jquery simple implementation of the page elements when the suspension effect sample _jquery

The example of this article is about the method of the suspension effect of jquery when the page elements are simply implemented. Share to everyone for your reference, specific as follows:

One, JS Code:

<script type= "Text/javascript" >
  $.fn.smartfloat = function () {
    var position = function (element) {
      var top = element.position (). Top, pos = element.css ("position");
      $ (window). Scroll (function () {
        var scrolls = $ (this). ScrollTop ();
        if (Scrolls > top) {
          if window. XMLHttpRequest) {
            element.css ({
              position: "Fixed",
              top:0
            });
          } else {
            element.css ({
              top:scrolls
            });
          }
        else {
          element.css ({
            position:pos,
            top:top
          })
    ;}}; Return $ (a). each (function () {
      position ($ (this));
    });
  Bind
  $ ("#float"). Smartfloat ();
</script>

Second, Html Code:

<div class= "float" id= "float" style= "border:1px solid #e0e0e0; padding:10px; " >
  I was on top of the suspension zone </div>
