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>
4、登錄案例：
<div class="row">
<div class="col-sm-12">
<form id="loginForm" class="formValidate" novalidate="novalidate">
<h2 class="no-margins" style="color:#999;font-weight: bold">登錄：</h2>
<p class="m-t-md" style="color:#999;font-weight: bold">進銷存售后管理系統</p>
<div class="form-group">
<input type="text" class="form-control uname" placeholder="用戶名" name="username" id="username" required />
</div>
<div class="form-group">
<input type="password" class="form-control pword" placeholder="密碼" name="password" id="password" required />
</div>
<a href="">忘記密碼了？</a>
<button class="btn btn-success btn-block" type="submit" onclick="return login()">登錄</button>
</form>
</div>
</div>
function login(){
let flag = $('#loginForm').valid();
if(!flag) return;
let username = $("#username").val();
let pwd = $("#password").val();
let loginUrl = baseUrl + "/login?loginName="+username+"&pwd="+pwd;
$.post(loginUrl,function (data) {
if(data == "name_or_pwd_wrong"){
alert("用戶或者密碼錯誤");
return false;
}else if(data == "fail"){
alert("登錄失敗");
return false;
}else{
let jsonData = eval('('+data+')');
window.location.href = "index.html";
$.cookie(jxc_username, jsonData.userName);
$.cookie(jxc_useruiqueid, jsonData.userId);
$.cookie(jxc_userroleid, jsonData.roleId);
return true;
}
});
}
$().ready(function () {
$("#loginForm").validate({
submitHandler: function (form) {
}
});
});
