在新标签中执行内容脚本 - chrome extentions

Jam*_*mer 1 html javascript google-chrome google-chrome-extension

我正在尝试创建一个chrome扩展程序,它会从特定网站上删除一些内容,然后打开一个新选项卡,并对已删除的数据进行处理.

下面是我做的一个测试,看看我怎么做.不幸的是,我似乎无法执行该newtab-script.js文件,因为我收到此错误:

运行tabs.executeScript时未经检查的runtime.lastError:无法访问url"chrome-extension://FAKEIDgfdsgfdsgfdsgdsgfdsgFAKEID/newpage.html"的内容.扩展清单必须请求访问此主机的权限.at Object.callback(chrome-extension://FAKEIDgfdsgfdsgfdsgdsgfdsgFAKEID/background.js:43:25)

websitescrape.js

var button = document.createElement("button");
button.classList.add("web-scrape");
button.innerHTML = "scrape web";
document.querySelector('.placeIWantToPutButton').appendChild(button);

button.addEventListener('click', scrapeData);

function scrapeData(){
    //do website scraping stuff here...
    var fakedata = [{test:"data1"},{test:"data2"}];

    //send scraped data to background.js
    chrome.runtime.sendMessage({setdata: fakedata}, function(tab){
        //callback
    });

原因:无法使用chrome-extension://scheme 将内容脚本注入扩展页.

解决方案:由于您可以控制该html页面,因此只需显式引用内容脚本文件即可.

newpage.html:

        <script src="newtab-script.js"></script>
    </body>
</html>

并且不要使用executeScript.
