从浏览器应用程序中从Silverlight执行javascript
[英]Executing javascript from Silverlight out of browser app
问题描述
I have a silverlight app that uses JavaScript to process images from facebook. 
我有一个Silverlight应用程序，该应用程序使用JavaScript处理来自Facebook的图像。 The JavaScript calls context.drawImage which throws a security exception (NS_ERROR_DOM_SECURITY_ERR) which I understood happens since the image is not hosted by my server, but from a different server (in this case facebook). JavaScript调用context.drawImage会引发安全异常（NS_ERROR_DOM_SECURITY_ERR），由于该图像不是由我的服务器托管，而是由其他服务器（在本例中为facebook）托管，因此我理解这种情况会发生。
After some research, I found that the correct permissions would be given to the app if run out of browser, but now I understood that I can't run the JavaScript since there is no browser to host it. 经过一番研究，我发现如果在浏览器中运行完该应用程序后，该应用程序将获得正确的权限，但是现在我知道我无法运行该JavaScript，因为没有浏览器可以托管它。
Is this correct? 这个对吗？ If so, can anyone suggest a workaround for running the JavaScript with the needed permissions to access a image hosted by a different server. 如果是这样，任何人都可以提出一种解决方法，以具有访问其他服务器托管的图像所需的权限来运行JavaScript。
Thanks! 谢谢！

You are correct. 你是对的。 JavaScript cannot run because there's no browser to host it. JavaScript无法运行，因为没有浏览器来托管它。
The only solution is to rewrite the JavaScript. 唯一的解决方案是重写JavaScript。
