接收端不存在:sendMessage 后台弹出
我搜索了 1 个小时的答案,但没有适合我的问题。如果这是一个常见问题,我深表歉意。所以我有一个弹出脚本必须等待来自后台的消息。但我总是收到这个错误
错误:无法建立连接。接收端不存在。
这是我的弹出窗口
$( document ).ready(function()
{
chrome.extension.getBackgroundPage().download(true, "test");
chrome.runtime.onMessage.addListener(function(request, sender, sendResponse){
console.log(request, sender, sendResponse);
});
});
,这是我的背景,它是我的 http 请求的一部分
if(this.readyState ==3 && this.status ==200)
{
chrome.tabs.query({active: true, currentWindow: true},function(tabs) {
chrome.tabs.sendMessage(tabs[0].id, "Loading", function(response) {
console.log(response);
});
});
}
,这是我的清单
`{

"version": "1.0",
"description": "first extension",
"icons":{
"16":"/images/ytDownloader_image_16.png",
"48":"/images/ytDownloader_image_48.png",
"128":"/images/ytDownloader_image_128.png"
},
"permissions": [

"tabs",
"webRequest",
"webNavigation",
"management",

],
"browser_action": {
"default_popup" :"popup.html"
},
"background":{
"scripts":["/js/jquery-3.5.1.min.js","background.js"],
"persistent": true
},
"manifest_version": 2
}`
请帮助我:)
I searched for 1 hour my answer but nothing that fits my issue. I apolagize if it was a common problem. So I have one popup script that have to wait a message from the Background. But I always get this error
Error : Could not establish connection. Receiving end does not exist.
here is my popup
$( document ).ready(function()
{
chrome.extension.getBackgroundPage().download(true, "test");
chrome.runtime.onMessage.addListener(function(request, sender, sendResponse){
console.log(request, sender, sendResponse);
});
});
and here is my background which is a part of my http request
if(this.readyState ==3 && this.status ==200)
{
chrome.tabs.query({active: true, currentWindow: true},function(tabs) {
chrome.tabs.sendMessage(tabs[0].id, "Loading", function(response) {
console.log(response);
});
});
}
and here is my manifest
`{
"name": "My extension axel",
"version": "1.0",
"description": "first extension",
"icons":{
"16":"/images/ytDownloader_image_16.png",
"48":"/images/ytDownloader_image_48.png",
"128":"/images/ytDownloader_image_128.png"
},
"permissions": [

"tabs",
"webRequest",

"management",

},
"background":{
