How come the equation in the title is false? How do check if two jQuery selectors point to the same DOM object?
You are comparing two distinct jQuery objects because you call
$() twice (once for each side of the equation), and as MooGoo explains jQuery creates new wrapper objects for each time you call it. That's why the comparison ends up returning false.
You can extract a DOM object from each jQuery object by either using
get() or array dereferencing, then compare these elements. The following both return true because both identical selectors match the same
body DOM element:
$('body').get(0) == $('body').get(0) $('body') == $('body')
If you want to test against a jQuery selector, use
is(). Note that, unless your selectors are identical, the selectors you use may not necessarily match the same DOM elements (it's still better to use the above). This also returns true:
