问题 I am writing a text editor and need to provide a live word count. Right now I am using this extension method: public static int WordCount(this string s) { s = s.TrimEnd(); if (String.IsNullOrEmpty(s)) return 0; int count = 0; bool lastWasWordChar = false; foreach (char c in s) { if (Char.IsLetterOrDigit(c) || c == '_' || c == '\'' || c == '-') { lastWasWordChar = true; continue; } if (lastWasWordChar) { lastWasWordChar = false; count++; } } if (!lastWasWordChar) count--; return count + 1; } I

Is there an open source javascript rich text editor similar to gmail's? [closed]

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I've looked at free javascript html editors, and I haven't found any that I feel handle links intuitively. I like the way the gmail editor does it (also the same way blogger.com) does it. Does anyone know if there is an open source editor that handles linking that way? Jquery would be preferable. I use TinyMCE myself as Banzor suggests but here are a few other alternatives eash with their own strengths:

Temporaily disabling the C# Rich Edit undo buffer while performing syntax highlighting

由 我与影子孤独终老i 提交于 2019-12-06 09:48:19
问题 I already have a pretty decent syntax highlighter in my Rich Edit control but I have one final problem before it is fully useful: Whenever I run the syntax coloring it records those coloring actions in the undo buffer, which I do not really want. Is there any way to temporarily disable recording undo actions so that after a coloring the user can press undo and it will just undo the user's own actions and not the automated syntax highlighter? I don't think I have the time to implement the

Changing an extended RichTextBox text in constructor doesn't work

由 帅比萌擦擦* 提交于 2019-12-06 07:20:58
I have the following class: public partial class RichTextBoxEx : RichTextBox { public RichTextBoxEx() { InitializeComponent(); Text = "Some Text"; } } However, when I place it over a form and run the program, the RichTextBox is empty. What is the problem and how can I fix it? I assume there is something basic I'm missing here, but I cannot figure out what, and I did not manage to find any information about this. The property values which you set in constructor of the control are usually respected. But for Text property, the case is a bit different. I've already described about it in another

Submitting a form with a Dojo Rich Text Editor

由 北慕城南 提交于 2019-12-06 05:18:13
Does anyone out there know how to submit a form that contains a Dojo Rich Text Editor? I've tried adding the "name" attribute to my element that is decorated with dojoType="dijit.Editor", however, I don't see any of the HTML on my receiving process. I've checked the documentation and I don't see any clear example (other than connecting the on submit event of the form in question with another function that sets the data of a hidden input with the "value" of the Rich Text Editor"). I would assume there has to be some "easier" way to do this? Here im able to send the value to the server, and able
