How do I find if an element contains a specific class?
if ($('#myElement').has('.myClass')) {
   do work son
}

<div id="myElement">
    <img>
    <span>something</span>
    <span class="myClass">Hello</span>
</div>

if($('#myElement .myClass')).length > 0)

if($('#myElement > .myClass')).length > 0)

if($('#myElement').find('.myClass').length > 0)

if($('#myElement').children('.myClass').length > 0)

if($('#myElement').children('.myClass').length) {
    // Do what you need to
}

if($('#myElement').children('.myClass').length > 0) {
    // Do what you need to
}

var element = document.getElementById("myElement");

var hasClass = recursivelyWalk(element.childNodes, function hasClass(node) {
  return node.classList.contains("myClass");
});

function recursivelyWalk(nodes, cb) {
    for (var i = 0, len = nodes.length; i < len; i++) {
        var node = nodes[i];
        var ret = cb(node);
        if (ret) {
            return ret;
        }
        if (node.childNodes && node.childNodes.length) {
            var ret = recursivelyWalk(node.childNodes, cb);
            if (ret) {
                return ret;
            }
        }
    }
}

if($.contains($('#myElement'), $('.myClass'))){
    alert("True");
}
else{alert("False")};
