JQuery Validate使用總結

1、導入js庫 <script src="../js/jquery.js" type="text/javascript"></script>
<script src="../js/jquery.validate.js" type="text/javascript"></script>
 2、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: 輸入擁有合法後綴名的字符串（上傳文件的後綴）
(12)maxlength:5 輸入長度最可能是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] 輸入長度必須介於 5 和 10 之間的字符串")(漢字算一個字符)
(15)range:[5,10] 輸入值必須介於 5 和 10 之間
(16)max:5 輸入值不能大於5
(17)min:10 輸入值不能小於10

3、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}.")
},
如須要修改，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: "請輸入擁有合法後綴名的字符串",
    maxlength: jQuery.validator.format("請輸入一個 長度最可能是 {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 一個長度介於 {0} 和 {1} 之間的字符串"),
    range: jQuery.validator.format("請輸入一個介於 {0} 和 {1} 之間的值"),
    max: jQuery.validator.format("請輸入一個最大爲{0} 的值"),
    min: jQuery.validator.format("請輸入一個最小爲{0} 的值")
});

推薦作法，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> 4、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
能夠使用以下的方法，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，後面的內容必須加上引號，以下代碼：
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("密碼不能小於{0}個字 符")
            },
            confirm_password: {
                required: "請輸入確認密碼",
                minlength: "確認密碼不能小於5個字符",
                equalTo: "兩次輸入密碼不一致不一致"
            }
        }
    });
});
//messages處，若是某個控件沒有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"表達式的值爲真，則須要驗證
required: function() {}返回爲真，表時須要驗證
後邊兩種經常使用於，表單中須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
        },

        }
    },
