string function replace help

[gingerj]

Hi I'm trying to replace commas in a string with spaces, it works for the first instance of a commas. but I dont know how to remove the rest:

var aString = "Humpty,Dumpty,sat,on,a,wall";
document.write(aString.replace(","," "));

[jscheuer1]

var aString = "Humpty,Dumpty,sat,on,a,wall";
document.write(aString.replace(/,/g, ' '));

The g means 'global'
