How to test if a script load succeeded/failed?
I've got a sample script as below. I wanna see if local.js or online/latest.js failed to load. Is it possible?
<html>
<title>My JQuery Test</title>
<head>
<!--<script type="text/javascript" src="jquery/jquery.local.js"></script>-->
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$("#Buttons-theTestAlert").click(function () {
alert("`Test Alert` clicked");
});
});
</script&开发者_运维技巧gt;
</head>
<body>
<button id="Buttons-theTestAlert">Test Alert</button>
</body>
</html>
You can test
if (myFunction) myFunction()
else alert('not loaded (yet)')
加载中,请稍侯......
