Problem with "HttpUtility.HtmlEncode()"

msman88 · #1 (**permalink**) March 5th, 2010, 01:47 PM

Code [1]

Code:

Response.Clear();
Response.Write(@"document.write(""<html><body>case 1) Worked well</body></html>"");");
Response.End();

The above code prints
Code [2]

Code:

document.write(<html><body>case 1) worked well</body></html>");

and then it's called by a javascript as external javascript file, as below
Code [3]

Code:

<script type="text/javascript" src="http://localhost:52027/Work+notWork/Default.aspx"></script>

===================
But when I change the Code [1] to the following, it does not work.

Code:

Response.Clear();
Response.Write(HttpUtility.HtmlEncode(@"document.write(""<html><body>case 2) worked well</body></html>"");"));
Response.End();

The difference above is using the "HttpUtility.HtmlEncode", but I must use it, so what should I do to discover problem?
For more details, run the following and touch waht I mean

Why did you think that "I must use it"? Note: what you are trying to encode is javascript, and after encoded, it's not valid javascript any more.

I don't understand your problem. If case 1 works, then use it. Why do you HAVE to use HtmlEncode?

Basically encoding the document.write line as HTML entities means its not valid javascript any more.

You're not trying to do this are you?

Code:

Response.Write("document.write(\"" + HttpUtility.HtmlEncode(@"document.write(""<html><body>case 2) worked well</body></html>"");") + "\");");

You HtmlEncode the stuffs that will otherwise confuse the "receiving end", but javascript is entirely valid "as is" when included as part of HTML.

On a separate page, it is not a good practice to include javascript as part of html.

Mr.you are near of idea.
I can clarify more...
What I actually I want to get is same as the following:
http://ads.adbrite.com/mb/text_group...s=3732385f3930

It contains <html> codes, and it's valid javascript.

Mr. Imar, if you are unable, please keep silent.

I think you misunderstood some of the replies above. Let's stay focused on the problem, and remember people are helping out of their kindness. Couple of things:
1) Yes, the link you give is a javascript containing code that generates html document or at least portion of it. The content of that javascript is served up by some PHP code;
2) If you want the same thing, the simplest way is to have the content (assume static) in a file and simply serve it as is;
3) You tried to generate that javascript from a piece of C# code, is that really necessary? If not, do what's mentioned in above point 2. Don't make things more difficult than needed.
4) If it's truly necessarily to generate from C#, read some of the above replies again, and try to understand what people said. All they said was: don't html encode your javascript portion, and the HtmlEncode() call away.

That's exactly my point. If people don't respond, they're probably busy. Posting "bump" messages clutters up the forum and people's mail boxes and generally decreases your chances of someone replying....
