Use getJSON () to asynchronously request the server to return data in json format. getjsonjson

We can use the getJSON () method of jquery to request the server to return json format data:

Js Code:

Function test () {$. getJSON ("JsonServlet", function (result) {alert (result. name );});}

Server-side servlet response:

@ Override protected void doPost (HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {String person = "{\" name \ ": \" zhangsan \ ", \" sex \": \ "man \", \ "age \": \ "23 \"} "; resp. getWriter (). print (person );}

Note: Both json Data Attribute names and struct values must be double quotation marks.
