三个前提:
1、每个form必须设置method和action属性
2、每个form必须有页面范围内唯一的id标识
3、每个form必须有一个label标签,通过设置它的for属性来匹配元素的id
<form method="post" action="demoform.asp"> <label for="fname">First name:</label> <input type="text" name="fname" id="fname"> </form>
1、隐藏label内容:
<form method="post" action="demoform.asp"> <label for="fname" class="ui-hidden-accessible">姓名:</label> <input type="text" name="fname" id="fname" placeholder="姓名..."> </form>
2、域容器:
如果需要 label 和表单元素在宽屏幕上显示正常,用带有 data-role="fieldcontain" 属性的 <div> 或<fieldset>包装 label 或表单元素:
<form method="post" action="demoform.asp"> <div data-role="fieldcontain"> <label for="fname">First name:</label> <input type="text" name="fname" id="fname"> <label for="lname">Last name:</label> <input type="text" name="lname" id="lname"> </div> </form>
fieldcontain 属性基于页面宽度来设置 label 和表单控件的样式。当页面宽度大于 480px 时,它会自动将 label 与表单控件放置于同一行。当小于 480px 时,label 会被放置于表单元素之上。
3、单选按钮:
<form method="post" action="demoform.asp"> <div data-role="controlgroup"> <legend>Choose your gender:</legend> <label for="male">Male</label> <input type="radio" name="gender" id="male" value="male"> <label for="female">Female</label> <input type="radio" name="gender" id="female" value="female"> </div> </form> <!-- 需要添加label和id -->
4、表单选择:
<!-- 分组 --> <select name="day" id="day"> <optgroup label="Weekdays"> <option value="mon">Monday</option> <option value="tue">Tuesday</option> <option value="wed">Wednesday</option> </optgroup> <optgroup label="Weekends"> <option value="sat">Saturday</option> <option value="sun">Sunday</option> </optgroup> </select>
<!-- 多选 --> <select name="day" id="day" multiple data-native-menu="false">
5、滑块:
<form method="post" action="demoform.asp"> <div data-role="fieldcontain"> <label for="points">Points:</label> <input type="range" data-highlight="true" name="points" id="points" value="50" min="0" max="100"> </div> </form>
6、切换开关:
<form method="post" action="demoform.asp"> <div data-role="fieldcontain"> <label for="switch">Toggle Switch:</label> <select name="switch" id="switch" data-role="slider"> <option value="on" selected>On</option> <option value="off">Off</option> </select> </div> </form>
tips:清除JQM自动样式:data-role:none
jQuery Mobile 会自动通过 AJAX 进行表单提交
