Question

I have this code :

var tlTemp=new Array();

tlTemp.push("00 - 01:??:?? - TL 1");
tlTemp.push("00 - 12:??:?? - TL 2");

for(i=0; i<tlTemp.length; i++) {
    var removedTL = tlTemp[i].match(/^(\d\d) - (\?\?|10|0\d):(\?\?|[0-5]\d):(\?\?|[0-5]\d) - (.*)/);

    if(removedTL!=null) {
        alert("ok");
    }
    else
    {
        alert("no");
        return;
    }
}

and I don’t understand why first string print ok and the second (so similar) no. Why?

Answer 1

The appropriate part of the regexp that defines the different part of the string is:

(\?\?|10|0\d)

It matches:

??
10
0x   where x is a digit

So 12 does not match.

Now, also there is TL 2 instead of TL 1 but in the regexp this is defined as:

(.*)

which matches everything so that is not causing the problem.
