一、直接上代碼

<!DOCTYPE html><html><head> <meta charset="utf-8" /> <title>index</title></head><body> <div> <select id="leftSelector" multiple="multiple" name="SmsListOnLeft" style="height:100px; width:50px"> <option value="0">0</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> </select> <span style="top: 30px; position: fixed;"> <input type="button" value="<<" id="btnLeft" /> <input type="button" value=">>" id="btnRight" /> </span> <select id="rightSelector" multiple="multiple" name="SmsListOnRight" style="height:100px; width:50px; margin-left:80px"> <option value="6">A</option> <option value="7">B</option> <option value="8">C</option> <option value="9">D</option> <option value="10">E</option> </select> </div> <br> <input type="button" onclick="selectAll()" id="btnSelectAll" value="selectAll" /> <script src="js/jquery-2.1.4.js"></script> <script> $("#btnRight").click(function () { //數據option選中的數據集合賦值給變量vSelect var vSelect = $("#leftSelector option:selected"); //克隆數據添加到 rightSelector 中 vSelect.clone().appendTo("#rightSelector"); //同時移除 leftSelector 中的 option vSelect.remove(); }); //right move $("#btnLeft").click(function () { var vSelect = $("#rightSelector option:selected"); vSelect.clone().appendTo("#leftSelector"); vSelect.remove(); }); function selectAll() { var lst1 = window.document.getElementById("rightSelector"); var length = lst1.options.length; for (var i = 0; i < length; i++) { var v = lst1.options[i].value; //option內的value var t = lst1.options[i].text; //顯示的文本 alert(v + ":" + t); } } </script></body></html>
