Check if div with class name exists using jQuery

If you want to check if a div with a specific class name exists using jQuery, you can use the `length` property. This property returns the number of elements that match a selector, so if the length is greater than 0, it means that the element exists.

Here's an example code snippet:

if ($('.your-class-name').length) {
  // Do something if the div exists
} else {
  // Do something else if the div doesn't exist
}

In this code, replace `'your-class-name'` with the actual name of the class you want to check for.

This method is useful if you want to conditionally execute code based on whether or not a certain element exists on the page. By using jQuery's `length` property, you can easily check for the presence of an element and take appropriate action.
