ajax动态增加html节点时，jqm样式未加载出来，须实现refresh操作
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");
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 href="" 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">Flipswitch:</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"/>
<labelfor="radio-view-a">List</label>
<input type="radio"name="radio-view"value="grid"/>
<labelfor="radio-view-b">Grid</label>
<input type="radio"name="radio-view"value="gallery"/>
<labelfor="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');
