How to Trigger File Input with jQuery Without Violating Security Restrictions?

Triggering File Input with jQuery

jQuery offers a convenient way to interact with HTML elements, but triggering the native file input can be challenging due to security limitations.

Solution:

The key to bypassing this restriction is to ensure the file input is visible outside the viewport. One method that has proven effective is to use absolute positioning and place the file input above or below the viewport.

For example, the following code positions the file input 100 pixels above the viewport, allowing it to be triggered without violating security restrictions:

$('#fileinput').css({
  position: 'absolute',
  top: '-100px'
});
$('#fileinput').trigger('click');
Copy after login

Demonstration:

You can see a working example of this approach at [jsfiddle.net/DSARd/1/](http://jsfiddle.net/DSARd/1/).

Note:

While this method effectively triggers the file input, it can be considered a hack. It is recommended to only use it when absolutely necessary.
