如何让 JavaScript execCommand("paste") 在 Electron 中工作？

Question

When the user clicks on a specific button on my screen I want to paste the content of the clipboard into a specific text field.

I currently use the code:

pasteSelectedTextFromClipboard() {
    const input = this.$refs.input as any
    input.focus()
    document.execCommand("paste")
}

When I Google I find that in Firefox it's necessary to set user_pref("capability.policy.policynames", "allowclipboard"); to allow this functionality to work. What do I have to do to get it to work in Electron?

Answer 1

Electron 为剪贴板的所有操作公开了非常好的API

Answer 2

You can useclipboard.readText() from the Electron clipboard API for this:

const { clipboard } = require("electron")

const input = document.getElementById("textbox")
input.value = clipboard.readText()

An added advantage: you will no longer need to focus the input element, as you are programmatically setting its value.

Note that this will replace all of the input's current text by what is in the clipboard.
