I want to simulate a Keypress event using the Javascript Console. I see lots of answers using an input element. I don't want to use an input element. I just want to paste some code into the Javascript console and have a keypress event simulated(specifically the back space button).
Answers using jQuery are welcome.

We use event handlers to simulate keypress events in JavaScript. An event in JavaScript, as the name suggests, refers to actions taken by the browser or user.
The answer is: There is no way to programmatically trigger input keys in the sandboxed browser environment under normal circumstances.
To simulate native-language keystrokes, you can also use the [Xnn] or [Dnn] constants in the string passed to the Keys method. nn specifies the virtual-key code of the key to be “pressed”. For instance, [X221]u[X221]e will “type” the u and e characters with the circumflex accent.
JavaScript keyboard eventskeydown : Keydown happens when the key is pressed down, and auto repeats if the key is pressed down for long. keypress : This event is fired when an alphabetic, numeric, or punctuation key is pressed down. keyup : Keyup happens when the key is released.
jQuery has a .keypress method accepting no arguments that simulates a keypress.
$("#target").keypress();
Will trigger a keypress on #target
If you'd like to also select which key was pressed, you can use .trigger. This example is from the docs:
var e = $.Event("keydown", { keyCode: 8}); //"keydown" if that's what you're doing
$("body").trigger(e);
The key code 8 is the key code for backspace in JavaScript.
Let me know how that works for you :)
