Simulating a Keypress Event from Javascript Console

问题

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.

回答1:

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 :)
