jQuery Mobile動態刷新頁面樣式

當咱們使用Ajax或者javascript動態在頁面上添加元素後，如添加select控件的option元素，添加ul的li元素。添加以後咱們會發現，它們顯示的樣式不是jQuery Mobile的炫酷樣式了，而變成了很醜陋的元素樣式。以下圖所示：

 

代碼以下：

 1         <script>
 2             function myFunction() {
 3                 var ul = document.getElementById("myul");
 4                 var li1 = "<li data-role=\"fieldcontain\">信息2</li>";
 5                 var li2 = "<li data-role=\"fieldcontain\">信息3</li>";
 6                 ul.innerHTML += li1;
 7                 ul.innerHTML += li2;
 8             }
 9         </script>
10 
11         <!-- listview測試 -->
12          <ul data-role="listview" data-inset="true" id="myul">
13                  <li data-role="list-divider">信息列表</li>
14                  <li data-role="fieldcontain">信息1</li>
15          </ul>

能夠看到，jQuery Mobile並無對於新添加的元素進行渲染。這種狀況下就須要對元素的樣式進行刷新。

刷新代碼以下：

 1         <script>
 2             function myFunction() {
 3                 var ul = document.getElementById("myul");
 4                 var li1 = "<li data-role=\"fieldcontain\">信息2</li>";
 5                 var li2 = "<li data-role=\"fieldcontain\">信息3</li>";
 6                 ul.innerHTML += li1;
 7                 ul.innerHTML += li2;
 8                 
 9                 //刷新jQuery Mobile樣式
10                 $('#myul').listview('refresh');
11             }
12         </script>

其實最重要的一句刷新代碼是：$('#myul').listview('refresh');

刷新後的效果以下圖所示：

 

注意：在使用js或者jQuery獲取控件（例如：button、checkbox、radiobutton等）的值時，也是須要先刷新，不然沒法獲取到最新的值。

下面列出經常使用的標籤的refresh操做，其餘的能夠觸類旁通。
1.  Listview的refresh操做:
$('#mylistid').listview('refresh');

2. select menu的refresh操做:
var myselect = $("#myselect");
myselect[0].selectedIndex = 2;
myselect.selectmenu("refresh");

3. Checkboxes的refresh操做:
$("#mycheckboxid").attr("checked",true).checkboxradio("refresh");

4. Radio buttons的refresh操做:
$("#myradioid").attr("checked",true).checkboxradio("refresh");
