tec*_*dog 7 popup sendmessage google-chrome-extension
我正在尝试为chrome扩展程序创建一个弹出界面.我似乎无法从popup.html/popup.js向content.js脚本发送消息.这是我到目前为止所拥有的.当我点击扩展图标时,我会看到一个说clickme的按钮.我点击它没有任何反应,chrome javascript控制台没有错误,也没有发送到content.js的消息.

我修改了您的用户popup.js并将DOMContentLoadedChrome扩展用作:
popup.js:
function popup() {
chrome.tabs.query({currentWindow: true, active: true}, function (tabs){
var activeTab = tabs[0];
chrome.tabs.sendMessage(activeTab.id, {"message": "start"});
});
}
document.addEventListener("DOMContentLoaded", function() {
document.getElementById("button1").addEventListener("click", popup);
});
content.js:
chrome.runtime.onMessage.addListener(
function(request, sender, sendResponse) {
if( request.message === "start" ) {
start();
}
}
);
function start(){
alert("started");
}
popup.html:
<!DOCTYPE html>
<html>
<head></head>
<script src="popup.js"></script>
<body>
<input id="button1" type=button value=clickme>
</body></html>
我已经测试了我的结果它的工作原理.
