disable click while fadeOut delay

disable click while fadeOut delay

I'm writing a little game and have to turn off the click function temporarely:
  1. $('.drag').click(function(){
        $(this).children().show();
        var myID = $(this).attr('id');
        tempArray.push(myID);
        if(tempArray.length == 2){ // turn click off

            $('.drag').children().delay(1000).fadeOut(100); // after fading out turn click on again
            tempArray.length = 0;
        }   
    })
During the 1 second of the delay, clicking on class ('.drag) should be turned off.
After the delay the same click function should be turned on.
Thanks in advance, Henk
