jQuery is() Method
The is() method in jQuery is used to check whether one of the selected elements matches the value in parameter selectorEle.
Syntax
The syntax is as follows −
$(selector).is(selectorElement,func(index,element))
Above, selectorEle is a selector expression, element or jQuery object to match with the current set of the element. The func parameter is used to specify a function to run for the group of selected elements.
Example
Let us now see an example to implement the jQuery is() method −
<!DOCTYPE html> <html> <head> <style> div { width:600px; } .demo * { display: block; border: 2px solid yellow; color: blue; padding: 10px; margin: 10px; } </style> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script> <script> $(document).ready(function(){ $("button").click(function(){ if ($("span").parent().is("li")) { alert("Yes, li is a parent of span"); } }); }); </script> </head> <body class="demo">great-great-grandparent <div>great-grandparent <ul>grandparent <li>parent <span>span</span> </li> </ul> </div> <button>Check</button> </body> </html> Output
