JQuery Validate使用總結：
一、導入js庫
<script src="../js/jquery.js" type="text/javascript"></script>
<script src="../js/jquery.validate.js" type="text/javascript"></script>
如果也導入 jquery.validate.unobtrusive可能會沖突驗證沒有作用
二、默認校驗規則
(1)required:true 必輸字段
(2)remote:"check.php" 使用ajax方法調用check.php驗證輸入值
(3)email:true 必須輸入正確格式的電子郵件
(4)url:true 必須輸入正確格式的網址
(5)date:true 必須輸入正確格式的日期 日期校驗ie6出錯，慎用
(6)dateISO:true 必須輸入正確格式的日期(ISO)，例如：2009-06-23，1998/01/22 只驗證格式，不驗證有效性
(7)number:true 必須輸入合法的數字(負數，小數)
(8)digits:true 必須輸入整數
(9)creditcard: 必須輸入合法的信用卡號
(10)equalTo:"#field" 輸入值必須和#field相同
(11)accept: 輸入擁有合法后綴名的字符串（上傳文件的后綴）
(12)maxlength:5 輸入長度最多是5的字符串(漢字算一個字符)
(13)minlength:10 輸入長度最小是10的字符串(漢字算一個字符)
(14)rangelength:[5,10] 輸入長度必須介于 5 和 10 之間的字符串")(漢字算一個字符)
(15)range:[5,10] 輸入值必須介于 5 和 10 之間
(16)max:5 輸入值不能大于5
(17)min:10 輸入值不能小于10
三、默認的提示
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代碼中加入：
jQuery.extend(jQuery.validator.messages, {
required: "必選字段",
remote: "請修正該字段",
email: "請輸入正確格式的電子郵件",
url: "請輸入合法的網址",
date: "請輸入合法的日期",
dateISO: "請輸入合法的日期 (ISO).",
number: "請輸入合法的數字",
digits: "只能輸入整數",
creditcard: "請輸入合法的信用卡號",
equalTo: "請再次輸入相同的值",
accept: "請輸入擁有合法后綴名的字符串",
maxlength: jQuery.validator.format("請輸入一個 長度最多是 {0} 的字符串"),
minlength: jQuery.validator.format("請輸入一個 長度最少是 {0} 的字符串"),
rangelength: jQuery.validator.format("請輸入 一個長度介于 {0} 和 {1} 之間的字符串"),
range: jQuery.validator.format("請輸入一個介于 {0} 和 {1} 之間的值"),
max: jQuery.validator.format("請輸入一個最大為{0} 的值"),
min: jQuery.validator.format("請輸入一個最小為{0} 的值")
});
推薦做法，將此文件放入messages_cn.js中，在頁面中引入
<script src="../js/messages_cn.js" type="text/javascript"></script>
四、使用方式1.將校驗規則寫到控件中
<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">確認密碼</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，必須引入包：jquery.metadata.js
可以使用如下的方法，修改提示內容：
class="{required:true,minlength:5,messages:{required:'請輸入內容'}}"
在使用equalTo關鍵字時，后面的內容必須加上引號，如下代碼：
class="{required:true,minlength:5,equalTo:'#password'}"
2.將校驗規則寫到js代碼中
$().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: "請輸入姓名",
email: {
required: "請輸入Email地址",
email: "請輸入正確的email地址"
},
password: {
required: "請輸入密碼",
minlength: jQuery.format("密碼不能小于{0}個字 符")
},
confirm_password: {
required: "請輸入確認密碼",
minlength: "確認密碼不能小于5個字符",
equalTo: "兩次輸入密碼不一致不一致"
}
}
});
});
//messages處，如果某個控件沒有message，將調用默認的信息
<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">確認密碼</label>
<input id="confirm_password" name="confirm_password" type="password" />
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</form>
required:true 必須有值
required:"#aa:checked"表達式的值為真，則需要驗證
required:function(){}返回為真，表時需要驗證
后邊兩種常用于，表單中需要同時填或不填的元素
demo：
$("#form1").validate({//JQ 前端校驗
rules: {
ctl00$MainContent$txtWebName: {
required: true,
maxlength: 500
},
ctl00$MainContent$txtShortName: {
maxlength: 500,
required: false
},
ctl00$MainContent$txtKeyWords: {
required: false,
maxlength: 500
},
ctl00$MainContent$txtGoodsNo: {
required: false,
maxlength: 250
},
ctl00$MainContent$txtRemark: {
required: false,
maxlength: 500
},
ctl00$MainContent$txtPageTitle: {
required: true,
maxlength: 1000
},
ctl00$MainContent$txtMetaKey: {
required: false,
maxlength: 1000
},
ctl00$MainContent$txtShowUrl: {
required: false,
maxlength: 2000,
url: true
},
ctl00$MainContent$txtOtherData: {
required: false,
maxlength: 1000
},
ctl00$MainContent$txtEC :{ required: true, digits: true},
ctl00$MainContent$txtFullEP : {required: true, digits: true},
ctl00$MainContent$txtMarketPrice : {required: true, number:true},
ctl00$MainContent$txtCash : {required: true,number:true},
ctl00$MainContent$txtDurationDays:{required: false,number:true},
ctl00$MainContent$txtFullCash:{required: true,number:true}
},
messages: {
ctl00$MainContent$txtWebName: "*請輸入商品名[限500字以內]",
ctl00$MainContent$txtShortName: "*限500字以內",
ctl00$MainContent$txtKeyWords: "*500字以內",
ctl00$MainContent$txtGoodsNo: "*250字以內",
ctl00$MainContent$txtRemark: "*500字以內",
ctl00$MainContent$txtPageTitle: "*請輸入分類頁面的標題",
ctl00$MainContent$txtMetaKey: "*1000字以內",
ctl00$MainContent$txtShowUrl: "*請輸入正確的URL地址",
ctl00$MainContent$txtOtherData: "*1000字以內",
ctl00$MainContent$txtEC:"*只能輸入整數",
ctl00$MainContent$txtFullEP:"*只能輸入整數",
ctl00$MainContent$txtCash:"*請輸入正確的現金數",
ctl00$MainContent$txtFullCash:"*請輸入正確的現金數",
ctl00$MainContent$txtDurationDays:"必須輸入數字",
ctl00$MainContent$txtMarketPrice:"*請輸入正確的市場價格"
}
}); //validate
自定義驗證規則
jQuery.validator.addMethod("gt", function (value, element, param) {
var r = ($("#abc").val()=="abc");
return r;
}, $.validator.format("輸入值必須大于{0}!"));
