recognize a character in input field

[manuel alarcon]

Hi there. A friend of mine needs to know (me too, indeed) how to do this:

she has an app where do a little math: sum 1.5+1.3=2.5

but, she wants 2,5 as a correct answer too...in fact, any value whith a comma in it... i think the . has to be recognized and changed to , or viceversa...but we dont know the syntax...

can anybody help?

thanks, greetings from chile

this will do it:

String.prototype.replace = function(s,r) {
//s is the substring you're looking for
//r is what you want to replace it with
var a = this.split(s);
return a.join(r);
}

myDodgyNum = "2,5";
myNiceNum = myDodgyNum.replace(',','.');

surprisingly fast....and accurate...it worked perfectly. thanks
