我必须在页脚中使用滚动功能，其中数据动态存储在按钮中并且滚动应该隐藏然后我们滚动它再次显示并且所有数据和滚动应该在页脚中动态加载只有窗口屏幕不应该改变只有页脚会改变滚动时间

在jQuery中： -

 function callXMLConnection() {  

        $.support.cors = true;
           $.ajax({
                type: "GET",
                url: "url.html",
                contentType: "text/xml",
                dataType: "xml",
                data: "",
                cache:false,
                processData:false,
                crossDomain:true,
                success: processSuccess,

            });

      }


      function processSuccess(data) {

             $(data).find("category").each(function () {

             var id = $(this).find('id').text();
             var title = $(this).find('title').text();
             var scripts = "<a href='#' data-role='button' data-theme='b' data-inline='true'>"+title+"</a>"                
            $("#menu_button1")
             .append(scripts)
             .trigger('create');
         });
      }
   $(document).unbind('ready').bind('ready', function () {
     $("#menu_button1").scroll(function () {
     // if ($("#menu_button1").scrollLeft(300) == $(document).width() - $("#menu_button1").width()) 
     if ($("#menu_button1").scrollHeight - $("#menu_button1").scrollTop() == $("#menu_button1").outerHeight())
     {
       callXMLConnection(); 
   }
});

     });

在 html5 中：-

<div data-role="footer" data-position="fixed" id="scroll_menu" style="overflow: scroll;">
              <div class="menu" id="menu_button1" ></div>
</div>

最后我得到了这些的答案

在 HTML5 中：-

 <div data-role="page" data-theme="b" id="jqm-home">    
      <div data-role="footer" data-position="fixed" data-theme="c">        
           <div  class="categories" id="cat">                
              <ul id="cat_list" class="cat_list_class"></ul>               
           </div>
      </div>    
</div>

在jQuery中： -

 var step = 1;
 var current = 0;
 var maximum = 0;
 var visible = 2;
 var speed = 500;
 var liSize = 120;
 var height = 60;    
 var ulSize = liSize * maximum;
 var divSize = liSize * visible;

 $(document).unbind('pageinit').bind('pageinit', function () {    
      callMenuConnection(); 
       $('.categories').css("width", "auto").css("height", height+"px").css("visibility", "visible").css("overflow", "hidden").css("position", "relative");
       $(".categories ul a").css("list-style","none").css("display","inline");
       $(".categories ul").css("width", ulSize+"px").css("left", -(current * liSize)).css("position", "absolute").css("white-space","nowrap").css("margin","0px").css("padding","5px");      
  });

 $(document).unbind('click').bind('click', function () {
        scroll();
 });
   function callMenuConnection() {  
       $.support.cors = true;
       $.ajax({
            type: "GET",
            url: "one.html",
            contentType: "text/xml",
            dataType: "xml",
            data: "",
            cache:false,
            processData:false,
            crossDomain:true,
            success: processSuccess,
            error: processError
        }); 
  }
      var scripts ="";     
  function processSuccess(data) {
         $(data).find("category").each(function () {     
         var id = $(this).find('id').text();
         var title = $(this).find('title').text();
          scripts = scripts+'<a  class="ids_cat" data-role="button" data-transition="slide"  data-inline="true" >' +title+ '</a>';
        });
        $('#cat_list').append(scripts);
        $('#cat_list').trigger('create');
         maximum = $(".categories ul a").size();
  }

     function processError(data)
       {
           alert("error");
       }

 function scroll(){ 
 $(".categories").swipeleft(function(event){
  if(current + step < 0 || current + step > maximum - visible) {return; }
else {
    current = current + step;
    $('.categories ul').animate({left: -(liSize * current)}, speed, null);
}
return false;
});

  $(".categories").swiperight(function(event){
    if(current - step < 0 || current - step > maximum - visible) {return; }
        else {
      current = current - step;
       $('.categories ul').animate({left: -(liSize * current)}, speed, null);
    }
   return false;
   });         
 }
