错误：拒绝访问属性“x”

当尝试访问您没有权限的对象时，会出现JavaScript异常“拒绝访问属性”。

消息

DOMException: Blocked a frame with origin "x" from accessing a cross-origin frame. (Chromium-based)
DOMException: Permission denied to access property "x" on cross-origin object (Firefox)
SecurityError: Blocked a frame with origin "x" from accessing a cross-origin frame. Protocols, domains, and ports must match. (Safari)

错误类型

DOMException.

哪里出错了？

尝试访问您没有权限的对象。这可能是从不同域加载的<iframe>元素，您违反了同源策略。

示例

没有访问文档的权限

html

<!doctype html>
<html lang="en-US">
  <head>
    <iframe
      id="myframe"
      src="http://www1.w3c-test.org/common/blank.html"></iframe>
    <script>
      onload = function () {
        console.log(frames[0].document);
        // Error: Permission denied to access property "document"
      };
    </script>
  </head>
  <body></body>
</html>
