I’m trying to get an Alert if a class contains an element of a certain class.
My attempt: https://jsfiddle.net/d9qecgjx/1/
HTML
<div class="parent">
<div class = "child1">
</div>
<div class = "child2">
</div>
<div class = "child3">
</div>
<div class = "child4">
</div>
</div>
jQuery
if ( $( ".parent" ).hasClass( ".child3" ) ){
alert("You have that");
}
One approach is to use .find() - it searches descendants. so
if ( $( ".parent" ).find( ".child3" ).length ){
alert("You have that");
}
