Call function from another jQuery

Question

    $(document).keydown(function(e){
        if (e.keyCode == 37) { 
            return false;
        }
    });

    $(".direction").click(function() {
        var direction = $(this).text();

When I click on a button with .direction class the second function above is called. When the left key is pressed I want to call the $(".direction").click(function() { But with a value (Instead of the var direction = $(this).text(); part) It would be var direction = value passed to function;

How can I do that?

Answer 1

Add another function that is used by both methods:

$(document).keydown(function(e){
     if (e.keyCode == 37) { 
          move("left");
     }
});

$(".direction").click(function() {
     move($(this).text());
});

function move(newDirection)
{
     var direction = newDirection;
}
