在服务器端解码html

Question

I have a string which I want to encode on client side using JavaScript:

/* JS code */
var blogBody = $(".editor").val();
var blogBodyEnc = encodeURIComponent(blogBody)
// blogBody = "<p>text</p><p><br></p><p><br></p><p>text</p>";
// blogBodyEnc = "%3Cp%3Etext%3C%2Fp%3E%3Cp%3E%3Cbr%3E%3C%2Fp%3E%3Cp%3E%3Cbr%3E%3C%2Fp%3E%3Cp%3Etext%3C%2Fp%3E"

Then I'm passing encoded string blogBodyEnc to server using jquery ajax. And now I want to decode this string on server. I'm trying:

/* ASP.NET code */
string msg = HttpUtility.HtmlDecode(blogBodyEnc);
// blogBodyEnc = "%3Cp%3Etext%3C%2Fp%3E%3Cp%3E%3Cbr%3E%3C%2Fp%3E%3Cp%3E%3Cbr%3E%3C%2Fp%3E%3Cp%3Etext%3C%2Fp%3E"
// msg =         "%3Cp%3Etext%3C%2Fp%3E%3Cp%3E%3Cbr%3E%3C%2Fp%3E%3Cp%3E%3Cbr%3E%3C%2Fp%3E%3Cp%3Etext%3C%2Fp%3E"

Could anybody say what is wrong? I expecting to see html code after decoding on server side... but it still encoded.

Answer 1

您需要UrlDecode ，而不是HtmlDecode 。

Answer 2

I think he really wants:

function htmlEncode(value){
   return $('<div/>').text(value).html();
}

And call it as so:

var blogBodyEnc = htmlEncode($(".editor").val());

To then use

string msg = HttpUtility.HtmlDecode(blogBodyEnc);
