我正在尝试在新选项卡监听器的另一个外部页面内执行一些脚本。
背景.js
function onCreatedChrome(){
chrome.tabs.onCreated.addListener(function(tab) {
if (tab.url.indexOf("chrome-devtools://") == -1) {
localStorage.setItem("tabid", tab.id);
chrome.tabs.executeScript(tab.id, {code: "alert('Hello World')"}, function() {
if (chrome.runtime.lastError) {
localStorage.setItem("Error", chrome.runtime.lastError.message);
console.error(chrome.runtime.lastError.message);
}
else{
localStorage.setItem("Else case", "This should work")
}
});
}
});
}
function createTab(){
return function(){
var url = "https://www.yahoo.com/";
chrome.tabs.create({ url: url });
}
}
$(document).ready(function(){
onCreatedChrome();
$("#button").click(createTab());
});
清单.json

索引.html

<body>
<button id="button">Click Me</button>

<script type="text/javascript" src="jquery.js"></script>

我想要alert('Hello World')被注入到 Yahoo! 的主页（这只是我在另一个扩展中尝试做的一个例子）
