<%
String path = Request.getcontextpath ();
String basepath = request.getscheme () + "://" +request.getservername () + ":" +request.getserverport () +path+ "/";
String name = Request.getparameter ("name");//Use request to get
%>


It is then displayed in <body>hello:<%=name%></body>.

It can also be obtained directly in the body with ${}, because when Jstl is used, the URL request parameter is placed in the implied object param. So it can be written like this:


<body>hello:${param.name}</body>  
Based on this logic, the same approach can be used when using jquery, such as:
$ (function () {
Alert (${param.name});
});
