(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

{syntaxhighlighter brush: php} 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}.") }, {/syntaxhighlighter}

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.

{syntaxhighlighter brush: php}

{/syntaxhighlighter}

 

然后引入下面这四个js文件:

{syntaxhighlighter brush: php} {/syntaxhighlighter}

然后自定义一个js文件,这个js文件的内容如下:

{syntaxhighlighter brush: php} $("#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: " 请输入用户名", minlength: jQuery.format(" 用户名不正确,应该在2个汉字或四个字符以上") }, email: { required: "请输入Email地址", email: " 请输入正确的email地址" }, password: { required: " 请输入密码", minlength: jQuery.format(" 您输入的密码不正确,应该在6位或6位字符以上") }, confirm_password: { required: "请输入确认密码", minlength: jQuery.format(" 您输入的密码不正确,应该在6位或6位字符以上"), equalTo: "两次输入密码不一致" } } }); {/syntaxhighlighter}

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
