Question

For some reason, I can’t seem to find a good answer for this one.

I have been trying to escape out the caret (\^), and to use the hex, octal, and other codes for the character using \xdd, \dddd, etc…

But my replace regexp won’t replace the caret (^) with anything. It seems to simply break the expression.

Here is the code I am using:

---

var field,myExp;    

// \x5E is supposed to represent the caret in Hex...
    myExp = / *[^a-z^A-Z^0-9\s\x5E]/gi;

field = field.replace(myExp,"");
alert(field);

---

Help!

Answer 1

I found the answer, but you guys all helped me get there. Thanks!

I think what was happening was that my exlude (^) was used too many times and so was creating an exclusion of my exclusionary groups… Since there were no separators between the groups, the first one does the trick.

ORIGINAL:
repExp = / *[^a-z^A-Z^0-9]/gi;

FINAL REGEXP:
repExp = / *[^a-zA-Z0-9]/gi;

The above filters out anything that is not a leter (a-zA-Z) or number (0-9) from a string.

Thanks, people!

P.S. The space after the initial “/” is there because for some reason, Dreamweaver sees it as the beginning of a comment. 🙁
