Check if element exists in jQuery [duplicate]

How do I check if an element exists if the element is created by .append() method?
$('elemId').length doesn’t work for me.


$('elemId').length doesn’t work for

You need to put # before element id:


With vanilla JavaScript, you don’t need the hash (#) e.g. document.getElementById('id_here') , however when using jQuery, you do need to put hash to target elements based on id just like CSS.
