我正在构建一个在页面中插入html的Google扩展程序,并在浏览器操作图标点击时显示一个菜单,当我重新加载页面时,我找不到保持扩展程序打开的方法。因此,每次重新加载时,我们都必须从“浏览器操作”图标再次激活它。
清单文件
下方{
"background": {
"scripts": ["background.js"]
},
"browser_action": {
"default_icon": "img/icone.png",
"default_title": "show menu"
},
"icons" : {
"128" : "img/icone_128.png",
"48" : "img/icone_48.png",
"32" : "img/icone_32.png",
"24" : "img/icone_24.png",
"16" : "img/icone_16.png"
},

}
],
"web_accessible_resources": [
"fonts/fontawesome-webfont.woff"
],
"permissions": [ "activeTab"]
}
脚本( background.js )注入内容脚本
chrome.browserAction.onClicked.addListener(function (tab) { //Fired when User Clicks ICON
chrome.tabs.executeScript(tab.id,
{"file": "js/contentscript.js"},
function () { // Execute your code
console.log("Script Executed .. "); // Notification on Completion
});
chrome.tabs.insertCSS(tab.id, {file: "css/grid.css"});
chrome.tabs.insertCSS(tab.id, {file: "css/font-awesome.min.css"});
chrome.tabs.insertCSS(tab.id, {file: "css/slider.css"});
});
任何帮助将不胜感激

因此,从评论中推断出问题:您的按钮单击会激活您的内容脚本,但页面重新加载会清除它。假设您希望按钮单击以充当切换:
1)始终注入内容脚本/ CSS,但不要立即显示UI:
"content_scripts": [
{
"matches": [ "<all_urls>"],
"css": ["css/grid.css", "css/font-awesome.min.css", "css/slider.css"],
"js": [
"js/jquery-1.11.1.min.js", "js/jquery-ui.js",
"js/jquery.nicefileinput.min.js", "js/contentscript.js"
]
}
],
2)跟踪“已激活”标签:
var activeTabs = {};
chrome.browserAction.onClicked.addListener( function(tab){
var active;
if(activeTabs[tab.id]){
delete activeTabs[tab.id];
active = false;
} else {
activeTabs[tab.id] = true;
active = true;
}
/* (part 3) */
});
chrome.tabs.onRemoved.addListener( function(tabId){
delete activeTabs[tabId];
});
chrome.tabs.onReplaced.addListener( function(newTabId, oldTabId){
if(activeTabs[oldTabId]) activeTabs[newTabId] = true;
delete activeTabs[oldTabId];
});
3)使用消息显示/隐藏UI:
内容脚本:
chrome.runtime.onMessage.addListener( function(message. sender, sendResponse){
if(message.showUI) showUI();
if(message.hideUI) hideUI();
});
后台脚本:
chrome.browserAction.onClicked.addListener( function (tab) {
var active;
/* (part 2) */
if(active) {
chrome.tabs.sendMessage(tab.id, {showUI: true});
} else {
chrome.tabs.sendMessage(tab.id, {hideUI: true});
}
});
可以为扩展重新加载的情况添加额外的稳健性,但这是它的要点。
