Question

So say I have this ..

  keyup_handler: function(e, item){
    if (e.which == 27) {
      close_lightbox(item);
      return false;       
    };
  }

$(document).live('keyup', function(e){ keyup_handler(e, item) });

This is not returning any console.log()’s I place in here. So I assume that that it’s not being touched. What am I missing? How do I pass the e or event to keyup_handler?

jQuery 1.4.4

Answer 1

You’re returning false from the call to keyup_handler, but not from the function that calls it, try doing:

$(document).live('keyup', function(e){ return keyup_handler(e, item); });

You may also need to modify keyup_handler slightly to return true; if the if statement doesn’t evaluate to true.

I’m assuming here that your very vague “doesn’t work” statement means that the usual keyup functionality isn’t prevented when you release the corresponding key.

Also, .live() is a deprecated jQuery function, and isn’t really intended for what you’re using it for. Use .on() (if you’re using jQuery 1.7+) or .bind() otherwise.
