下面将为您详细讲解关于“Bootstrap Validator模态框、JSP、表单验证和Ajax提交功能”的攻略。
什么是Bootstrap Validator?
Bootstrap Validator是一种 jQuery 插件,可用于验证表单。它具有与Bootstrap框架相同的外观和感觉,并且可以轻松地用于您的Bootstrap项目。
Bootstrap Validator模态框表单验证
在使用Bootstrap Validator时,您可以对表单进行验证以确保它们包含正确的数据。以下是使用Bootstrap Validator在模态框表单中进行验证的步骤:
- 在Head标签中引入必要的样式和脚本:
<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/jquery.bootstrapvalidator/0.5.3/css/bootstrapValidator.min.css">
<script src="https://cdn.jsdelivr.net/jquery.bootstrapvalidator/0.5.3/js/bootstrapValidator.min.js"></script>
- 使用以下代码创建一个表单:
<form id="form_id" method="post">
<div class="form-group">
<label for="name">Name:</label>
<input type="text" class="form-control" name="name" id="name">
</div>
<div class="form-group">
<label for="email">Email address:</label>
<input type="email" class="form-control" name="email" id="email">
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
- 在Javascript中,使用以下代码初始化验证:
<script>
$(document).ready(function() {
$('#form_id').bootstrapValidator({
fields: {
name: {
validators: {
notEmpty: {
message: 'The Name field is required'
}
}
},
email: {
validators: {
notEmpty: {
message: 'The Email field is required'
},
emailAddress: {
message: 'Please enter a valid email address'
}
}
}
}
})
});
</script>
此时表单的空值和邮箱格式都将被验证,并在未通过验证时显示错误信息。
Bootstrap Validator模态框、表单验证和Ajax提交
使用Bootstrap Validator,可以使用Ajax提交模态框中的表单,并在成功时关闭模态框。以下是示例代码:
HTML文件:
<button class="btn btn-primary" data-toggle="modal" data-target="#myModal">Add a new user</button>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">New User</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form id="newUserForm">
<div class="form-group">
<label for="first_name">First Name:</label>
<input type="text" class="form-control" id="first_name" name="first_name">
</div>
<div class="form-group">
<label for="last_name">Last Name:</label>
<input type="text" class="form-control" id="last_name" name="last_name">
</div>
<div class="form-group">
<label for="email">Email:</label>
<input type="email" class="form-control" id="email" name="email">
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary submitBtn">Create User</button>
</div>
</div>
</div>
</div>
JS文件:
<script>
$(document).ready(function () {
$('#newUserForm').bootstrapValidator({
fields: {
first_name: {
validators: {
notEmpty: {
message: 'The First Name field is required'
}
}
},
last_name: {
validators: {
notEmpty: {
message: 'The Last Name field is required'
}
}
},
email: {
validators: {
notEmpty: {
message: 'The Email field is required'
},
emailAddress: {
message: 'Please enter a valid email address'
}
}
}
},
submitHandler: function(validator, form, submitButton) {
$.ajax({
url: 'addUser.jsp',
type: 'post',
data: $('#newUserForm').serialize(),
success: function(data) {
if (data == 'success') {
$('#myModal').modal('hide');
$('#newUserForm')[0].reset();
alert('User created successfully!');
} else {
alert('Error creating user!');
}
}
});
}
});
});
</script>
此示例中,当用户点击“Create User”按钮时,表单将通过Ajax发送到服务器。如果成功,模态框将关闭并重置表单。如果出现错误,则会显示适当的消息。
