Question

last_tag="abcde   x";
last_tag = last_tag.replace(/[\s]+x$/, '');

this is my problem: i have to remove an “x” at the end of my string. This piece of code is used in a plugin i’ve been using without problems until now. On IE 7 “last_tag” is selected in the wrong way, so i get an “x” and i have to remove it. I think who wrote the plugin added this replace to do exactly this but it’s not working on IE7.

Example:
before:last_tag=”abcde x”
after: last_tag=”abcde”

Actually the problem is that last_tag remain exactly the same.

is the regex correct? is there any error or compatibility issue with IE?

EDIT: Probably the regex is not the issue.

I’ve tried this piece of code, but nothing happens:

var temp_tag="abc x";
alert(temp_tag);
temp_tag = temp_tag.replace(/[\s]+x$/, '');
alert(temp_tag)

The same piece of code work perfectly on Chrome.

The regex looks okay, but it’s possible you’re trying to match non-breaking spaces (U+00A0). \s doesn’t match those in IE (as explained in this answer), but it does in FireFox and Chrome.
