首先，利用bootstrap Validator表单验证进行表单验证需要如下CSS和JS.
<link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
<link rel="stylesheet" type="text/css" href="css/bootstrapValidator.css" />
<script src="js/jquery-1.10.2.min.js" type="text/javascript"></script>
<script src="js/bootstrap.js" type="text/javascript"></script>
<script src="js/bootstrapValidator.js"></script>
这些样式和Js可以百度下载，或者到bootstrap-validator的github上找https://github.com/1000hz/bootstrap-validator
其次，我们需要严格遵守相应的格式
代码示例如下：
<!DOCTYPE html>
<html>
<head>
<title>BootstrapValidator demo</title>
<link rel="stylesheet" href="../vendor/bootstrap/css/bootstrap.css"/>
<link rel="stylesheet" href="../dist/css/bootstrapValidator.css"/>
<script type="text/javascript" src="../vendor/jquery/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="../vendor/bootstrap/js/bootstrap.min.js"></script>
<script type="text/javascript" src="../dist/js/bootstrapValidator.js"></script>
</head>
<body>
<div class="container">
<div class="row">
<div class="page-header">
<h1>Use error message that is returned from remote/callback validator</h1>
</div>
<div class="col-lg-8 col-lg-offset-2">
<form id="defaultForm" method="post" class="form-horizontal" action="target.php">
<div class="form-group">
<label class="col-lg-3 control-label">Username</label>
<div class="col-lg-5">
<input type="text" class="form-control" name="username" autocomplete="off" />
</div>
</div>
<div class="form-group">
<label class="col-lg-3 control-label">Email address</label>
<div class="col-lg-5">
<input type="text" class="form-control" name="email" autocomplete="off" />
</div>
</div>
<div class="form-group">
<label class="col-lg-3 control-label">Password</label>
<div class="col-lg-5">
<input type="password" class="form-control" name="password" />
</div>
</div>
<div class="form-group">
<div class="col-lg-9 col-lg-offset-3">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
</div>
</div>
<script type="text/javascript">
$(document).ready(function() {
$('#defaultForm').bootstrapValidator({
message: 'This value is not valid',feedbackIcons: {
valid: 'glyphicon glyphicon-ok',invalid: 'glyphicon glyphicon-remove',validating: 'glyphicon glyphicon-refresh'
},fields: {
username: {
message: 'The username is not valid',validators: {
notEmpty: {
message: 'The username is required and can\'t be empty'
},remote: {
url: 'remote2.php'
},different: {
field: 'password',message: 'The username and password can\'t be the same as each other'
}
}
},email: {
validators: {
notEmpty: {
message: 'The email address is required and can\'t be empty'
},emailAddress: {
message: 'The input is not a valid email address'
},remote: {
url: 'remote2.php'
}
}
},password: {
validators: {
notEmpty: {
message: 'The password is required and can\'t be empty'
},different: {
field: 'username',message: 'The password can\'t be the same as username'
},callback: {
callback: function(value,validator) {
// Check the password strength
if (value.length < 6) {
return {
valid: false,message: 'The password must be more than 6 characters'
}
}
if (value === value.toLowerCase()) {
return {
valid: false,message: 'The password must contain at least one upper case character'
}
}
if (value === value.toUpperCase()) {
return {
valid: false,message: 'The password must contain at least one lower case character'
}
}
if (value.search(/[0-9]/) < 0) {
return {
valid: false,message: 'The password must contain at least one digit'
}
}
return true;
}
}
}
}
}
});
});
</script>
</body>
</html>当然这些代码在demo中都有。而我们需要修改为下面的ajax异步表单验证的形式，所以我们需要对原来代码进行修改。
<!DOCTYPE html>
<html>
<head>
<title>BootstrapValidator demo</title>
<link rel="stylesheet" href="../vendor/bootstrap/css/bootstrap.css"/>
<link rel="stylesheet" href="../dist/css/bootstrapValidator.css"/>
<script type="text/javascript" src="../vendor/jquery/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="../vendor/bootstrap/js/bootstrap.min.js"></script>
<script type="text/javascript" src="../dist/js/bootstrapValidator.js"></script>
</head>
<body>
<div class="container">
<div class="row">
<div class="page-header">
<h1>Use error message that is returned from remote/callback validator</h1>
</div>
<div class="col-lg-8 col-lg-offset-2">
<form id="defaultForm" method="post" class="form-horizontal" action="target.php">
<div class="form-group">
<label class="col-lg-3 control-label">Username</label>
<div class="col-lg-5">
<input type="text" class="form-control" name="username" autocomplete="off" />
</div>
</div>
<div class="form-group">
<label class="col-lg-3 control-label">Email address</label>
<div class="col-lg-5">
<input type="text" class="form-control" name="email" autocomplete="off" />
</div>
</div>
<div class="form-group">
<label class="col-lg-3 control-label">Password</label>
<div class="col-lg-5">
<input type="password" class="form-control" name="password" />
</div>
</div>
<div class="form-group">
<div class="col-lg-9 col-lg-offset-3">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
</div>
</div>
<script type="text/javascript">
$(document).ready(function() {
$('#defaultForm').bootstrapValidator({
message: 'This value is not valid',remote : {
url : 'api/check_username',message : "该用户名已经存在！",delay : 500,type : 'post',},message: 'The password must contain at least one digit'
}
}
return true;
}
}
}
}
}
});
});
</script>
</body>
</html>可以看到我们在第一个字段 username中的remote添加了ajax验证。delay表示的是ajax刷新的时间是0.5秒一次。
在后台中，我们只需要返回一个true或一个false。
