从 Javascript 控制台模拟按键事件

问题描述

我想使用 Javascript 控制台模拟 Keypress 事件.我看到很多使用输入元素的答案.我不想使用输入元素.我只想将一些代码粘贴到 Javascript 控制台中并模拟一个按键事件(特别是退格按钮).

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).

欢迎使用 jQuery 回答.

Answers using jQuery are welcome.

推荐答案

jQuery 有一个 .keypress 方法不接受模拟按键的参数.

jQuery has a .keypress method accepting no arguments that simulates a keypress.

$("#target").keypress();

将触发 #target

如果您还想选择按下哪个键，您可以使用 .trigger.这个例子来自 docs:

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);

键码 8 是 JavaScript 中的 退格键码.

The key code 8 is the key code for backspace in JavaScript.

让我知道这对你有什么作用:)

Let me know how that works for you :)
