JQM里面當我們更新了某些頁面標簽(如: listview, radiobuttons, checkboxes, select menus)里的數據時,必須做refresh操作.

為什么必須做refresh操作操作呢?因為JQM在做頁面渲染的時候,為了使樣式跟客戶端程序相似, 隱藏了原始的標簽然后用一些新的標簽和自定義的樣式來表現原標簽,其實新樣式的標簽已經不是原來的標簽,所以更新了數據必須做refresh操作.

各類標簽的刷新

1.Textarea fields

$('body').prepend('<textarea id="myTextArea"></textarea>');
$('#myTextArea').textinput();

2.Text input fields

$('body').prepend('<input type="text" id="myTextField" />');
$('#myTextField').textinput();

3.Buttons

$('body').append('<a  data-theme="e" id="myNewButton">testing</a>');
$('#myNewButton').button();

4.Combobox or select dropdowns

<label for="sCountry">Country:</label>
<select name="sCountry" id="sCountry">
<option value="">Where You Live:</option>
<option value="ad">Andorra</option>
<option value="ae">United Arab Emirates</option>
</select>
 
var myselect = $("#sCountry");
myselect[0].selectedIndex = 3;
myselect.selectmenu('refresh');

5.Listviews

<ul id="myList" data-role="listview" data-inset="true">
<li>Acura</li>
<li>Audi</li>
<li>BMW</li>
</ul>
 
$('#mylist').listview('refresh');

6.Slider control

<div data-role="fieldcontain">
<label for="slider-2">Input slider:</label>
<input type="range" id="slider-2" value="25" min="0" max="100" />
</div>
 
$('#slider-2').val(80).slider('refresh');

7.Toggle switch

<div data-role="fieldcontain">
<label for="toggle">Flip switch:</label>
<select name="toggle" id="toggle" data-role="slider">
<option value="off">Off</option>
<option value="on">On</option>
</select>
</div>
 
var myswitch = $("#toggle");
myswitch[0].selectedIndex = 1;
myswitch .slider("refresh");

8.Radio buttons

<div data-role="fieldcontain">
  <fieldset data-role="controlgroup" data-type="horizontal">
   <legend>Layout view:</legend>
     <input type="radio" name="radio-view" value="list" />
     <label for="radio-view-a">List</label>
     <input type="radio" name="radio-view" value="grid" />
     <label for="radio-view-b">Grid</label>
     <input type="radio" name="radio-view" value="gallery" />
     <label for="radio-view-c">Gallery</label>
  </fieldset>
</div>
 
$("input[value=grid]").attr('checked',true).checkboxradio('refresh');

9.Checkboxes

<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<legend>Agree to the terms:</legend>
<input type="checkbox" name="checkbox-1" id="checkbox-1" class="custom" />
<label for="checkbox-1">I agree</label>
</fieldset>
</div>
 
$('#checkbox-1').attr('checked',true).checkboxradio('refresh');
