织梦实现ajax用户注册功能

介绍织梦实现ajax用户注册功能前，我们先看一下注册表单的样式，如下图。

//表单提交时先走Doreg() js函数。

<form onsubmit="return Doreg();">
    <input type="hidden" name="fmdo" value="reg">
    <h3>注册<p class="status"></p></h3>
    <p class="user_name">
        <input id="user_name" type="text" name="user_name" placeholder="输入英文登录名">
    </p>
    <p class="user_pass">
        <input id="user_pass" type="password" name="user_pass" placeholder="密码最小长度为6">
    </p>
    <p class="user_pass2">
        <input type="password" id="user_pass2" name="user_pass2" placeholder="再次输入密码">
    </p>
    <p class="user_email">
        <input id="user_email" type="email" name="user_email" placeholder="输入常用邮箱">
    </p>
    <p class="vdcode_reg">
        <input type="text" id="vdcode_reg" name="vdcode_reg" placeholder="验证码">
        <img id="vdcode_reg" onclick="this.src=this.src+'?'" alt="看不清？点击更换" src="/include/vdimgck.php">
    </p>
    <p>
        <input type="submit" value="注册" name="submit">
    </p>
</form>
