当我们使用Ajax或者javascript动态在页面上添加元素后,如添加select控件的option元素,添加ul的li元素。添加之后我们会发现,它们显示的样式不是jQuery Mobile的炫酷样式了,而变成了很丑陋的元素样式。如下图所示:

代码如下:

[html] view plaincopyprint?
  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测试 --> 
  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
        <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测试 -->         <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并没有对于新添加的元素进行渲染。这种情况下就需要对元素的样式进行刷新。

刷新代码如下:

[html] view plaincopyprint?
  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样式 
  10.         $(‘#myul‘).listview(‘refresh‘); 
  11.     } 
  12. </script
        <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样式                $(‘#myul‘).listview(‘refresh‘);            }        </script>

其实最重要的一句刷新代码是:$(‘#myul‘).listview(‘refresh‘);

刷新后的效果如下图所示:

 

注意:在使用js或者jQuery获取控件(例如:button、checkbox、radiobutton等)的值时,也是需要先刷新,否则无法获取到最新的值。

下面列出常用的标签的refresh操作,其他的可以举一反三。 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");
