JQuery Validate使用總結(jié)：
一、導(dǎo)入js庫(kù)
<script src="../js/jquery.js" type="text/javascript"></script>
<script src="../js/jquery.validate.js" type="text/javascript"></script>
如果也導(dǎo)入 jquery.validate.unobtrusive可能會(huì)沖突驗(yàn)證沒有作用
二、默認(rèn)校驗(yàn)規(guī)則
(1)required:true 必輸字段
(2)remote:"check.php" 使用ajax方法調(diào)用check.php驗(yàn)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(wǎng)址
(5)date:true 必須輸入正確格式的日期 日期校驗(yàn)ie6出錯(cuò)，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(yàn)證格式，不驗(yàn)證有效性
(7)number:true 必須輸入合法的數(shù)字(負(fù)數(shù)，小數(shù))
(8)digits:true 必須輸入整數(shù)
(9)creditcard: 必須輸入合法的信用卡號(hào)
(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(zhǎng)度最多是5的字符串(漢字算一個(gè)字符)
(13)minlength:10 輸入長(zhǎng)度最小是10的字符串(漢字算一個(gè)字符)
(14)rangelength:[5,10] 輸入長(zhǎng)度必須介于 5 和 10 之間的字符串")(漢字算一個(gè)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(rèn)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(qǐng)修正該字段",
email: "請(qǐng)輸入正確格式的電子郵件",
url: "請(qǐng)輸入合法的網(wǎng)址",
date: "請(qǐng)輸入合法的日期",
dateISO: "請(qǐng)輸入合法的日期 (ISO).",
number: "請(qǐng)輸入合法的數(shù)字",
digits: "只能輸入整數(shù)",
creditcard: "請(qǐng)輸入合法的信用卡號(hào)",
equalTo: "請(qǐng)?jiān)俅屋斎胂嗤闹?,
accept: "請(qǐng)輸入擁有合法后綴名的字符串",
maxlength: jQuery.validator.format("請(qǐng)輸入一個(gè) 長(zhǎng)度最多是 {0} 的字符串"),
minlength: jQuery.validator.format("請(qǐng)輸入一個(gè) 長(zhǎng)度最少是 {0} 的字符串"),
rangelength: jQuery.validator.format("請(qǐng)輸入 一個(gè)長(zhǎng)度介于 {0} 和 {1} 之間的字符串"),
range: jQuery.validator.format("請(qǐng)輸入一個(gè)介于 {0} 和 {1} 之間的值"),
max: jQuery.validator.format("請(qǐng)輸入一個(gè)最大為{0} 的值"),
min: jQuery.validator.format("請(qǐng)輸入一個(gè)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(yàn)規(guī)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(rèn)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(nèi)容：
class="{required:true,minlength:5,messages:{required:'請(qǐng)輸入內(nèi)容'}}"
在使用equalTo關(guān)鍵字時(shí)，后面的內(nèi)容必須加上引號(hào)，如下代碼：
class="{required:true,minlength:5,equalTo:'#password'}"
2.將校驗(yàn)規(guī)則寫到j(luò)s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(qǐng)輸入姓名",
email: {
required: "請(qǐng)輸入Email地址",
email: "請(qǐng)輸入正確的email地址"
},
password: {
required: "請(qǐng)輸入密碼",
minlength: jQuery.format("密碼不能小于{0}個(gè)字 符")
},
confirm_password: {
required: "請(qǐng)輸入確認(rèn)密碼",
minlength: "確認(rèn)密碼不能小于5個(gè)字符",
equalTo: "兩次輸入密碼不一致不一致"
}
}
});
});
//messages處，如果某個(gè)控件沒有message，將調(diào)用默認(rèn)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(rèn)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(dá)式的值為真，則需要驗(yàn)證
required:function(){}返回為真，表時(shí)需要驗(yàn)證
后邊兩種常用于，表單中需要同時(shí)填或不填的元素
demo：
$("#form1").validate({//JQ 前端校驗(yàn)
rules: {
ctl00$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$txtWebName: "*請(qǐng)輸入商品名[限500字以內(nèi)]",
ctl00$MainContent$txtShortName: "*限500字以內(nèi)",
ctl00$MainContent$txtKeyWords: "*500字以內(nèi)",
ctl00$MainContent$txtGoodsNo: "*250字以內(nèi)",
ctl00$MainContent$txtRemark: "*500字以內(nèi)",
ctl00$MainContent$txtPageTitle: "*請(qǐng)輸入分類頁面的標(biāo)題",
ctl00$MainContent$txtMetaKey: "*1000字以內(nèi)",
ctl00$MainContent$txtShowUrl: "*請(qǐng)輸入正確的URL地址",
ctl00$MainContent$txtOtherData: "*1000字以內(nèi)",
ctl00$MainContent$txtEC:"*只能輸入整數(shù)",
ctl00$MainContent$txtFullEP:"*只能輸入整數(shù)",
ctl00$MainContent$txtCash:"*請(qǐng)輸入正確的現(xiàn)金數(shù)",
ctl00$MainContent$txtFullCash:"*請(qǐng)輸入正確的現(xiàn)金數(shù)",
ctl00$MainContent$txtDurationDays:"必須輸入數(shù)字",
ctl00$MainContent$txtMarketPrice:"*請(qǐng)輸入正確的市場(chǎng)價(jià)格"
}
}); //validate
自定義驗(yàn)證規(guī)則
jQuery.validator.addMethod("gt", function (value, element, param) {
var r = ($("#abc").val()=="abc");
return r;
}, $.validator.format("輸入值必須大于{0}!"));
