Capital letters

Hello,

is it possible to have JavaScript divide a word, based on Capital Letters.
Say the word "HelloWorld" is written into a file. JavaScript would then divide it into the two words "Hello World" ?

If it is possible, could you show me how.

Thank you, Marringi

Try this:

Code:

var separated = "HelloWorld".replace(/(\S)([A-Z])/g, "$1 $2");

Thank you for the answer. Could you also show me how you would use it with "document.write" ?

Thank you

Document.write should only be used as the page is being loaded (parsed), otherwise it will overwrite the page, hopefully you understand this. Assuming that you do, you could do:

Code:

var separated = "HelloWorld".replace(/(\S)([A-Z])/g, "$1 $2");
document.write(separated);

In place of "HelloWorld" in the above, you could use any variable containing a string value:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

</head>
<body>
<script type="text/javascript">
var bob='NannyMcFee';
var separated = bob.replace(/(\S)([A-Z])/g, "$1 $2");
document.write(separated);
</script>
</body>
</html>

Which also demonstrates that this is not always the optimal way to parse a string with no spaces.
