Why Doesn't jQuery's `trigger('click')` Work on Hidden File Inputs, and How Can I Fix It?

Triggering File Input with jQuery

In an attempt to activate a file input field through jQuery, a user encountered an issue when the standard syntax of $('#fileinput').trigger('click'); proved ineffective.

Initially, it was assumed that a security restriction was causing the issue. However, further investigation revealed that the problem occurred specifically when the file input field was hidden through display:none; or visibility:hidden;. To circumvent this restriction, a simple positioning solution was employed:

position: absolute;
top: -100px;

By placing the file input field outside the viewport, the security restriction was effectively bypassed, and the trigger function worked as intended.

As noted in a related discussion, this approach can be considered a useful workaround or a hack, depending on one's perspective. Nonetheless, it provides a practical solution to a commonly encountered problem in triggering file input fields using jQuery.
