jQuery Validate 驗證 文件驗證

jQuery Validate

jQuery Validate 插件為表單提供了強大的驗證功能，讓客戶端表單驗證變得更簡單，同時提供了大量的定制選項，滿足應用程序各種需求。

1、導入 js 庫

<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>

2、默認校驗規(guī)則

例子：

$().ready(function() {// 在鍵盤按下并釋放及提交后驗證提交表單
  $("#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: "請輸入您的名字",
      lastname: "請輸入您的姓氏",
      username: {
        required: "請輸入用戶名",
        minlength: "用戶名必需由兩個字母組成"
      },
      password: {
        required: "請輸入密碼",
        minlength: "密碼長度不能小于 5 個字母"
      },
      confirm_password: {
        required: "請輸入密碼",
        minlength: "密碼長度不能小于 5 個字母",
        equalTo: "兩次密碼輸入不一致"
      },
      email: "請輸入一個正確的郵箱",
      agree: "請接受我們的聲明",
      topic: "請選擇兩個主題"
     }
    })});
