[RESOLVED] Regular Expression

Can somene clarify to me why does the following code:

[code]
var str = “Oranges, 12.34$, Apples, 21.15$, Bananas, 512.44$, Plums”
var regExp = /(, d+.d+.,)/g;
var myarray = str.split(regExp);
var index;

for (index in myarray)
{
document.write(myarray[index] + “<br />”);
}
[/code]

produces following output:

[b]Oranges
, 12.34$,
Apples
, 21.15$,
Bananas
, 512.44$,
Plums[/b]

while:

[code]
var regExp = /(?:, d+.d+.,)/g;
[/code]

or

[code]
var regExp = /, d+.d+.,/g;
[/code]

produces:

[b]Oranges
Apples
Bananas
Plums[/b]

I know that [B]()[/B] are capturing parentheses and [B](?:)[/B] are non-capturing one but how does this exactly apply to the code above???

Also in #JavaScript _↴
