I am trying to learn javascript/jquery, using firebug to debug and have built a page, which I have reduced to a minimal below:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="jquery-1.3.2.js" type="text/javascript"></script>
<script language="JavaScript" "text/javascript">
function geoAddress() {
alert("start");
var postcode = $("#PostCode").val();
}
</script>
<title>Postcode</title>
</head>
<body>
<div class="page">
<h2>Create</h2>
<form action="/Venues/Create" method="post">
<fieldset>
<p>
<label for="PostCode">Postcode:</label>
<input id="PostCode" name="PostCode" type="text" value="" />
<input type="button" onclick="geoAddress();"/>
</p>
</fieldset>
</form>
</div>
</body>
</html>
I believe that this worked previously, but now although it does work (i.e. I press the button and get an alert) in firebug, on first loading I see a javascript error.
I have jquery-1.3.2.js loaded in the same directory as my file.
I seem to be struggling with firebug so would appreciate pointing in the direction of tutorials for the current version for javascript debugging. I can't even see a way to view the whole error message.
I would appreciate any help with what this error is and also pointers in the right direction for using firebug.
