Jquery validate插件是一个客户端验证极品。在jquery.validate.js中有默认校验规则和默认的提示

(一)默认校验规则

(4) url:true                      必须输入正确格式的网址
(5) date:true                   必须输入正确格式的日期
(6) dateISO:true              必须输入正确格式的日期(ISO)，例如：2009-06-23，1998/01/22 只验证格式，不验证有效性
(7) number:true              必须输入合法的数字(负数，小数)
(8) digits:true                 必须输入整数
(9) creditcard:                 必须输入合法的信用卡号

(12) maxlength:5            输入长度最多是5的字符串(汉字算一个字符)
(13) minlength:10           输入长度最小是10的字符串(汉字算一个字符)
(14) rangelength:[5,10]   输入长度必须介于 5 和 10 之间的字符串")(汉字算一个字符)
(15) range:[5,10]             输入值必须介于 5 和 10 之间
(16) max:5                      输入值不能大于5
(17) min:10                     输入值不能小于10

(二)默认的提示

 
messages: {
    required: "This field is required.",
    remote: "Please fix this field.",
    email: "Please enter a valid email address.",
    url: "Please enter a valid URL.",
    date: "Please enter a valid date.",
    dateISO: "Please enter a valid date (ISO).",
    dateDE: "Bitte geben Sie ein g眉ltiges Datum ein.",
    number: "Please enter a valid number.",
    numberDE: "Bitte geben Sie eine Nummer ein.",
    digits: "Please enter only digits",
    creditcard: "Please enter a valid credit card number.",
    equalTo: "Please enter the same value again.",
    accept: "Please enter a value with a valid extension.",
    maxlength: $.validator.format("Please enter no more than {0} characters."),
    minlength: $.validator.format("Please enter at least {0} characters."),
    rangelength: $.validator.format("Please enter a value between {0} and {1} characters long."),
    range: $.validator.format("Please enter a value between {0} and {1}."),
    max: $.validator.format("Please enter a value less than or equal to {0}."),
    min: $.validator.format("Please enter a value greater than or equal to {0}.")
},

如需要修改这些提示信息，你可以在js代码中加入任何你想要输出显示的信息提示.

我们以最常用的注册表单验证来作为例子演示一下:

首先要有一个form表单,并定义form的id.

 
      <form action="" method="post" id="login">
        <label>用户名:</label><input name="username" type="text" />
        <label>邮件地址:</label><input name="email" type="text" />
        <label>密   码:</label><input  id="password" name="password" type="password"  />
        <label>确认密码:</label><input name="confirm_password" type="password" />
        <input name="userinfosub" type="submit" value="提交" />
    </form>

然后引入下面这四个js文件:

 
<script src="../js/jquery.js" type="text/javascript"></script>
<script src="../js/jquery.validate.js" type="text/javascript"></script>
<script src="./js/jquery.metadata.js" type="text/javascript"></script>
<script src="./js/messages_cn.js" type="text/javascript"></script>

然后自定义一个js文件,这个js文件的内容如下:

 
$("#login").validate({
    rules: {
       username: {
        required: true,
        minlength: 2
       },
       email: {
        required: true,
        email: true
       },
       password: {
        required: true,
        minlength: 6
       },
       confirm_password: {
        required: true,
        minlength: 6,
        equalTo: "#password"
       }
      },
    messages: {
       username: {
        required: "<span style='color:red'>  请输入用户名</span>",
        minlength: jQuery.format("<span style='color:red'>  用户名不正确，应该在2个汉字或四个字符以上</span>")
       },
       email: {
        required: "<span style='color:red''>请输入Email地址</span>",
        email: "<span style='color:red'>  请输入正确的email地址</span>"
       },
       password: {
        required: "<span style='color:red'>  请输入密码</span>",
        minlength: jQuery.format("<span style='color:red'>  您输入的密码不正确，应该在6位或6位字符以上</span>")
       },
       confirm_password: {
        required: "<span style='color:red'>请输入确认密码</span>",
        minlength: jQuery.format("<span style='color:red'>  您输入的密码不正确，应该在6位或6位字符以上</span>"),
        equalTo: "<span class='fred'>两次输入密码不一致</span>"
       }
      }
    });

之后运行你的页面,测试即可.下面是直接提交时的验证效果.可以作为参考一下
