我有一个简单的登录表单,如下所示,附带一个 jQuery 脚本。我正在尝试使用 jQuery 进行一些简单的客户端表单验证。但是,我似乎无法触发模糊事件。我想不出我做错了什么,我尝试使用 '.on('blur', fn(){})' 但这也不起作用。请帮忙!
这是我的 HTML 文件:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>DMIT 222 - Catalogue Project: Admin Login</title>
<link rel="stylesheet" type="text/css" href="../styles/divs.css" />
<link rel="stylesheet" type="text/css" href="../styles/fonts.css" />
<link rel="stylesheet" type="text/css" href="../styles/tags.css" />
<link rel="stylesheet" type="text/css" href="../styles/tables.css" />
<link rel="stylesheet" type="text/css" href="styles/forms.css" />
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="../scripts/loginFormValidation.js"></script>
</head>
<body>
<div id="wrapper">
<header>
<h1>Ship Catalogue</h1>
</header>
<div id="mainContent">
<form id="LoginForm" name="LoginForm" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<div class="FormRow"><label for="Username">Username:</label><input type="text" name="Username" id="Username" /><p id="userErrors"><?php echo $userErrors; ?></p></div>
<div class="FormRow"><label for="Password">Password:</label><input type="password" name="Password" id="Password" /><p id="passwordErrors"><?php echo $passwordErrors; ?></p></div>
<div class="FormRow"><input type="submit" name="Submit" value="Login!" /></div>
</form>
</div>
<footer>
<a href="http://www.logicanddesign.ca/">Site Developed by Logic & Design</a>
</footer>
</div>
</body>
</html>
这是 loginFormValidation.js 脚本:
$("#Username").blur(function(e){
alert();
if ($("#Username").val() == "") {
$("#userErrors").text("Username must be entered!");
}
});
$("#Password").blur(function(e){
if ($("#Password").val() == "") {
$("#passwordErrors").text("Password must be entered!");
}
});
