Quick Reference
The is() method checks if one of the selected elements matches the selectorElement.
$('p').parent().is()
// tests if parent is a div and gives an alert
$('p').click(function() {
if ($('p').parent().is('div')) {
alert('My parent is a div');
}
});
Syntax
$(selector).is(selectorElement,function(index,element))
Note
It is generally good practice to place your jQuery code/function inside the document load function so that the action takes place ONLY after the document has finished loading. This ensures that all of the page elements that you may be selecting are in place before running the code on them.
