Can Special Character Keypresses Be Triggered with jQuery?

Based on previous discussions and experimentation, it appears that triggering keypress events with special characters (e.g., @, #, $) is not consistently supported.

Triggering Keypress Events with Regular Characters

To trigger keypress events for regular characters, follow these steps:

1. Create a new event object using "keydown" as the event type:

   var e = jQuery.Event("keydown");

2. Specify the key code value using the "which" property:

   e.which = 50; // # Some key code value

3. Trigger the event on the desired element:

   $("input").trigger(e);

This approach effectively triggers keypress events for regular characters.

Example Usage

To trigger a keypress event for the letter "A" with the keyCode of 65, use the following code:

var e = jQuery.Event("keydown");
e.which = 65;
$("input").trigger(e);
