當我們使用Ajax或者javascript動態在頁面上添加元素后，如添加select控件的option元素，添加ul的li元素。添加之后我們會發現，它們顯示的樣式不是jQuery Mobile的炫酷樣式了，而變成了很丑陋的元素樣式。如下圖所示：
代碼如下：
- <script>
- function myFunction() {
- var ul = document.getElementById("myul");
- var li1 = "<li data-role=\"fieldcontain\">信息2</li>";
- var li2 = "<li data-role=\"fieldcontain\">信息3</li>";
- ul.innerHTML += li1;
- ul.innerHTML += li2;
- }
- </script>
- <!-- listview測試 -->
- <ul data-role="listview" data-inset="true" id="myul">
- <li data-role="list-divider">信息列表</li>
- <li data-role="fieldcontain">信息1</li>
- </ul>
可以看到，jQuery Mobile並沒有對於新添加的元素進行渲染。這種情況下就需要對元素的樣式進行刷新。
刷新代碼如下：
- <script>
- function myFunction() {
- var ul = document.getElementById("myul");
- var li1 = "<li data-role=\"fieldcontain\">信息2</li>";
- var li2 = "<li data-role=\"fieldcontain\">信息3</li>";
- ul.innerHTML += li1;
- ul.innerHTML += li2;
- //刷新jQuery Mobile樣式
- $('#myul').listview('refresh');
- }
- </script>
其實最重要的一句刷新代碼是：$('#myul').listview('refresh');
刷新后的效果如下圖所示：
注意：在使用js或者jQuery獲取控件（例如：button、checkbox、radiobutton等）的值時，也是需要先刷新，否則無法獲取到最新的值。
下面列出常用的標簽的refresh操作，其他的可以舉一反三。
1. Listview的refresh操作:
$('#mylistid').listview('refresh');
2. select menu的refresh操作:
var myselect = $("#myselect");
myselect[0].selectedIndex = 2;
myselect.selectmenu("refresh");
3. Checkboxes的refresh操作:
$("#mycheckboxid").attr("checked",true).checkboxradio("refresh");
4. Radio buttons的refresh操作:
$("#myradioid").attr("checked",true).checkboxradio("refresh");
