getJSON() asynchronously requests the server to return json format data (graphic tutorial)

Below I will bring you an implementation of using getJSON() to asynchronously request the server to return json format data. Let me share it with you now and give it as a reference for everyone.

We can use jquery's getJSON() method 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 character values ​​are required It’s double quotation marks

. I compiled the above for everyone. I hope it will be helpful to everyone in the future.
