<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title></title><script src="jquery-1.6.2.min.js" type="text/javascript"></script><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>
