jQuery：实现两个<select>控件的互移操作
一、直接上代码
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <meta charset="utf-8" /> 5 <title>index</title> 6 </head> 7 <body> 8 <div> 9 <select id="leftSelector" multiple="multiple" name="SmsListOnLeft" style="height:100px; width:50px"> 10 <option value="0">0</option> 11 <option value="1">1</option> 12 <option value="2">2</option> 13 <option value="3">3</option> 14 <option value="4">4</option> 15 <option value="5">5</option> 16 </select> 17 18 <span style="top: 30px; position: fixed;"> 19 <input type="button" value="<<" id="btnLeft" /> 20 <input type="button" value=">>" id="btnRight" /> 21 </span> 22 23 <select id="rightSelector" multiple="multiple" name="SmsListOnRight" style="height:100px; width:50px; margin-left:80px"> 24 <option value="6">A</option> 25 <option value="7">B</option> 26 <option value="8">C</option> 27 <option value="9">D</option> 28 <option value="10">E</option> 29 </select> 30 31 </div> 32 33 <br> 34 35 <input type="button" onclick="selectAll()" id="btnSelectAll" value="selectAll" /> 36 37 <script src="js/jquery-2.1.4.js"></script> 38 <script> 39 $("#btnRight").click(function () { 40 //数据option选中的数据集合赋值给变量vSelect 41 var vSelect = $("#leftSelector option:selected"); 42 //克隆数据添加到 rightSelector 中 43 vSelect.clone().appendTo("#rightSelector"); 44 //同时移除 leftSelector 中的 option 45 vSelect.remove(); 46 }); 47 48 //right move 49 $("#btnLeft").click(function () { 50 var vSelect = $("#rightSelector option:selected"); 51 vSelect.clone().appendTo("#leftSelector"); 52 vSelect.remove(); 53 }); 54 55 function selectAll() { 56 var lst1 = window.document.getElementById("rightSelector"); 57 var length = lst1.options.length; 58 for (var i = 0; i < length; i++) { 59 var v = lst1.options[i].value; //option内的value 60 var t = lst1.options[i].text; //显示的文本 61 alert(v + ":" + t); 62 } 63 } 64 </script> 65 66 </body> 67 </html>
