javascript - Removing $() jQuery wrapper to just get raw JS element

Question

Random just out of curiosity question:

Let's say for whatever reason I get an element back from a function

$(element)

But I want to remove the $( __ ) jQuery wrapper to leave the regular DOM Element:

element

Is this possible? (I'm sure it'd be smart to test $(element).length() to make sure it isn't more than 1 thing inside beforehand too...

Answer 1

var firstElem = $(element)[0];

or

var firstElem = $(element).get(0);

Calling get() without an index gives you an array of the elements.

Reference: jQuery get()

Answer 2

DOM elements are stored as properties at numeric zero-based indices, so you access them just like you would for any other object.

$jqObj[0];

Or get a full Array of elements using toArray()

$jqObj.toArray();

Answer 3

function removeJWrapper (el) {
    console.log(el[0]);
}
