Hello Readers,
is() is the jquery method which is used to checks or matches the selector to selectorElement. It returns a boolean value indicating true or false.
Syntax :
$(selector).is(selectorElement,function(index,element))
Parameter :
selectorElement : It is a required parameter which specifies a selector element to match the current set of elements against selectorElement. It returns true if there is at least one match and false if not.
function(index,element) : It is a Optional parameter which specifies a function to run for the group of selected elements.
index - index used for the index position of the element.
element - element used for the current element.
Code Example :
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("p").click(function(){
if ($("p").parent().is("div")) {
alert("Parent of p is div");
}
});
});
</script>
</head>
<body>
<div>
<p>Click me</p>
</div>

In the above code when we click of paragraph p tag we show the alert message if we find out paragraph p tag selector parents is div.
