1、將校驗規則寫到控件中
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>菜鳥教程(runoob.com)</title> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/dist/localization/messages_zh.js"></script> <script> $.validator.setDefaults({ submitHandler: function() {
//驗證通過后執行這里
alert("提交事件!");
} }); $().ready(function() { $("#commentForm").validate(); }); </script> <style> .error{ color:red; } </style> </head> <body> <form class="cmxform" id="commentForm" method="get" action=""> <fieldset> <legend>輸入您的名字，郵箱，URL，備注。</legend> <p> <label for="cname">Name (必需, 最小兩個字母)</label> <input id="cname" name="name" minlength="2" type="text" required> </p> <p> <label for="cemail">E-Mail (必需)</label> <input id="cemail" type="email" name="email" required> </p> <p> <label for="curl">URL (可選)</label> <input id="curl" type="url" name="url"> </p> <p> <label for="ccomment">備注 (必需)</label> <textarea id="ccomment" name="comment" required></textarea> </p> <p> <input class="submit" type="submit" value="Submit"> </p> </fieldset> </form> </body> </html>
必填項未填寫：
必填項不符合輸入規則：
驗證通過：
2、將校驗規則寫到 js 代碼中
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>菜鳥教程(runoob.com)</title> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/dist/localization/messages_zh.js"></script> <script> $.validator.setDefaults({ submitHandler: function() { alert("提交事件!"); } }); $().ready(function() { // 在鍵盤按下並釋放及提交后驗證提交表單 $("#signupForm").validate({ rules: { firstname: "required", lastname: "required", username: { required: true, minlength: 2 }, password: { required: true, minlength: 5 }, confirm_password: { required: true, minlength: 5, equalTo: "#password" }, email: { required: true, email: true }, "topic[]": { required: "#newsletter:checked", minlength: 2 }, agree: "required" }, messages: { firstname: "請輸入您的名字", lastname: "請輸入您的姓氏", username: { required: "請輸入用戶名", minlength: "用戶名必需由兩個字母組成" }, password: { required: "請輸入密碼", minlength: "密碼長度不能小於 5 個字母" }, confirm_password: { required: "請輸入密碼", minlength: "密碼長度不能小於 5 個字母", equalTo: "兩次密碼輸入不一致" }, email: "請輸入一個正確的郵箱", agree: "請接受我們的聲明", topic: "請選擇兩個主題" } }); }); </script> <style> .error{ color:red; } </style> </head> <body> <form class="cmxform" id="signupForm" method="get" action=""> <fieldset> <legend>驗證完整的表單</legend> <p> <label for="firstname">名字</label> <input id="firstname" name="firstname" type="text"> </p> <p> <label for="lastname">姓氏</label> <input id="lastname" name="lastname" type="text"> </p> <p> <label for="username">用戶名</label> <input id="username" name="username" type="text"> </p> <p> <label for="password">密碼</label> <input id="password" name="password" type="password"> </p> <p> <label for="confirm_password">驗證密碼</label> <input id="confirm_password" name="confirm_password" type="password"> </p> <p> <label for="email">Email</label> <input id="email" name="email" type="email"> </p> <p> <label for="agree">請同意我們的聲明</label> <input type="checkbox" class="checkbox" id="agree" name="agree"> </p> <p> <label for="newsletter">我樂意接收新信息</label> <input type="checkbox" class="checkbox" id="newsletter" name="newsletter"> </p> <fieldset id="newsletter_topics"> <legend>主題 (至少選擇兩個) - 注意：如果沒有勾選“我樂意接收新信息”以下選項會隱藏，但我們這里作為演示讓它可見</legend> <label for="topic_marketflash"> <input type="checkbox" id="topic_marketflash" value="marketflash" name="topic[]">Marketflash </label> <label for="topic_fuzz"> <input type="checkbox" id="topic_fuzz" value="fuzz" name="topic[]">Latest fuzz </label> <label for="topic_digester"> <input type="checkbox" id="topic_digester" value="digester" name="topic[]">Mailing list digester </label> <label for="topic" class="error" style="display:none">至少選擇兩個</label> </fieldset> <p> <input class="submit" type="submit" value="提交"> </p> </fieldset> </form> </body> </html>
3、使用ajax方式提交數據時驗證表單
原始的未校驗字段的ajax方式提交：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form id="myform"> <fieldset> <legend>驗證表單</legend> <p> <label for="username">姓名</label> <input id="username" name="username" type="text"/> </p> <p> <input class="submit" type="submit" value="提交"/> </p> </fieldset> </form> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script> <script> $("#myform").click(function () { $.ajax({ url: "?act=valid", type: "POST", data: $(form).serialize(), dataType: "json", success: function (data) { //console.log(data); alert('提交成功'); $('#username').val(''); } }); }) </script> </body> </html> </html>
增加校驗的ajax提交方式如下：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form id="myform"> <fieldset> <legend>驗證表單</legend> <p> <label for="username">姓名</label> <input id="username" name="username" type="text"/> </p> <p> <input class="submit" type="submit" value="提交"/> </p> </fieldset> </form> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/lib/jquery.js"></script> <script src="https://static.runoob.com/assets/jquery-validation-1.14.0/dist/jquery.validate.min.js"></script> <script> // 在ajax提交前添加校驗 $("#myform").validate({ // 校驗規則 rules: { username: { required: true, rangelength: [2, 6] } }, // 校驗失敗時提示內容 messages: { username: { required: "請輸入姓名", rangelength: $.validator.format("姓名最小長度:{0}, 最大長度:{1}。") } }, submitHandler: function (form) { // 將核心的ajax提交代碼包含進此函數 $.ajax({ url: "?act=valid", type: "POST", data: $(form).serialize(), dataType: "json", success: function (data) { //console.log(data); alert('提交成功'); $('#username').val(''); } }); } }); </script> </body> </html>
