How Can I Reliably Trigger a File Input with jQuery?

Triggering File Input with jQuery

Triggering an upload browse button using jQuery can sometimes be challenging. One common method involves using the 'trigger('click')' function.

When employing this method, you might encounter a security restriction that prevents it from working. This restriction occurs when the file input element has its display property set to 'none' or its visibility to 'hidden.'

To circumvent this issue, you can position the file input element outside the viewport using the following styles:

position: absolute;
top: -100px;

This method effectively removes the element from view without affecting its functionality.

By positioning the file input element outside the viewport, you can successfully trigger the browse button using jQuery. This workaround is considered a "hack" but effectively solves the problem.
