Question

Is there a way to determine if a div element is empty using JavaScript instead of jQuery?

I need to use JavaScript, without jQuery, to determine whether an element is empty or not. If the element is empty, the code should return true; if it contains content, it should return false."

For instance, let's consider this div that needs to be checked for emptiness:

<div id="foo">

</div>

Since this div is empty, the code should return true. However, in the scenario below:

<div id="cats">
<h1>Cats are awesome!</h1>
</div>

The code should return false because this div has content.

EDIT: What I actually need to check is whether the div contains any children. The solution can be found in the comments section.

Upon further examination, I discovered a simpler solution to this issue after noticing that another user identified it as a duplicate post.

The solution involves utilizing the following code:

if(document.getElementById('foo').innerHTML.trim().length == 0) {
   <place your code here>
}

I appreciate the assistance regardless :)

If you're looking to determine if a string contains any content, you can utilize either

document.getElementById().innerHTML

or

document.querySelector().innerHTML

. Simply retrieve the string and then check for its contents.

function checkContent(selector) {
return document.querySelector(selector).innerHTML.trim().length > 0;
}

const code = document.querySelector('#code')

code.innerHTML = checkContent('#test_1');
code.innerHTML += '\n' + checkContent('#test_2');
code.innerHTML += '\n' + checkContent('#test_3');

<div id='test_1'>Some Text</div>
<div id='test_2'><p>more text here</p></div>
<div id='test_3'></div>

<pre id='code'></pre>

The outcome might be a string alteration based on how spaces are utilized in your code, enabling you to strip the content and verify if it is blank.

let text = document.querySelector("#dogs");
let output = text.innerHTML.trim();
output == "" ? console.log("The string is empty") : console.log("The string is not empty");
