这里有没有人有/可以开发可以共享其知识的IE扩展的经验?这将包括代码示例,或指向好的示例的链接,或有关过程的文档,或任何内容。
我真的很想这样做,但是我遇到了糟糕的文档,糟糕的代码/示例代码/缺少它。您可以提供的任何帮助/资源将不胜感激。
具体来说,我想先介绍如何从IE扩展中访问/操作DOM。
编辑,更多详细信息:
理想情况下,我想植入一个工具栏按钮,单击该工具栏按钮时,会弹出一个包含指向外部站点的链接的菜单。我还想访问DOM并根据某些条件在页面上植入JavaScript。
在IE扩展中保留信息的最佳方法是什么?在Firefox / Chrome /最现代的浏览器中,您可以使用window.localStorage,但显然对于IE8 / IE7,这不是一种选择。也许是SQLite数据库或类似的?可以假设将.NET 4.0安装在用户的计算机上吗?
window.localStorage
我不想使用Spice IE,因为我也想构建一个与IE9兼容的。我也向这个问题添加了C 标记,因为如果最好在C 中构建一个,则可以这样做。
[更新]我正在更新此答案,以在带有 Visual Studio 2017社区的* Windows 10 x64中 使用 Internet Explorer 11 。此答案的先前版本(对于Internet Explorer 8,在Windows 7 x64和Visual Studio 2010中)在此答案的底部。 ***
我使用 的Visual Studio 2017年的社区 , C# , .Net框架4.6.1 ,所以某些步骤可能是你稍有不同。
您需要以 管理员 身份 打开Visual Studio 来构建解决方案,以便构建后脚本可以注册BHO(需要注册表访问)。
首先创建一个类库。我叫我 InternetExplorerExtension 。
将这些引用添加到项目中:
"Microsoft Internet Controls"
"Microsoft.mshtml"
注意: 尽管可以在“添加引用”窗口中找到MSHTML,但仍未在我的系统中注册它。这在构建时导致错误:
找不到类型库“ MSHTML”的包装程序集
可在http://techninotes.blogspot.com/2016/08/fixing-cannot-find-wrapper- assembly-for.html上找到此修复程序, 或者,您可以运行以下批处理脚本:
"%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Community\Common7\Tools\VsDevCmd.bat" cd "%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Community\Common7\IDE\PublicAssemblies" regasm Microsoft.mshtml.dll gacutil /i Microsoft.mshtml.dll
创建以下文件:

最后是表格,我们将使用它来配置选项。在此表格中,放置a TextBox和Ok Button。将按钮的 DialogResult 设置为 Ok 。将此代码放在表单代码中:
TextBox
Button
using System.Windows.Forms; namespace InternetExplorerExtension { public partial class HighlighterOptionsForm : Form { public HighlighterOptionsForm() { InitializeComponent(); } public string InputText { get { return this.textBox1.Text; } set { this.textBox1.Text = value; } } } }
在项目属性中,执行以下操作:
C:\Program Files (x86)\Internet Explorer\iexplore.exe
http://msdn.microsoft.com/en-us/library/ms976373.aspx#bho_getintouch
在“构建事件”选项卡中,将 “构建后事件”命令行设置 为:
“%ProgramFiles(x86)%\ Microsoft SDKs \ Windows \ v10.0A \ bin \ NETFX 4.6.1 Tools \ gacutil.exe” / f / i“ $(TargetDir)$(TargetFileName)”
“%windir%\ Microsoft.NET \ Framework \ v4.0.30319 \ RegAsm.exe” /取消注册“ $(TargetDir)$(TargetFileName)”
“%windir%\ Microsoft.NET \ Framework \ v4.0.30319 \ RegAsm.exe”“ $(TargetDir)$(TargetFileName)”
注意: 即使我的计算机是x64,我也使用了非x64的路径gacutil.exe并且可以正常工作… x64的专用路径是:
gacutil.exe
C:\ Program Files(x86)\ Microsoft SDKs \ Windows \ v10.0A \ bin \ NETFX 4.6.1 Tools \ **x64 \** gacutil.exe
