Question

How do you trim all of the text after a comma using JS?

I have: string = Doyletown, PA

I want: string = Doyletown

Answer 1

How about a split:

var string = 'Doyletown, PA';
var parts = string.split(',');
if (parts.length > 0) {
    var result = parts[0];
    alert(result); // alerts Doyletown
}
