Web浏览器控件的行为不同于IE

[英]Webbrowser control behaving different than IE

原文 2012-11-13 15:54:13 3 2 c#/ javascript/ .net/ html/ browser

in my application I use the WebBrowser-Control to display a local HTML-file. 在我的应用程序中，我使用WebBrowser-Control来显示本地HTML文件。 The file includes jQuery and a custom js-File. 该文件包括jQuery和自定义js文件。

When I open the file with IE (locally), everything works just fine. 当我使用IE（本地）打开文件时，一切正常。 However, if I display the file with the WebBrowser control in my application, JQuery is not fully working (Some stuff does work, things like $.(...)addClass('abc') does not). 但是，如果我在应用程序中使用WebBrowser控件显示文件，则JQuery无法完全正常工作（某些功能确实可以工作，例如$.(...)addClass('abc')功能不能工作）。

Anyone have an idea why this might be the case? 有人知道为什么会这样吗？ I'm using Navigate() to navigate to the HTML-file and then use InvokeScript on the WebBrowser's document to call a javascript function that is using jQuery. 我正在使用Navigate()导航到HTML文件，然后在WebBrowser的文档上使用InvokeScript来调用使用jQuery的javascript函数。 I've also tried calling the function by navigating to a javascript: -URL which didn't work as well. 我也尝试通过导航到javascript: -URL来调用该函数，但效果不佳。

Thankful for any help 感谢您的帮助

This is a long shot, but I have seen instances where the WebBrowser control defaults to an older version of the IE rendering engine for some reason even though a newer version of IE is installed. 这是一个很长的路要走，但是我看到一些实例，其中由于某些原因，即使安装了新版本的IE，WebBrowser控件仍默认使用旧版本的IE呈现引擎。 Some older versions of IE could have issues with jquery. 某些旧版本的IE可能与jquery有关。

Try adding some js to ensure it's using the version of IE you are expecting. 尝试添加一些js以确保它使用的是您期望的IE版本。

You have to set two registry keys, one for 32 bit and one for 64 bit applications. 您必须设置两个注册表项，一个用于32位，一个用于64位应用程序。

32 bit: 32位：

HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Internet Explorer\\MAIN\\FeatureControl\\FEATURE_BROWSER_EMULATION HKEY_LOCAL_MACHINE \\ SOFTWARE \\ Microsoft \\ Internet Explorer \\ MAIN \\ FeatureControl \\ FEATURE_BROWSER_EMULATION

Value Key: yourapplication.exe 值键：yourapplication.exe

64 bit: 64位：

HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Microsoft\\Internet Explorer\\MAIN\\FeatureControl\\FEATURE_BROWSER_EMULATION HKEY_LOCAL_MACHINE \\ SOFTWARE \\ Wow6432Node \\ Microsoft \\ Internet Explorer \\ MAIN \\ FeatureControl \\ FEATURE_BROWSER_EMULATION

Value Key: yourapplication.exe 值键：yourapplication.exe

The value to set this key to is ( taken from MSDN here ) as decimal values: 将此键设置为的值（从MSDN此处获取）为十进制值：

9999 (0x270F) Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive. 9999（0x270F）Internet Explorer9。无论！DOCTYPE指令如何，网页均以IE9标准模式显示。

9000 (0x2328) Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. 9000（0x2328）Internet Explorer9。包含基于标准的！DOCTYPE指令的网页以IE9模式显示。

8888 (0x22B8) Webpages are displayed in IE8 Standards mode, regardless of the !DOCTYPE directive. 8888（0x22B8）网页以IE8标准模式显示，无论！DOCTYPE指令如何。

8000 (0x1F40) Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. 包含基于标准！DOCTYPE指令的8000（0x1F40）网页以IE8模式显示。

7000 (0x1B58) Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. 包含基于标准的！DOCTYPE指令的7000（0x1B58）网页以IE7标准模式显示。
