alert()一旦div加载,我试图让一个非常简单的弹出窗口.不幸的是它不起作用,我无法弄清楚为什么.
这是代码:
<html>
<head>
<title>My Site</title>
<link rel="stylesheet" type="text/css" href="style2.css">
<script type="text/javascript" src="js/jquery_1.4.2.js"></script>
<script type="text/javascript" src="js/alertjs.js"></script>
</head>
<body>
<div id="background_logo" onload="pop_alert();">
<img src="mysiteLogo.png">
</div>
<div id="signup">
<p id="instruction"> Get on board! </br> Enter your email to receive updates:</p>
<script type="text/javascript" src="js/form-validation.js"></script>
</div>
</body>
</html>
而JavaScript就是这样的:
function pop_alert(){
alert("This is an alert");
}

它不能用于div标签.以下列表可用于:
<body>, <frame>, <frameset>, <iframe>, <img>, <input type="image">,
<link>, <script>, <style>

你不能附加onload到div.试着把它放在<body>:
<body onload="pop_alert();">
