推荐答案

您好，

WebBrowser控件甚至您的代码都不会出现问题.您尝试加载的网页存在问题.该页面显然包含一个JavaScript错误，因此当发生此错误时，WebBrowser控件只是为您提供了停止运行该页面的选项.因此，您有两个选择:
1)忽略该错误并继续显示页面.这可能会导致页面的某些位不起作用，但这将意味着该页面显示出来.如果可以编辑页面，请执行此操作并解决错误:)
2)通过告诉用户并为用户提供选项或重定向其他页面来处理错误.

希望这会有所帮助，

Hi there,

This sin''t a problem with the WebBrowser control, or even your code. It is a problem with the web page you are trying to load. The page evidently contains a JavaScript error so when this error occurs the WebBrowser control is just giving you the option to stop running the page. You have two options therefore:
1) Ignore the error and continue to show the page. This may result in some bits of the page not working but it will mean that the page shows. If you can edit the page, do so and fix the error :)
2) Handle the error by telling the user and giving the user the option or redirecting a different page.

Hope this helps,
Ed
