Hi all,
I have been tearing my hair out over the simplest of problems: document.getElementById() simply refuses to work for me. There's got to be something simple I'm missing, because I can't find anything on it.
I know the function doesn't work in all browsers, but I'm developing for IE6, so there's no problem there; but my script won't work in any browser.
Anyway, the code:
<html>
<head>
<script type="text/javascript">
<!--
function disp_toggle(id) {
id = document.getElementByID(id);
if (id.style.display = 'none') {
id.style.display = 'block';
} else if (id.style.display = 'block') {
id.style.display = 'none';
}
}
-->
</script>
</head>
<body>
<div id="disp" style="display: none;">Hidden Text</div>
<p><button onmousedown="disp_toggle('disp');">Click Me</button></p>
</body>
</html>
which yields a:
"document.getElementByID is not a function" (Firefox 1.5)
"message: Statement on line 6: Type mismatch (usually a non-object value used where an object is required)
Backtrace:
Line 6 of inline#1 script in url
id = document.getElementByID(id);" (Opera)
"Object doesn't support this property or method" (IE6)
I know there's got to be a stupid thing I'm missing, because hard-coding the div id into the getElement call doesn't work either. Thank you very much for helping.
if (id.style.display == 'none')
else if (id.style.display == 'block')

quick look:
= assigns a value
== compares a value

Yeah, but that's still not the error I'm getting. I wrote the example in about 10 seconds to show it, the only important part is the getElementByID bit.
I could even simplify the code to:
<script>
function get_id(id) {
var id = document.getElementByID(id);
}
</script>
and it'd still throw an error. Thanks for the correction, though.
getElementByID != getElementById:
var id = document.getElementById(id);
and for an easy function call:
function $() { return document.getElementById(arguments[0]); }
var obj = $('my_id');

Wow. I'm amazed...that's the fastest solution I've ever seen. Thank you. I thought javascript wasn't case sensitive, but, whatever.
