In this video we will discuss the jQuery :checked selector.

The :checked selector selects all checked checkboxes or radio buttons. Let us understand this with an example.

Selects all checked radio button elements
$('input[type="radio"]:checked')

Example : When you click the submit button without selecting any radio button, "No radio button checked" message should be displayed.

When you click the submit button after a radio button is checked, then a message stating "Male is checked" or "Female is checked" should be displayed.

Replace ﹤ with LESSTHAN symbol and ﹥ with GREATERTHAN symbol.
