What does this jQuery mean?

Question

   $("#element").get(0).value =  v;

Answer 1

Get the first DOMElement that matches this query (similarly getElementById('element').value = v). Really bad jQuery style.

$("#element").val(v); could be used to make it more jQuery-ish and independent of input type.

Answer 2

It is true that using your own properties available in DOM elements, instead of jQuery methods.

With get() ^(docs), you extract the DOM element from the jQuery object, and then valueset your new value using your own property .

The equivalent that I would prefer to use would be:

$("#element")[0].value =  v;

... that would do the exact same thing, but do it directly through the index of the DOM element.
