怎么用jquery.validate.js 进行 remote 后台验证

Answer 1

两种方式。

1、将校验规则写到控件中

<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script>
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script>
<script src="http://static.runoob.com/assets/jquery-validation-1.14.0/dist/localization/messages_zh.js"></script>
<script>
$.validator.setDefaults({
    submitHandler: function() {
      alert("提交事件!");
    }
});
$().ready(function() {
    $("#commentForm").validate();
});
</script>
<form class="cmxform" id="commentForm" method="get" action="">
  <fieldset>
    <legend>输入您的名字，邮箱，URL，备注。</legend>
    <p>
      <label for="cname">Name (必需, 最小两个字母)</label>
      <input id="cname" name="name" minlength="2" type="text" required>
    </p>
    <p>
      <label for="cemail">E-Mail (必需)</label>
      <input id="cemail" type="email" name="email" required>
    </p>
    <p>
      <label for="curl">URL (可选)</label>
      <input id="curl" type="url" name="url">
    </p>
    <p>
      <label for="ccomment">备注 (必需)</label>
      <textarea id="ccomment" name="comment" required></textarea>
    </p>
    <p>
      <input class="submit" type="submit" value="Submit">
    </p>
  </fieldset>
</form>

2、将校验规则写到 js 代码中

$().ready(function() {
// 在键盘按下并释放及提交后验证提交表单
  $("#signupForm").validate({
    rules: {
      firstname: "required",
      lastname: "required",
      username: {
        required: true,
        minlength: 2
      },
      password: {
        required: true,
        minlength: 5
      },
      confirm_password: {
        required: true,
        minlength: 5,
        equalTo: "#password"
      },
      email: {
        required: true,
        email: true
      },
      topic: {
        required: "#newsletter:checked",
        minlength: 2
      },
      agree: "required"
    },
    messages: {
      firstname: "请输入您的名字",
      lastname: "请输入您的姓氏",
      username: {
        required: "请输入用户名",
        minlength: "用户名必需由两个字母组成"
      },
      password: {
        required: "请输入密码",
        minlength: "密码长度不能小于 5 个字母"
      },
      confirm_password: {
        required: "请输入密码",
        minlength: "密码长度不能小于 5 个字母",
        equalTo: "两次密码输入不一致"
      },
      email: "请输入一个正确的邮箱",
      agree: "请接受我们的声明",
      topic: "请选择两个主题"
    }
});
messages 处，如果某个控件没有 message，将调用默认的信息
<form class="cmxform" id="signupForm" method="get" action="">
  <fieldset>
    <legend>验证完整的表单</legend>
    <p>
      <label for="firstname">名字</label>
      <input id="firstname" name="firstname" type="text">
    </p>
    <p>
      <label for="lastname">姓氏</label>
      <input id="lastname" name="lastname" type="text">
    </p>
    <p>
      <label for="username">用户名</label>
      <input id="username" name="username" type="text">
    </p>
    <p>
      <label for="password">密码</label>
      <input id="password" name="password" type="password">
    </p>
    <p>
      <label for="confirm_password">验证密码</label>
      <input id="confirm_password" name="confirm_password" type="password">
    </p>
    <p>
      <label for="email">Email</label>
      <input id="email" name="email" type="email">
    </p>
    <p>
      <label for="agree">请同意我们的声明</label>
      <input type="checkbox" class="checkbox" id="agree" name="agree">
    </p>
    <p>
      <label for="newsletter">我乐意接收新信息</label>
      <input type="checkbox" class="checkbox" id="newsletter" name="newsletter">
    </p>
    <fieldset id="newsletter_topics">
      <legend>主题 (至少选择两个) - 注意：如果没有勾选“我乐意接收新信息”以下选项会隐藏，但我们这里作为演示让它可见</legend>
      <label for="topic_marketflash">
        <input type="checkbox" id="topic_marketflash" value="marketflash" name="topic">Marketflash
      </label>
      <label for="topic_fuzz">
        <input type="checkbox" id="topic_fuzz" value="fuzz" name="topic">Latest fuzz
      </label>
      <label for="topic_digester">
        <input type="checkbox" id="topic_digester" value="digester" name="topic">Mailing list digester
      </label>
      <label for="topic" class="error">Please select at least two topics you'd like to receive.</label>
    </fieldset>
    <p>
      <input class="submit" type="submit" value="提交">
    </p>
  </fieldset>
</form>
