I have the following HTML and Javascript in a page that should display "TEXT" in the body and alert me with "alert!" However, it only displays "TEXT"; my Javascript console says "msg is undefined."
<html>
<head>
<script type="test/javascript">
function msg() {
alert("alert!");
}
</script>
</head>
<body>
<p>
<script type="text/javascript">
document.write('TEXT');
msg();
</script>
</p>
</body>
</html>
If that's a direct copy/paste, then your problem appears to be a type:
<script type="test/javascript">
You have test there instead of text
<script type="test/javascript">
You have a typo here. It should say "te**x**t/javascript". It is not parsing correctly in the current state.
you have a typo:
<script type="test/javascript">
should be
<script type="text/javascript">
As so many others have pointed out, the type attribute of the script tag is wrong; it should be "text/javascript". To avoid this in the future, you can leave off the type attribute altogether as browsers will default to "text/javascript" unless otherwise specified.
