<!DOCTYPE html><html lang="en" xmlns="http://www.w3.org/1999/xhtml"><head><meta charset="utf-8" /><title></title><style type="text/css">* {margin: 0;padding: 0;}div.centent {float: left;text-align: center;margin: 10px;}span {display: block;margin: 2px 2px;padding: 4px 10px;background: #898989;cursor: pointer;font-size: 12px;color: white;}</style><script src="jquery-1.3.2.min.js"></script><script>$(function () {$("#add").click(function () {//单个添加var $options = $("#select1 option:selected");$options.appendTo("#select2");});$("#add_all").click(function () {//全部添加$("#select1 option").each(function () {$(this).appendTo("#select2");/*也可以写为:var p=$("#select1 option");p.appendTo("#select2");*/});});$("#remove").click(function () {//同上,只不过方向相反var $options = $("#select2 option:selected");// var $remove = $options.remove();$options.appendTo("#select1");});$("#remove_all").click(function () {//同上,只不过方向相反var p = $("#select2 option");p.appendTo("#select1");});});</script></head><body><div class="centent"><select multiple id="select1" style="width:100px;height:160px"><option value="1">选项1</option><option value="2">选项2</option><option value="3">选项3</option><option value="4">选项4</option><option value="5">选项5</option><option value="6">选项6</option></select><div><span id="add">选中添加到右边>></span><span id="add_all">全部添加到右边>;></span></div></div><div class="centent"><select multiple id="select2" style="width:100px;height:160px"></select><div><span id="remove"><<选中删除到左边</span><span id="remove_all"><<全部删除到左边</span></div></div></body></html>
