[英]Chrome Extension: Interacting with iframe embedded within popup
I am writing a Chrome extension that needs to interact with urls that the user does not have open.我正在编写一个 Chrome 扩展程序,它需要与用户没有打开的 url 进行交互。 Therefore I am using hidden iframes that are embedded within the popup, and am attempting to click a button within the iframe.
因此,我使用嵌入在弹出窗口中的隐藏 iframe,并尝试单击 iframe 中的按钮。 However, I am receiving a same origin policy error.
但是,我收到了同源策略错误。 I know that it is possible for an extension to interact with iframes of a different domain via content scripts when the iframe is on the tab that the user has open, but I am not sure if it is possible to use content scripts to interact with iframes directly in the popup.
我知道当 iframe 位于用户打开的选项卡上时,扩展程序可以通过内容脚本与不同域的 iframe 交互,但我不确定是否可以使用内容脚本与 iframe 交互直接在弹出窗口中。
Here is my code:这是我的代码:
manifest.json清单文件
"content_scripts": [
{
"js": [ "bin/jquery.min.js", "interaction.js" ],
"all_frames": true,
"run_at": "document_start",
"matches": [ "http://*/*",
"https://*/*" ]
}],
"permissions": [
"activeTab",
"tabs",
"http://*/",
"https://*/"
],
interaction.js交互.js
$(document).ready(function() {
$('div#iframes').append("<iframe id='shop' src='https://www.google.com/'></iframe>")
$('iframe').bind("load", function() {
$('iframe').contents().find("html").ready(function() {
loadedStores += 1;
if (loadedStores == carts.totalStores) {
$('div#cost').append(carts.grandTotal)
showMain();
}
})
})
})
Error错误
Uncaught SecurityError: Blocked a frame with origin "chrome-extension://mapgjiofchdchalgcifmdolgcekfaadp" from accessing a frame with origin "https://www.google.com/". The frame requesting access has a protocol of "chrome-extension", the frame being accessed has a protocol of "http". Protocols must match.
The error occurs in interaction.js in the third line (with the load callback).错误发生在第三行(带有加载回调)的interaction.js 中。 Does anyone know any changes I should make to the content script to allow me to interact with the iframe?
有谁知道我应该对内容脚本进行任何更改以允许我与 iframe 交互? Or if there are other approaches I should take?
或者如果我应该采取其他方法? Thanks!
谢谢!
Your frame will also have a content script injected.您的框架还将注入一个内容脚本。
You need to communicate with that content script using Messaging and make it do what you need.您需要使用 Messaging 与该内容脚本进行通信并使其执行您需要的操作。
