问题描述

在chrome升级到版本74.0.3729.169(官方内部版本)(64位)后，以下代码可以正常工作并停止工作.现在，即使权限设置正确，我也会得到DOMException.如果您可以解释什么是错误和解决方法，不胜感激.异常详细信息:

Following lines of code used to work and stopped working after chrome upgrade to Version 74.0.3729.169 (Official Build) (64-bit). Now I get DOMException even though permission is set correctly. Appreciate if you can explain what is the bug and workaround. Exception details:

消息:文档未聚焦 名称:NotAllowedError 代码:0

message:Document is not focused name:NotAllowedError code:0

        navigator.permissions.query({ name: 'clipboard-read' }).then(result => {
            // If permission to read the clipboard is granted or if the user will
            // be prompted to allow it, we proceed.

            if (result.state === 'granted' || result.state === 'prompt') {
                navigator.clipboard.readText()
                    .then(text => {
                        //my code to handle paste
                    })
                    .catch(err => {
                        console.error('Failed to read clipboard contents: ', err);
                    });

推荐答案

正如Kaiido所说，您的DOM需要重点关注.在开发过程中，当我在代码中放置断点时，我遇到了同样的问题.使用相同的代码和相同的浏览器，如果关闭F12，一切都可以正常工作

As Kaiido said, your DOM need to be focused. I had the same problem during my development when i put a breakpoint in the code... The console developper took the focused and the error appear. With the same code and same browser, all work fine if F12 is closed
