我已经尝试了很多方法(所有文档化的程序),在检查onUpdated.addListener上的URL时将脚本注入特定页面.最后,带有'executioncript'的下面代码似乎有效,但并不完美.我能够获取警报,但无法通过getElementById/getElementsByName查找页面的文档元素.
当我检查页面时,脚本被注入.但在错误控制台中,我得到:
拒绝加载chrome-extension://jfeiadiicafjpmaefageabnpamkapdhe/js/Leoscript.js.资源必须列在web_accessible_resources清单键中,以便由扩展名外的页面加载.
manifest.json的:
{
"name": "Leo Extension for Job Boards",
"version": "1.6",
"manifest_version": 2,
"content_security_policy": "script-src 'self'; object-src 'self'",
"description": "Leo Extension",
"background": {
"scripts": ["js/Leojshelper.js"],
"persistent": true
},
"content_scripts": [
{
"matches": ["<all_urls>"],
"js": ["js/eventPage.js"],
"run_at" : "document_start"
}
],
"icons":{"48":"images/bob48.png", "128":"images/bob128.png"}, //Define any icon sizes and the files that you want to use with them. 48/128 etc.
"browser_action": {
"default_icon": "images/bob.png", // What icon do you want to display on the chrome toolbar
"default_popup": "LeoExtwatch.html" // The page to popup when button clicked.
},
"permissions": [
"tabs", "<all_urls>" // "http://*/*","https://*/*" // Cross Site Access Requests
],
"web_accessible_resources": ["js/LeoScript.js"]
}
我还给了脚本"web_accessible_resources"权限,但仍然没有成功.后台脚本中的代码:
chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) {
if (changeInfo.status == 'complete') {
if (tab.url.indexOf("in.yahoo") !== -1) {
chrome.tabs.update(tabId, { url: "https://login.yahoo.com/config/mail?.intl=us" });
chrome.tabs.executeScript(tabId, {
code: "document.body.appendChild(document.createElement('script')).src='" +
chrome.extension.getURL("js/LeoScript.js") + "';"
}, null);
LeoScript.js中的代码,将被注入特定页面.
$(document).ready(function () {
alert('injected');
document.getElementById('username').value='aaaaaaa';
});
内容脚本:我用来注入脚本的eventPage.js.
var script = document.createElement('script');
script.src = chrome.extension.getURL("js/Leoscript.js");
(document.body || document.head || document.documentElement).appendChild(script);
如果上述代码中的任何更改将解决权限问题,请指出我.提前致谢.

更新:终于找到了你的问题.在eventPage.js中,您尝试注入未列入白名单的js/Leoscript.js,而不是js/LeoScript.js(使用大写"S"),该列表已列入白名单.请注意,URL 区分大小写!
chrome.tabs.executeScript(tabId, {file: 'js/LeoScript.js'});
LeoScript.js:
alert('injected');
document.getElementById('username').value='aaaaaaa';

编辑:
这是工作的版本,其中的组合web_accessible_resources和注射用
的manifest.json
{
"name":"Off Screen Tabs Demo",
"description":"This demonstrates Off Screen Tabs API",
"manifest_version":2,
"version":"1",
"permissions":["tabs","<all_urls>"],
"browser_action":{
"default_icon":"screen.png",
"default_popup":"popup.html"
},
"web_accessible_resources": ["js/LeoScript.js"] ,
"permissions":["tabs","<all_urls>"]
}
LeoScript.js
alert("Injected..");
popup.html
<html>
<head>
<script src="popup.js"></script>
</head>
<body>
</body>
</html>
popup.js*
document.addEventListener("DOMContentLoaded",function (){
chrome.tabs.executeScript( {"file": "js/LeoScript.js"});
});
如果你仍然有问题让它运行,请告诉我
