背景見上一篇博客修改網(wǎng)頁內(nèi)容的方法
上一篇博客之后，我要修改的網(wǎng)頁有一個(gè)新改版，然后有個(gè)數(shù)據(jù)存在了window中，我直接在js中使用window.xxx發(fā)現(xiàn)無法獲取。所以有本文。

https://onelinerhub.com/chrome-extension/window_object#:~:text=chrome-extension%20How%20to%20access%20or%20modify%20window%20object,%3D%20%27console.log%20%28window%29%3B%27%3B%20%28document.head%7C%7Cdocument.documentElement%29.appendChild%20%28script%29%3B%20ctrl%20%2B%20c

搜了一下發(fā)現(xiàn)有兩種方法，如上，大概就是：

方法1

var script = document.createElement('script');
script.textContent = 'console.log(window);';
(document.head||document.documentElement).appendChild(script);

出現(xiàn)報(bào)錯(cuò)：

extensions_version_page.js:6 Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' 'wasm-unsafe-eval' 'inline-speculation-rules' http://localhost:* http://127.0.0.1:*". Either the 'unsafe-inline' keyword, a hash ('sha256-XnQUOdrKm+cYqdkT/ljnkhjaYaitt2Xh3uRQxH/M9z0='), or a nonce ('nonce-...') is required to enable inline execution.

方法2

{
  "name": "yeshen_extresion",
  "version": "1.0",
  "description": "yeshen test",
  "manifest_version": 3,
  "web_accessible_resource": [
    {
      "resources": [
        "assets/*",
        "js/contentScript.js"
      ]
    }
  ],
  "content_scripts": [

      ],
      "js": [

      ],
      "run_at": "document_start"
    },
  ]
}

報(bào)錯(cuò)比較清晰，就是注入的代碼和原有代碼不在一個(gè)域下，無法操作/注入javascript對象。

最后我是這樣做的：

我的方法一

從其他頁面獲取這個(gè)數(shù)據(jù)，在url參數(shù)中攜帶這個(gè)信息；

我的方法二

從dom節(jié)點(diǎn)中獲取第一個(gè)元素信息，然后通過網(wǎng)絡(luò)請求，重新請求需要的數(shù)據(jù)。文章來源地址http://www.zghlxwxcb.cn/news/detail-698353.html
