jquery method to control partial page refresh_jquery

The example in this article describes the method of jquery controlling partial refresh of the page. Share it with everyone for your reference. The specific analysis is as follows:

This code is very cleverly designed. It loads the content of the specified tag of the page through jQuery's load method

$('#button1').click(function() {
  var url = "http:www.your-url.com?ID=" + Math.random();
  //create random number
  setTimeout(function() {
  $("#elementName").load(url+" #elementName>*","");
  }, 1000); //wait one second to run function
});

I hope this article will be helpful to everyone’s jQuery programming.
