如何通过单击 Javascript 的按钮来模拟按键？
[英]How to simulate keypress with a button click on Javascript?
问题描述
I am currently working on a calculator and wondered if there is a way to link keypresses to buttons so when I click a button, it simuliates the key being pressed and sends that info to the textbox.
我目前正在研究一个计算器，想知道是否有办法将按键链接到按钮，所以当我单击一个按钮时，它会模拟按下的键并将该信息发送到文本框。
When I google, all the info I get is enabling buttons by keypresses but not the other way around.当我用谷歌搜索时，我得到的所有信息都是通过按键启用按钮，而不是相反。
If someone could help me cause my code is already a mess with all the conversations and keypress events.如果有人可以帮助我，因为我的代码已经被所有的对话和按键事件弄得一团糟。

I believe this is answered in this Stackoverflow thread: Is it possible to simulate key press events programmatically?我相信这个 Stackoverflow 线程已经回答了这个问题： 是否可以通过编程方式模拟按键事件？ . .
To add it to the textbox you can listen to the keydown event and add the character accordingly.要将其添加到文本框中，您可以监听 keydown 事件并相应地添加字符。
