下面是html代码
  <tr>    <td class="textR"><span class="f14">手机号码</span>:</td>    <td><input type="text"  name="mobile" class="txtInput" id="mobile"></td>    <td class="color999"><span class="red">*</span><span id="_mobile"></span></td>  </tr>

这段代码不完整,前面应该还有获取和转换的代码

如果用的是ajax,那就是请求界面的返回值

这可能是程序规范的返回值 约定俗成 所以要往上看这个$ucresult 是如何赋值的

这可能是程序规范的返回值 约定俗成 所以要往上看这个$ucresult 是如何赋值的 妞妞  你说我不懂这些类什么的东东。是不是说我是个水货程序员?懂是懂点,但是就是不会写

约定俗成的数值啦
你得看看常量UC_API_FUNC的值的同名函数
把'user', 'check_email', array('email'=>$email) 三个传进去会有什么结果
可能还要向上追溯

uc 的api 和函数 查他们的手册吧 应该有提到的