64位IE 需要64位编译和64位注册的BHO。尽管我只能使用32位IE11进行调试,但是32位注册扩展也可以通过运行64位IE11来工作。
这个答案似乎对此有一些附加信息:https : //stackoverflow.com/a/23004613/195417
如果需要,可以使用64位重装:
%windir%\ Microsoft.NET \ Framework **64 \** v4.0.30319 \ RegAsm.exe
此加载项如何工作
我没有更改加载项的行为。。。下面介绍一下IE8部分。
伙计…这是很多工作!我很好奇如何做到这一点,以至于我自己做了。
首先…信誉不全是我的。这是我在以下网站上发现的内容的汇总:
当然,我希望我的答案具有您要求的功能:
我将逐步介绍它,以及如何在 Windows 7 x64中* 使用 Internet Explorer 8 进行 管理 …请注意,我无法在其他配置中进行测试。希望你理解=) *
我使用的是 Visual Studio 2010 , C#4 , .Net Framework 4 ,因此其中一些步骤可能对您略有不同。
创建了一个类库。我叫我 InternetExplorerExtension 。
注意:这些参考可能在每台计算机的不同位置。
这是我在csproj中的参考部分包含的内容:
<Reference Include="Interop.SHDocVw, Version=1.1.0.0, Culture=neutral, PublicKeyToken=90ba9c70f846762e, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <EmbedInteropTypes>True</EmbedInteropTypes> <HintPath>C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\PrivateAssemblies\Interop.SHDocVw.dll</HintPath> </Reference> <Reference Include="Microsoft.CSharp" /> <Reference Include="Microsoft.mshtml, Version=7.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"> <EmbedInteropTypes>True</EmbedInteropTypes> </Reference> <Reference Include="System" /> <Reference Include="System.Data" /> <Reference Include="System.Drawing" /> <Reference Include="System.Windows.Forms" /> <Reference Include="System.Xml" />
创建文件的方式与更新IE11文件的方式相同。
您可以取消注释IE11版本中的以下几行:
... // @Eric Stob: Thanks for this hint! // This was used to prevent this method being executed more than once in IE8... but now it seems to not work anymore. if (pDisp != this.site) return; ...
与IE11版本相同。
最后是表格,我们将使用它来配置选项。在此表格中,放置a TextBox和Ok Button。将按钮的 DialogResult 设置为 Ok 。该代码与IE11插件相同。
“ C:\ Program Files(x86)\ Microsoft SDKs \ Windows \ v7.0A \ Bin \ NETFX 4.0 Tools \ **x64** \ gacutil.exe” / f / i“ $(TargetDir)$(TargetFileName)”
“ C:\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ RegAsm.exe” /取消注册“ $(TargetDir)$(TargetFileName)”
“ C:\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ RegAsm.exe”“ $(TargetDir)$(TargetFileName)”
注意: 由于我的计算机是x64,因此我的计算机上gacutil可执行文件的路径中有一个特定的x64,可能与您的不同。
64位IE 需要64位编译和64位注册的BHO。使用64位RegAsm.exe(通常位于C:\ Windows \ Microsoft.NET \ Framework64 \ v4.0.30319 \ RegAsm.exe中)
它遍历所有DOM树,用黄色背景本身替换使用按钮配置的文本。如果单击发黄的文本,它将调用动态插入页面的javascript函数。默认单词是“浏览器”,因此它与很多单词匹配! 编辑: 更改要突出显示的字符串后,您必须单击URL框,然后按Enter键。F5将不起作用,我认为这是因为F5被视为“导航”,并且需要收听导航事件(也许)。我稍后将尝试解决。
现在,该走了。我很累。随便问问题…也许是因为我要去旅行而无法回答…三天后我会回来,但在此期间我会尽量来这里。
