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.
