javascript - iframe 的安全错误

Question

以下问题出现在Android 4.4及以上的设备上。

这是我们的 iframe 的样子:

<iframe frameborder=0 id="myIFRAME"></iframe>

以下是我们以编程方式获取 iframe 的方式:

if(document.getElementById("myIFRAME")){
        me.setMyIFRAME(document.getElementById("myIFRAME").contentWindow);
}

这会导致与协议(protocol)不匹配相关的安全错误:

"Uncaught SecurityError: Blocked a frame with origin "https://www.google.com" from accessing a frame with origin "file://". The frame requesting access has a protocol of "https", the frame being accessed has a protocol of "file". Protocols must match.

我们使用 Sencha touch 和 Cordova 来开发我们的项目。

Answer 1

Cordova security guide说:

If content is served in an iframe from a whitelisted domain, that domain will have access to the native Cordova bridge.

您是否尝试过添加外部域 to the whitelist里面 config.xml?

<access origin="https://google.com" />
