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 give

Answer 1

getElementById returns null if there is no such element.

Answer 2

I do below and check if id exist and execute function if exist.

var divIDVar = $('#divID').length;
if (divIDVar === 0){ 
    console.log('No DIV Exist'); 
} else{  
    FNCsomefunction(); 
}   

Answer 3

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

Answer 4

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.

Answer 5

All these answers do NOT take into account that you asked specifically about a DIV element.

document.querySelector("div#the-div-id")

@see https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector

Answer 6

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)
