1)使用的js:

   jquery.validate.min.js

jquery.mobile-1.0a3.min.js

jquery.mobile-1.0a3.min.css

2)HTML表单

 

<div data-role="page" id="login">
    
    <div data-role="header">
        <h1>Acme Corporation</h1>
    </div>
    
    <div data-role="content">
        
        <form id="frmLogin" class="validate">
            <div data-role="fieldcontain">
                <label for="email">[i]* [/i] Email: </label>
                <input type="text" id="email" name="email" 
                    class="required email" />
            </div>
            
            <div data-role="fieldcontain">
                <label for="password">[i]* [/i]Password: </label>
                <input type="password" id="password" name="password"
                    class="required" />
            </div>
            
            <div class="ui-body ui-body-b">
                <button class="btnLogin" type="submit" 
                    data-theme="a">Login</button>
            </div>
        </form>
        
    </div>
    
</div>

  可以看到,加上class="required"即完成必须输入项的验证

3 验证的JS其实很简单,跟普通的jquery validate一样

   $("#frmLogin").validate({

    submitHandler: function(form) {

        console.log("Call Login Action");

    }

});

   如果验证成功,则执行真正逻辑部分

4 jquery mobile还提供了横向和竖向手机切换屏时的CSS样式切换,如下:

 

.portrait label.error, .landscape label.error {
    color: red;
    font-size: 16px;
    font-weight: normal;
    line-height: 1.4;
    margin-top: 0.5em;
    width: 100%;
    float: none;
}

.landscape label.error { display: inline-block; margin-left: 22%; }

.portrait label.error { margin-left: 0; display: block; }

em { color: red; font-weight: bold; padding-right: .25em; }
