Jquery – How to pass parameter to $.keyup() ？

jquery

I want to do something like :

function validateBody($obj)
{

}

$ojb.keyup(validateBody($ojb));

How to do it the right way?

Best Solution

This will do what you are looking for:

function validateBody(e) {
    var $obj = e.data.obj;

    // do something
}

$ojb.bind('keyup', { obj: $ojb }, validateBody);

Check out the documentation on event.data and bind

Javascript – n “exists” function for jQuery

In JavaScript, everything is 'truthy' or 'falsy', and for numbers 0 means false, everything else true. So you could write:

if ($(selector).length)

You don't need that >0 part.

Javascript – How to detect a click outside an element

Note: Using stopPropagation is something that should be avoided as it breaks normal event flow in the DOM. See this CSS Tricks article for more information. Consider using this method instead.

Attach a click event to the document body which closes the window. Attach a separate click event to the container which stops propagation to the document body.

$(window).click(function() {
  //Hide the menus if visible
});

$('#menucontainer').click(function(event){
  event.stopPropagation();
});
