Stripping Characters out of Strings ?

[itsmarkdavies]

Hi, i am new to JavaScript so please accept my apologies if this is a simple question.

I need to write a Function that will take a String (entered through a TextBox on an .asp Page by a User), and strip a range of characters (e.g. "," "/" "'" "|") out of it, and replace them with nothing.

For example(s) :-

02/09/1967 should become 02091967
a,b should become ab

Any help appreciated.

Thanks,

Mark.

just pass it the string to look in, what to look for, and what to replace it with.

    function xreplace(checkMe,toberep,repwith){
        temp = checkMe;
        a = 0;


            for(i = 0; i < checkMe.length; i++){
                a = temp.indexOf(toberep);
        temp = temp.substring(0 , a) + repwith + temp.substring((a + toberep.length));


            if (a == -1){
                break;
        }

            }
            return temp;
    }

Whether you are doing this client side with JavaScript or server side with something like PHP, you might want to look at regular expressions.

They can do this and much, much more besides. The effort of getting to know how to use them will be well spent.
