Question

For example I have a function that has one argument, it can be DOM element ID or className.
How can I select only first element wrapped with jQuery?

$(value).get(0) and $(value)[0] returns just the plain DOM element, not a jQuery wrapped element.

Answer 1

$(value).eq(0);
// or
$(value).first();
// or
$(value + ':eq(0)');
// or
$(value + ':first');
