Check if element exists in jQuery [duplicate]

Question

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

Answer 1

$('elemId').length doesn't work for me.

You need to put # before element id:

$('#elemId').length ---^

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.

Answer 2

Try to check the length of the selector, if it returns you something then the element must exists else not.

 if( $('#selector').length )         // use this if you are using id to check {      // it exists }    if( $('.selector').length )         // use this if you are using class to check {      // it exists }
