I dynamically create a new div (with a "textbox" class and ID), and some other elements inside of it, and later on in my code I bind that div to the click event, and display the element clicked, like so:

$('#textbox_'+i).bind('click', function(event){
    alert(event.target.className);
}

This is fine, and it'll give me textbox as one of the classes displayed. But event.target.hasClass() doesn't seem to work. So, when I do the following, nothing happens:

$('#textbox_'+i).bind('click', function(event){
    if(event.target.hasClass('textbox')) { alert('got it!'); }
}

I tried it a few different ways and it appears to me that event.target.hasClass() just doesn't work. Is there another way to deal with events or am I doing something wrong?

役に立ちましたか?

You're trying to use a jQuery method, hasClass(), on a standard DOM element. You need to convert the plain JS DOM element e.target to a jQuery object, like so:

$(event.target).hasClass('textbox')

And you end up with :

$('#textbox_'+i).on('click', function(event){
     if( $(event.target).hasClass('textbox')) alert('got it!');
});

Notice the use of on(), the proper closing of the click function, and you don't need curly brackets in your if statement if you're only executing a simple alert.

If you want to keep your JS DOM element plain without using jQuery...

event.target.classList.contains('textbox')
