This is one of the tricky jQuery question on Interviews. This is a basic question, but don’t expect every jQuery beginner to know about this. You can use the following jQuery selector to retrieve all the selected options of <select> tag with multiple=true :

$('[name=NameOfSelectedTag] :selected')

This code uses the attribute selector in combination of :selected selector, which returns only selected options. You can tweak this and instead of name, you can even use id attribute to retrieve

<select> tag.
