我想通过浏览器操作按钮打开它时更新popup.html中的html.popup.js应该向当前选项卡上运行的内容脚本发送消息,并且应该收到响应并更新html.但是,内容脚本不会收到任何消息,因此不会发送正确的响应.
Content.js
var text = "hello";
chrome.runtime.onMessage.addListener(
function(message, sender, sendResponse) {
switch(message.type) {
case "getText":
sendResponse(text);
break;
}
}
);
Popup.js
chrome.tabs.getCurrent(function(tab){
chrome.tabs.sendMessage(tab.id, {type:"getText"}, function(response){
alert(response)
$("#text").text(response);
});
});
的manifest.json
{
"manifest_version": 2,
"name": "It's Just A Name",
"description": "This extension is able to",
"version": "1.0",
"permissions" : ["tabs"],
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html",
"default_title": "Click here!"
},
"content_scripts": [
{
"matches": ["https://*/*"],
"js": ["jquery.min.js","content.js"]
}]
}
Popup.html
<!doctype html>
<html>
<head>
<title>Title</title>
<style>
body {
font-family: "Segoe UI", …
