Replace string in javascript array

Question

I have an array in javascript. This array has strings that contains commas (","). I want all commas to be removed from this array. Can this be done?

Can't you filter the strings before them being pushed in the array? Otherwise is just a simple for loop.
I tried to but the strings are coming from other place, dynamically. But it doesn't matter anyway, I figured out what I was doing wrong. I was leaving a comma after every db result. I was convinced that the array push I was doing was adding a comma after every push. I'm a starter in JS. Thanks anyway.

Yes.

for(var i=0; i < arr.length; i++) {
 arr[i] = arr[i].replace(/,/g, '');
}

+1 for getting closer than me but you need to do something with the result, replace does not mutate the string. – AnthonyWJones Jun 4 '09 at 21:58

Sure -- just iterate through the array and do a standard removal on each iteration.

Or if the nature of your array permits, you could first convert the array to a string, take out the commas, then convert back into an array.
