Check if a div does NOT exist with javascript

Question

Checking if a div exists is fairly simple  if document getif document getElementById  if          But how can I check if a div with the given id does not exist

User · Answer

Try getting the element with the ID and check if the return value is null:

document.getElementById('some_nonexistent_id') === null

If you're using jQuery, you can do:

$('#some_nonexistent_id').length === 0

There s an even better solution  You don t even need to check if the element returns null  You can simply do this   if  document getElementById  elementId        console log  exists       That code will only log exists to console if the element actually exists in the DOM

if   document getElementById  given-id        It does not exist     The statement document getElementById  given-id   returns null if an element with given-id doesn t exist  and null is falsy meaning that it translates to false when evaluated in an if-statement   other falsy values
