Strip all non-alphabetical chars via JS?

[lkalisky]

Hi,

I would like to take this string:

 [Sports & Fitness] > General

and make it into:

 Sports+Fitness+General

Can someone help with doing this via JS?

Thanks!

var str="[Sports & Fitness] > General"
str.replace(/\W+/g,"+");

Hi there lkalisky,

note that \W will not remove numerals or underscores.
If you want them removed and do not want more than one "+" between words or a "+" at the beginning or end of the string, then try it like this...

<script type="text/javascript">
var strings=[
 '[Sports & Fitness] > General',
 '<Webmaster>World{Forums} Rock@~',
 '*&^Bird087__987brain(0#@"'
 ];
for(c=0;c<strings.length;c++) {
strings[c]=strings[c].replace(/\W[red]¦[/red]\d[red]¦[/red]\_/g,'+').replace(/\+{2,}/g,'+').replace(/^(\+)[red]¦[/red](\+)$/g,'');
alert(strings[c]);
}
</script>

Note:- The l symbol above the backward slash on the keyboard is changed to ¦ by Webmaster World Forums. :(
I do not know the reason for this idiosyncrasy. ;)
So make sure that the three used in the script-(highlighted in red)- are replaced with the correct symbol.

I would use a regex, but much simpler.

Note, this would work in Perl, I do use Regex in JS but some things are different, so please test this and let me know.

var str = "[Sports & Fitness] > General"; 
var newstr = str.replace( /[^a-zA-Z]/, " "); // Replace any non letters with a space 
var newerstr = newstr.replace( /\s+/, "+"); // Replace one or more spaces, with just a +
