[英]Console.log not showing in console when in listener
I'm new to javascript so I apologies if this is obvious and everyone knows.我是 javascript 的新手,所以如果这很明显并且每个人都知道,我很抱歉。
I'm using Message Passing to intruct the background.js of my Chrome Extension to perform an action when you press a button in the extensions popup.js当您按下扩展程序 popup.js 中的按钮时,我正在使用消息传递来指导我的 Chrome 扩展程序的 background.js 执行操作
popup.js: popup.js:
getCurrentTab(function(tab) {
chrome.runtime.sendMessage(
{type: 'status', tabId: tab.id },
function(response) {
console.log(response.message)
}
)
})
Background.js:背景.js:
chrome.runtime.onMessage.addListener(
function(message, sender, callback) {
console.log("Received message" + message + ", " + sender + "," + callback)
alert('received')
callback({message: message.type});
})
I've already learned that i need to "Inspect" my popup window for it's console (where I can see the response being printed).我已经了解到我需要“检查”我的弹出窗口 window 的控制台(我可以看到正在打印的响应)。
I can see the page is alerting, and I can see the response in my popups console.我可以看到页面正在发出警报,并且我可以在弹出窗口控制台中看到响应。 But the main pages console isn't being filled (with message starting "Received message").但是主页控制台没有被填充(消息以“收到的消息”开头)。
Can someone help a poor js beginner out?有人可以帮助一个可怜的 js 初学者吗?
