How can we capture ALT255 Character

Hi All

When we Type while Pressing ALT, 255, then we get a special character like Space(" "). How can we capture this character with JavaScript.

Thanks

<input type=text name=txt>
<button onclick="for (i=0; i<txt.value.length; i++) if (txt.value.charAt(i) == ' ') alert('255 found'); else alert('OK');"

... txt.value.charAt(i) == ' ' ...
this here is typed by using ALT+255

Hi Venci75

I have checked both ways but it is not handling it, since it is not a simple BLANK space ' '. So Please tell me if any other way out is there..


Thanks

ok - you can then try something like this:

<input type=text name=txt>

<button onclick="if (txt.value.indexOf(String.fromCharCode(<code>)) >=0) alert('255 found'); else alert('OK');">

but this won't work in all cases. You must check what is the code of the 255 character in ISO-Latin-1 codeset.

on my computer it is 160 - so this should be:
... String.fromCharCode(160) ...


btw: the previous suggestion will work if you type in ALT+255 where you think it is space
