使用CEFSHARP逃脱JavaScript和HTML字符串
上下文：
我想使用嵌入Tinymce JS的CEFSHARPBROWSER加载HTML代码。
正确执行此操作的方法是：
Dim browser As ChromiumWebBrowser
Dim strHTMLPageCode As String = "<p>Hello</p>"
browser.GetMainFrame.ExecuteJavaScriptAsync("tinymce.activeEditor.setContent('" & strHTMLPageCode & "');"))
问题：
当strhtmlpagecode获得“真实” html（带有line feed，tag等）时，它不起作用，例如
<html>
<head>
<title>Href Attribute Example</title>
</head>
<body>
<h1>Href Attribute Example</h1>
<p>
<a href="https://www.freecodecamp.org/contribute/">The freeCodeCamp Contribution Page</a> shows you how and where you can contribute to freeCodeCamp's community and growth.
</p>
</body>
</html>
，我必须逃脱字符串。
我尝试过
browser.GetMainFrame.ExecuteJavaScriptAsync("tinymce.activeEditor.setContent('" & HttpUtility.HtmlEncode(strHTMLPageCode) & "');"))
browser.GetMainFrame.ExecuteJavaScriptAsync(HttpUtility.Javascriptencode("tinymce.activeEditor.setContent('" & HttpUtility.HtmlEncode(strHTMLPageCode) & "');")))
browser.GetMainFrame.ExecuteJavaScriptAsync(HttpUtility.JavaScriptStringEncode("tinymce.activeEditor.setContent('") & HttpUtility.HtmlEncode(strHTMLPageCode) & "');")
这些都没有用。
Context:
I want to load HTML code using a CEFSharpBrowser embedding a TinyMce JS.
The correct way to do it is:
Dim browser As ChromiumWebBrowser
Dim strHTMLPageCode As String = "<p>Hello</p>"
browser.GetMainFrame.ExecuteJavaScriptAsync("tinymce.activeEditor.setContent('" & strHTMLPageCode & "');"))
Issue:
It doesn't work when strHTMLPageCode got "real" html (with line feed, tags, etc) e.g.
<html>
<head>
<title>Href Attribute Example</title>
</head>
<body>
<h1>Href Attribute Example</h1>
<p>
<a href="https://www.freecodecamp.org/contribute/">The freeCodeCamp Contribution Page</a> shows you how and where you can contribute to freeCodeCamp's community and growth.
</p>
</body>
</html>
So, i had to escape the string.
I tried
browser.GetMainFrame.ExecuteJavaScriptAsync("tinymce.activeEditor.setContent('" & HttpUtility.HtmlEncode(strHTMLPageCode) & "');"))
browser.GetMainFrame.ExecuteJavaScriptAsync(HttpUtility.Javascriptencode("tinymce.activeEditor.setContent('" & HttpUtility.HtmlEncode(strHTMLPageCode) & "');")))
browser.GetMainFrame.ExecuteJavaScriptAsync(HttpUtility.JavaScriptStringEncode("tinymce.activeEditor.setContent('") & HttpUtility.HtmlEncode(strHTMLPageCode) & "');")
None of these worked.

问题在于HTML字符串，该字符串具有“非规则”线供稿。
我能够看到此问题，这要归功于开发器控制台，这要感谢：
browser.showdevtoolsdocked（me）The issue was in the html string which had "non regular" line feed.
I was able to see this issue thanks to the developper console, displayable thanks to :
