Attach Demo effect Http://demo.jb51.net/js/2015/jquery-dtlb

The effect is not very good, and then we look at the waterfall flow of the implementation of ideas and JS control dynamically loaded code

The following code is mainly about loading events that control the scroll bar dropdown.

The code below shows that you can write your actions, whether loading pictures or loading record data.

Don't forget to quote the jquery class library.

 $ (window). Scroll (function () {
  var scrolltop = $ (this). ScrollTop ();
  var scrollheight = $ (document). Height ();
  var WindowHeight = $ (this). Height ();
  if (scrolltop + windowheight = = scrollheight) {

  //Here is the event triggered by the scroll bar to the bottom, where the data to be loaded is written, or the action to pull the scroll bar is

//var page = number ($ ("#redgiftNextPage"). attr (' currentpage ')) + 1;
Redgiftlist (page);
$ ("#redgiftNextPage"). attr (' currentpage ', page + 1);

  }
 });

Analytical:

To determine the scroll bar to the bottom, you need to use the DOM's three property values, namely ScrollTop, ClientHeight, ScrollHeight.
ScrollTop is the scroll distance of the scroll bar on the y-axis.
ClientHeight is the height of the content viewable area.
ScrollHeight adds an overflow (scrolling) distance to the height of the content viewable area.
From the introduction of this three attributes can be seen, the scroll bar to the bottom of the condition is scrolltop + clientheight = = ScrollHeight. (compatible with different browsers).
