Splitting an array

Copy linkTweet thisAlerts:
Apr 06.2009

I thought I understood how to split an array. But, it seems that once I split it, and I want to replace each comma with a line break, that it only works for the first comma.

[CODE]var arr_errors = new Array();
arr_errors.push(‘Test1’);
arr_errors.push(‘Test2’);
arr_errors.push(‘Test3’);
arr_errors.push(‘Test4’);
var test = arr_errors.toString().replace(‘,’, ‘n’)
alert(test);[/CODE]

Why is it only replacing the first comma?

[CODE].replace(/,/g, 'n');[/CODE]

@astupidnameApr 06.2009 — You are not actually doing a split, but converting to string, and instead of doing toString().replace(/,/g,'n')

You could use join() which converts to string with a specified delimiter between the array items:
var arr_errors = new Array();
arr_errors.push('Test1');
arr_errors.push('Test2');
arr_errors.push('Test3');
arr_errors.push('Test4');
var test = arr_errors.join("n");
alert(test);

Success!
