javascript - 我想在弹出框中启用javascript

Question

我的弹出窗口无法显示页面时出现错误，我想从页面的外部弹出窗口，我不希望页面与内部代码合并，所以我弹出窗口并包含我的外部页面，而无需更改外部代码。这是我以前的一些代码。

$(document).ready(function(){
    $('#content').load("google.com");
});

> here is my css style for my codestrong text

  .modalDialog {
  position: fixed;
  font-family: Arial, Helvetica, sans-serif;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: rgba(0,0,0,0.8);
  z-index: 99999;
  opacity:0;
  -webkit-transition: opacity 400ms ease-in;

请仅在控制台中阅读错误。
我收到以下错误：

js:1 Access to XMLHttpRequest at 'https://stacksnippets.net/google.com' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

这是因为禁用了通过AJAX从其他网站加载内容。
您可以尝试使用JSONP，如另一个问题中的此处所述：No response from MediaWiki API using jQuery
