假设在页脚部分我想要 50 个数据，这些数据来自 ajax 调用，当我们触摸数据时，所有数据都应该是直线，它也会移动，通过鼠标它也会移动，就像它应该滚动一样，请帮助我获取数据但它不是滚动的，数据不是直线的

在 HTML5 中：-

 <div data-role="footer" data-position="fixed" id="footer_ids" onmousedown="startReverseSlider(event)" ontouchstart="startReverseSlider(event)">
              <div class="menu_cat_ids" id="menu_button_ids" ></div>
         </div> 
         <style>
            #footer_ids{
                    position: fixed;
                    width:100%;
                    overflow-x:auto;
                    bottom: 1px;
                    z-index: 10;
                    text-align: center;
                    height: 5%;
            }
          </style>

在jQuery中： -

$(document).unbind('pageinit').bind('pageinit', function () {

          callMenuConnection(); 

      });

function callMenuConnection() {  
        $.support.cors = true;
           $.ajax({
                type: "GET",
                url: "one.html",
                contentType: "text/xml",
                dataType: "xml",
                data: "",
                cache:false,
                processData:false,
                crossDomain:true,
                success: function (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_button_ids").append(scripts).trigger('create'); 
        });
      }

            }); 
      }


 function startReverseSlider(event){
theElement=event.currentTarget;
startX = endX = getCurrentPositionX(event);
startY = endY = getCurrentPositionY(event);
mx = getCurrentPositionX(event) - $('#menu_button_ids').offset().left;
document.addEventListener("mousemove",moveReverseSlider,true);
document.addEventListener("mouseup",dropReverseSlider,true);
document.addEventListener("touchmove",moveReverseSlider,true);
document.addEventListener("touchend",dropReverseSlider,true);
//event.stopPropagation();
event.preventDefault();
}        


       function dropReverseSlider(event)
       {    
     document.removeEventListener("mouseup",dropReverseSlider,true);
     document.removeEventListener("mousemove",moveReverseSlider,true);
     document.removeEventListener("touchend",dropReverseSlider,true);
     document.removeEventListener("touchmove",moveReverseSlider,true);
     //event.stopPropagation();
     }

  function moveReverseSlider(event)
   {    
   endX = getCurrentPositionX(event);
   endY = getCurrentPositionY(event);
   var clientX = getCurrentPositionX(event) - mx;
   if(clientX+sliderLeft < -w+vx-sliderLeft){
     } else if (clientX > sliderLeft) {
       } else {
      $('#menu_button_ids').css('left',(clientX-sliderLeft)+'px');
       var X =$('#menu_button_ids').offset().left - sliderLeft;
       var P=-X*(rs)/(w);
          if (P > rs-ts) {
          P = rs - ts;
           }
}

}

在 HTML 5 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>

现在在 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;
});         
}
