Remove unwanted characters from a string

Question

I want to remove the characters [ and ] inside a variable. How can I do this? My variable is something similar to this one:

var str = "[this][is][a][string]";

Any suggestion is very much appreciated!

Behold the power of regular expressions:

str = str.replace(/[\]\[]/g,'');

thank you for the quick reply! ^^.. i have an additional question though. how can i remove "[" and "]" + the string inside it except for the last string in my variable(which is "string").. im new to jQuery regular expression – unknown Nov 08 '11 at 18:35
@unknown I'm not clear on what you mean. I would suggest familiarizing yourself with regular expressions, or else just parse the string using `str.split()` to find what you want. – Blazemonger Nov 08 '11 at 18:37

the fastest way

function replaceAll(string, token, newtoken) {
    while (string.indexOf(token) != -1) {
        string = string.replace(token, newtoken);
    }
    return string;
}

All you need to do is this...

var str = "[this][is][a][string]";

srt=replaceAll(str,'[','');    //remove "["

str=replaceAll(str,']','');    //remove "]"
