jquery.validate.unobtrusive.js的用法:

jquery.validate.unobtrusive.js使用上很简洁,只要对Tag下几个属性即可以使用!

引用JavaScript<script src="http://code.jquery.com/jquery-1.6.2.min.js"></script> <script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.8.1/jquery.validate.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.validate.unobtrusive.min.js"></script>
最新的CDN JS引用可以查看,http://www.asp.net/ajaxLibrary/CDN.ashx
<label for="tId">Domain Account:<label data-valmsg-for="tId"></label></label>
<input type="text" id="tId" runat="server" data-val="true" data-val-required="请输入帐号"/><label for="tPwd">Password:<label data-valmsg-for="tPwd"></label></label>
<input type="text" id="tPwd" runat="server" runat="server" data-val="true" data-val-required="请输入密码"/>
<asp:Button ID="btnSignIn" runat="server" Text="Sign In" onclick="btnSignIn_Click" /> 测试jquery.validate.unobtrusive.js的用法
 
jQuery验证控件jquery.validate.js:

jQuery校验

官网地址: http://bassistance.de/jquery-plugins/jquery-plugin-validation

一导入js库

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

二、默认校验规则

(1)required:true  必输字段
(2)remote:"check.php"  使用ajax方法调用check.php验证输入值
(3)email:true  必须输入正确格式的电子邮件
(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 日期校验ie6出错,慎用
(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
(10)equalTo:"#field"  输入值必须和#field相同
(11)accept:  输入拥有合法后缀名的字符串(上传文件的后缀)
(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

三、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,可在js代码中加入:

jQuery.extend(jQuery.validator.messages, {
required: "必选字段",
remote: "请修正该字段",
email: "请输入正确格式的电子邮件",
url: "请输入合法的网址",
date: "请输入合法的日期",
dateISO: "请输入合法的日期 (ISO).",
number: "请输入合法的数字",
digits: "只能输入整数",
creditcard: "请输入合法的信用卡号",
equalTo: "请再次输入相同的值",
accept: "请输入拥有合法后缀名的字符串",
maxlength: jQuery.validator.format("请输入一个 长度最多是 {0} 的字符串"),
minlength: jQuery.validator.format("请输入一个 长度最少是 {0} 的字符串"),
rangelength: jQuery.validator.format("请输入 一个长度介于 {0} 和 {1} 之间的字符串"),
range: jQuery.validator.format("请输入一个介于 {0} 和 {1} 之间的值"),
max: jQuery.validator.format("请输入一个最大为{0} 的值"),
min: jQuery.validator.format("请输入一个最小为{0} 的值")
});

推荐做法,将此文件放入messages_cn.js中,在页面中引入
<script src="../js/messages_cn.js" type="text/javascript"></script>

四、使用方式

1.将校验规则写到控件中

<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>

$().ready(function() {
$("#signupForm").validate();
});

<form id="signupForm" method="get" action="">
<p>
<label for="firstname">Firstname</label>
<input id="firstname" name="firstname" class="required" />
</p>
<p>
<label for="email">E-Mail</label>
<input id="email" name="email" class="required email" />
</p>
<p>
<label for="password">Password</label>
<input id="password" name="password" type="password" class="{required:true,minlength:5}" />
</p>
<p>
<label for="confirm_password">确认密码</label>
<input id="confirm_password" name="confirm_password" type="password" class="{required:true,minlength:5,equalTo:'#password'}" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</form>

使用class="{}"的方式,必须引入包:jquery.metadata.js

可以使用如下的方法,修改提示内容:
class="{required:true,minlength:5,messages:{required:'请输入内容'}}"

在使用equalTo关键字时,后面的内容必须加上引号,如下代码:
class="{required:true,minlength:5,equalTo:'#password'}"

2.将校验规则写到js代码中

$().ready(function() {
$("#signupForm").validate({
rules: {
firstname: "required",
email: {
required: true,
email: true
},
password: {
required: true,
minlength: 5
},
confirm_password: {
required: true,
minlength: 5,
equalTo: "#password"
}
},
messages: {
firstname: "请输入姓名",
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("密码不能小于{0}个字 符")
},
confirm_password: {
required: "请输入确认密码",
minlength: "确认密码不能小于5个字符",
equalTo: "两次输入密码不一致不一致"
}
}
});
});

//messages处,如果某个控件没有message,将调用默认的信息

<form id="signupForm" method="get" action="">
<p>
<label for="firstname">Firstname</label>
<input id="firstname" name="firstname" />
</p>
<p>
<label for="email">E-Mail</label>
<input id="email" name="email" />
</p>
<p>
<label for="password">Password</label>
<input id="password" name="password" type="password" />
</p>
<p>
<label for="confirm_password">确认密码</label>
<input id="confirm_password" name="confirm_password" type="password" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</form>

required:true 必须有值
required:"#aa:checked"表达式的值为真,则需要验证
required:function(){}返回为真,表时需要验证
后边两种常用于,表单中需要同时填或不填的元素
