本文实例讲述了jQuery实现的自动加载页面功能。分享给大家供大家参考,具体如下:

demo.html:

<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>---------------</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>阅谁问君诵,水落清香浮</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>阅谁问君诵,水落清香浮</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>阅谁问君诵,水落清香浮</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>阅谁问君诵,水落清香浮</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>阅谁问君诵,水落清香浮</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>阅谁问君诵,水落清香浮</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>阅谁问君诵,水落清香浮</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>阅谁问君诵,水落清香浮</p></li>
<li style="opacity:0;-moz-opacity: 0;filter: alpha(opacity=0);"><p>+++++++++++++++</p></li>

scrollpagination.js:

(function( $ ){
 $.fn.scrollPagination = function(options) {
    var opts = $.extend($.fn.scrollPagination.defaults, options);
    var target = opts.scrollTarget;
    if (target == null){
      target = obj;
    }
    opts.scrollTarget = target;
    return this.each(function() {
     $.fn.scrollPagination.init($(this), opts);
    });
 };
 $.fn.stopScrollPagination = function(){
   return this.each(function() {
    $(this).attr('scrollPagination', 'disabled');
   });
 };
 $.fn.scrollPagination.loadContent = function(obj, opts){
   var target = opts.scrollTarget;
   var mayLoadContent = $(target).scrollTop()+opts.heightOffset >= $(document).height() - $(target).height();
   if (mayLoadContent){
     if (opts.beforeLoad != null){
      opts.beforeLoad();
     }
     $(obj).children().attr('rel', 'loaded');
     $.ajax({
       type: 'POST',
       url: opts.contentPage,
       data: opts.contentData,
       success: function(data){
        $(obj).append(data);
        var objectsRendered = $(obj).children('[rel!=loaded]');
        if (opts.afterLoad != null){
          opts.afterLoad(objectsRendered);
        }
       },
       dataType: 'html'
     });
   }
 };
 $.fn.scrollPagination.init = function(obj, opts){
   var target = opts.scrollTarget;
   $(obj).attr('scrollPagination', 'enabled');
   $(target).scroll(function(event){
    if ($(obj).attr('scrollPagination') == 'enabled'){
      $.fn.scrollPagination.loadContent(obj, opts);
    }
    else {
      event.stopPropagation();
    }
   });
   $.fn.scrollPagination.loadContent(obj, opts);
 };
 $.fn.scrollPagination.defaults = {
     'contentPage' : null,
     'contentData' : {},
     'beforeLoad': null,
     'afterLoad': null ,
     'scrollTarget': null,
     'heightOffset': 0
 };
})( jQuery );
