本文实例讲述了JQuery实现带排序功能的权限选择。分享给大家供大家参考。具体实现方法如下：

<style type="text/css">
select{width:100px;height:100px;float:left;margin:10px;}
#main{float:left;width:100px;text-align:center;margin:10px;}
#main input{width:100px;}
</style>
<script type="text/javascript">
var myJson = [{ "id": "1", "Name": "刘德华", "Age": "52" },
 { "id": "2", "Name": "文章", "Age": "26" },
 {"id":"3","Name":"孙红雷","Age":"40"},
 { "id": "4", "Name": "葛优", "Age": "58"}];
 $(function () {
  var $leftSel = $("#leftSel");
  for (var i = 0; i < myJson.length; i++) {
   var $option = $("<option sortID='" + myJson[i].id + "' value='" + myJson[i].Name + "'>" +
   myJson[i].id + "," + myJson[i].Name + "</option>");
   $option.appendTo($leftSel);
  }
  $("#btnMoveLeft").click(function () {
   var $selOptions = $("#leftSel option:selected");
   $selOptions.appendTo($("#rightSel")).attr("selected", false);
  });
  $("#btnMoveLeftAll").click(function () {
   var $allLeftOptions = $("#leftSel option");
   $allLeftOptions.appendTo($("#rightSel")).attr("selected", false);
  });
  $("#btnMoveRight").click(function () {
   var $selOptions = $("#rightSel option:selected");
   $selOptions.appendTo($leftSel).attr("selected", false);
  });
  $("#btnMoveRightAll").click(function () {
   var $allRightOptions = $("#rightSel option");
   $allRightOptions.appendTo($leftSel).attr("selected", false);
  });
  $("#btnMoveLeftSort").click(function () {
   //把右边列表的内容添加到左边，并按sortID属性进行排序
   $("#rightSel option").appendTo($("#leftSel"));
   var $sortArray = $("#leftSel option").sort(function (prev, next) {
    var prevSortID = parseInt(prev.sortID);
    var nextSortID = parseInt(next.sortID);
    if (prevSortID > nextSortID) {
 return 1;   //交换位置
    }
    else {
 return -1;
    }
   });
   $("#leftSel").empty().append($sortArray);
  });
});
</script>
</head>
<body>
<select id="leftSel" multiple="multiple">
</select>
<div id="main">
<input id="btnMoveLeft" type="button" value="-->" />
<input id="btnMoveLeftAll" type="button" value="==>" />
<input id="btnMoveRight" type="button" value="<--" />
<input id="btnMoveRightAll" type="button" value="<==" />
<input id="btnMoveLeftSort" type="button" value="<--Sort" />
</div>
<select id="rightSel" multiple="multiple">
</select>
</body>
</html>
