[jquery] How to destroy a DOM element with jQuery?

Suppose the jQuery object is $target.

Not sure if it's just me, but using .remove() doesn't seem to work if you are selecting by an id.

Ex: $("#my-element").remove();

I had to use the element's class instead, or nothing happened.

Ex: $(".my-element").remove();

You are looking for the .remove() function.

If you want to completely destroy the target, you have a couple of options. First you can remove the object from the DOM as described above...

console.log($target);   // jQuery object
$target.remove();       // remove target from the DOM
console.log($target);   // $target still exists

Option 1 - Then replace target with an empty jQuery object (jQuery 1.4+)

$target = $();
console.log($target);   // empty jQuery object

Option 2 - Or delete the property entirely (will cause an error if you reference it elsewhere)

delete $target;
console.log($target);   // error: $target is not defined
