Then request the data to be returned successfully and render to the page and then add 1 pages

This is also the basic need to prevent duplicate submissions.
You set a variable as a state lock, such as is_post = 0 pull-up request data 1, at this time pull no longer make a request, and so a request data completely back, and then set 0 on the line.

You need to throttle/debounce . Searched an article for you: Http://www.css88.com/archives ...

Depending on your situation, Lodash/underscore has a ready-made method to use.

Stand a flag, haha.

As an example,

var loading = false;nextPage(1);function nextPage(page) {  if (loading) return;  loading = true;  $.ajax({    // ....    success: function() {      loading = false;    }  })}

One is a state lock, as the upstairs says

There's another one called JS function throttling, go search
