【问题描述】:
我使用带有弹出窗口的 chrome 扩展来注入网站并隐藏一些 div。
- 现在的问题是,我想用 url: https://app.example.de/dashboard/ 并用我的 contentscript.js 注入样式
- 另一个问题是:有时应用程序会重新加载页面。在此之后,所有注射都将丢失。是否有机会在不单击 popup.html 按钮的情况下始终注入 https://app.example.de/dashboard/?
如果页面已经打开,以下代码可以正常工作。
manifest.json
{
"name": "example stealth mode",
"version": "1.1",
"description": "lorem ipsum",
"browser_action": {
"default_icon": "icon-on.png",
"default_popup": "popup.html",
"default_title": "example stealth mode"
},
"manifest_version": 2,
"content_scripts": [
{
"matches": ["https://*.app.example.de/*"],
"js": ["jquery-1.11.0.min.js", "background.js"]
}
],
"background": {
"scripts": ["background.js"]
},
"permissions": [
"tabs", "https://*.app.example.de/*"
]
}
popup.js
document.addEventListener('DOMContentLoaded', function () {
document.getElementById('On').addEventListener('click', clickHandlerOn);
})
// An
function clickHandlerOn(e) {
chrome.extension.sendMessage({directive: "popup-click"}, function(response) {
this.close(); // close the popup when the background finishes processing request
});
}
background.js
chrome.extension.onMessage.addListener(
function(request, sender, sendResponse) {
switch (request.directive) {
case "popup-click":
// execute the content script
chrome.tabs.executeScript(null, { // defaults to the current tab
file: "contentscript.js", // script to inject into page and run in sandbox
allFrames: true // This injects script into iframes in the page and doesn't work before 4.0.266.0.
});
sendResponse({}); // sending back empty response to sender
break;
default:
// helps debug when request directive doesn't match
alert("Unmatched request of '" + request + "' from script to background.js from " + sender);
}
}
);
内容
$(document).ready(function() {
$('div#hlXXXContent').hide();
$('#hlYYY').hide();
$('#hlZZZ').hide();
$('h3.hlVVV').append(' Stealth Mode');
});
popup.html
<li><button class="hl123" id="On"><span class="hlSubmenuSelected">Stealthmode on</span</button></li>
