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、默认效验规则
(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
默认提示
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")
});
三、使用方式
1、将校验规则写在控件中
使用class="{ }"的方式,必须引入包:jquery.metadata.js
<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>
2、将效验规则写到js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>
3、使用jQuery.validate.unobtrusive.js
原文地址:http://blog.darkthread.net/post-2011-07-27-unobtrusive-jquery-validation.aspx
ASP.NET MVC 3 加入了Unobtrusive jQuery Validation,通过在<input>加上data-val-* 等html5相容attribute注记,不需要额外的撰写javascript就能实现验证。
(1)<input>元素加上data-val="true",注明要启用客户端验证
(2)有些验证规则需要额外参数,可通过data-val-rulename-parameterName方式指定,如:data-val-length-max="60"
(3)在<input>后方加上<span data-balmsg-for="inputName" data-valmsg-replace="true/false"></span>标注显示错误信息的位置,如果错误信息要汇总显示,放入一个<div data-valmsg-summary="true"></div>
<script src=".../jQuery/jquery-1.6.2.js" type="text/javascript"></script>
<script src=".../jquery.validate.js" type="text/javascript"></script>
<script src=".../jquery.validate.unobtrusive.js" type="text/javascript"></script>
<form id="form1" method="get">
<div data-valmsg-summary="true"><ul></ul></div>
<div>
<input type="text" id="tReq" name="tReq" data-val="true" data-val-required="不可空白"/>
<span data-valmsg-for="tReq"></span>
</div>
<div>
<input type="text" id="tAccept" name="tAccept" value="a.doc" data-val="true" data-val-accept="檔名須為.jpg、.gif或.png" data-val-accept-exts="jpg|gif|png" />
<span data-valmsg-for="tAccept"></span>
</div>
<div>
<input type="text" id="tRegex" name="tRegex" value="123-ABC@" data-val="true" data-val regex="車牌格式須為999-999" data-val-regex-pattern="[0-9A-Z]{3}-[0-9A-Z]{3}" />
<span data-valmsg-for="tRegex"></span>
</div>
<div>
<input type="text" id="tDigit" name="tDigit" value="-1234" data-val="true" data-val digits="只接受數字字元"/>
<span data-valmsg-for="tDigit"></span>
</div>
<div>
<input type="text" id="tNum" name="tNum" value="-1,234.56A" data-val="true" data-val number="必須為有效數字"/>
<span data-valmsg-for="tNum"></span>
</div>
<div>
<input type="text" id="tDate" name="tDate" value="X/01/X2000" data-val="true" data-val date="必須為日期(僅粗略檢查)"/>
<span data-valmsg-for="tDate"></span>
</div>
<div>
<input type="text" id="tEmail" name="tEmail" value="jeffrey @mail.com" data-val="true" data-val-email="必須為Email"/>
<span data-valmsg-for="tEmail"></span>
</div>
<div>
<input type="text" id="tUrl" name="tUrl" value="http:// blog.darkthread.net" data-val="true" data-val-url="必須為有效網址"/>
<span data-valmsg-for="tUrl"></span>
</div>
<div>
<input type="text" id="tLen" name="tLen" value="TTT" data-val="true" data-val-length="長度須介於4到8之間" data-val-length-min="4" data-val-length-max="8" />
<span data-valmsg-for="tLen"></span>
</div>
<div>
<input type="text" id="tRange" name="tRange" value="5" data-val="true" data-val-range="須介於10到100" data-val-range-min="10" data-val-range-max="100" />
<span data-valmsg-for="tRange"></span>
</div>
<div>
<input type="text" id="tEq" name="tEq" value="99" data-val="true" data-val-equalto="必須與上方欄位內容相同" data-val-equalto-other="tRange" />
<span data-valmsg-for="tEq"></span>
</div>
<div>
<input type="submit" id="send" value="Send" />
</form>
</body>
</html>
四、其他
jquery.validate的一些扩展验证方法
当validate无法满足我们的验证要求的时候,我们可以自定义一些需要的验证方法
