jquery add function doesn't work as expected
The following snippet doesn't work.
var empty = $(); var divs = $("div"); empty.add(divs);
There is a div element in the HTML and it is added correctly to divs. But the divs collection is not added to the empty jquery object. Any ideas what`s wrong with that?
.add won't change the original object. Try:
empty = empty.add(divs);
You can do
var empty = $.extend($(), $('div'));
Per Jquery doc,
The following will not save the added elements, because the .add() method creates a new set and leaves the original set in pdiv unchanged:
var pdiv = $("p"); pdiv.add("div"); // WRONG, pdiv will not change
