如何禁用Chrome警报通知? [英] How to disable chrome alert notification?

问题描述

我需要通过我的扩展程序关闭警报通知.警报功能是javascript的内置函数，我在内容脚本中像下面一样覆盖了它，但仍然可以使用.

I need to turn alert notification off by my extension. The alert function is a javascript built-in function and i override it like below in content script but it still works.

内容脚本:

window.alert = function(){}

它不会关闭它.这个问题确实很简单，但是它不起作用，我快要疯了:)

It does not turn it off. The problem is realy simple but it does not work and i am going crazy :)

manifest.json:

manifest.json:

"content_scripts": [
    {
      "js": [ "assets/js/jquery-1.12.4.min.js", "assets/js/common.js", "assets/js/handlers.js" ],
      "matches": [ "http://*/*", "https://*/*" ],
      "run_at": "document_start"
    }
  ],

handler.js:

handler.js:

window.alert = function (msg) {
    debugger;
    console.log(msg);
}

推荐答案

您无法在Chrome中全局关闭通知(至少不是那样).

You can't switch off notifications globally in Chrome (at least, not that way).

这样做

window.alert = function(){}

您只需为自己的扩展名(=您自己的window上下文)关闭通知.出于安全原因，您不能在全球范围内执行此操作(请考虑一下如果可能的话，恶意扩展会做什么).

you simply switch off notifications for your own extension (= your own window context). You can't do this globally for security reasons (think what malicious extension could do if this was possible).

您实际上可以将您的代码注入到内容页面中；但这仍然不是您要寻求的全球"变化.如果您仍然想要这样做，那么:

you actually can inject your code into the content pages; but this is still not a "global" change that you seek. If you still want this, then:

manifest.js您的扩展程序:

{
    "name": "MyExtension",
    ...
    "permissions": ["tabs", "http://*/*"],
    "content_scripts" : [{
        "js" : ["script.js"]
    }]
}

和您的script.js:

window.alert = function(){}
