How to get the html element id if user pressed enter inside textarea

Question

There is much more code, but I will only show one function here:

$(window).keydown(function(event){
    if(event.keyCode == 13) {
        event.preventDefault();

        // how to check if a user pressed enter inside a specific
        // textarea box 
    }
});

Actually what I want to know is, is the specific element in focus or not!

You can simply check if your textarea is focused using the jQuery :focus selector :

$(window).keydown(function(event){
    if(event.keyCode == 13) {
        event.preventDefault();

        if($('#yourTextarea').is(':focus')){
            //...
        }
    }
});
