[SOLVED] Regex

Hi guys,
I want to check the text input to see if it is in all caps.
This needs to be client-side not server side so I'm using JS.
I can't get it to work. My JS skills aren't that bad but I've never used regex with it.

Here's my code.

HTML: Select all

<html>
<head>
<script type="text/javascript">
function caps(str) {
    if(str.test(/[A-Z]+/)) {
    alert("Upper Case");
    }
}
</script>
</head>

<body>
<form action="">
<input type="text" onchange="caps(this)" />
</form>
</body>
</html>

Code: Select all

if(str.match(/[A-Z]+/)) {

No change unfortunately.

Working now:

HTML: Select all

<html>
<head>
<script type="text/javascript">
function caps(str) {
    if(str.match(/[A-Z]+/)) {
    alert("Upper Case");
    }
}
</script>
</head>

<body>
<form action="">
<input type="text" onchange="caps(this.value)" />
</form>
</body>
</html>
