#main{float:left;width:100px;text-align:center;margin:10px;}

<script type="text/javascript">
var myJson = [{ "id": "1", "Name": "刘德华", "Age": "52" },
 { "id": "2", "Name": "文章", "Age": "26" },

 $(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>
