Ajax Chinese parameter garbled

The core of Ajax technology is JavaScript, and JavaScript uses UTF-8 encoding, so when the page uses GBK or other encoding, and there is no encoding conversion, there is a problem of Chinese garbled.

The following is a solution that uses the Get and post methods respectively, and the page uses GBK and UTF-8 to encode different test results and garbled characters in IE and ff.

Method of transmitting value	Client-side encoding	Server-side encoding	Ie	Ff	Solution Solutions
GET	UTF-8	UTF-8	Garbled when receiving parameters passed by $_get	Normal	Client Url=encodeuri (URL)
GET	GBK	GBK	Normal	Garbled when receiving parameters passed by $_get	Client Url=encodeuri (URL) server-side $str =iconv ("UTF-8", "GBK", $str)
POST	UTF-8	UTF-8	Garbled when receiving parameters passed by $_get	Normal	Client Url=encodeuri (URL)
POST	UTF-8	UTF-8	Normal when receiving parameters passed by $_post	Normal when receiving parameters passed by $_post	Recommended mode of Use
POST	GBK	GBK	Normal	Garbled when receiving parameters passed by $_get	Client Url=encodeuri (URL) server-side $str =iconv ("UTF-8", "GBK", $str)
POST	GBK	GBK	Garbled when receiving parameters passed by $_post	Garbled when receiving parameters passed by $_post	Server-side $str =iconv ("UTF-8", "GBK", $str)

Another problem may exist in IE: This operation could not be completed because of an error c00ce56e.

The header (' Content-type:text/html;charset=utf8 ') is changed to header (' Content-type:text/html;charset=utf-8 ') when the encoding is set.

Examples encountered in development:

Through the jquery $.get () method to pass Chinese parameters, background receive, page encoding is not set, Firefox normal, ie garbled

var name = "China"; var url = "/movies/getmoviename?name=" + Name;$.get (url,{}, function () {}, "JSON");

Workaround:

[1] JS Request two times encoding: Url=encodeuri (URL); Url=encodeuri (URL); i.e. Url=encodeuri (encodeURI (URL));

var name = encodeURI (encodeURI ("China")); var url = "/movies/getmoviename?name=" + Name;$.get (url,{}, function () {}, "JSON")

[2] Decoding

(1) C # Background decoding:

public void Getmoviename (string name) {    //httputility.urldecode method    name = System.Web.HttpUtility.UrlDecode ( name);    Server.urldecode method    name = Server.urldecode (name);  }

(2) JS decoding: decodeURI (URL);

Note: JS, C # encoding is decoded as follows:

Escape does not encode characters with 69: *,+,-,.,/,@,_,0-9,a-z,a-z

encodeURI does not encode 82 characters:!,#,$,&, ', (,), *,+,,,-,.,/,:,;,=,?,@,_,~,0-9,a-z,a-z

encodeURIComponent does not encode 71 characters:!, ', (,), *,-,.,_,~,0-9,a-z,a-z

[1], Js:escape (name):

JS can use escape when using data.

For example: Search the history record of the Tibetan.

Unicode values other than 0-255 are encoded with the output%u**** format, and in other cases the Escape,encodeuri,encodeuricomponent encoding results are the same.

(1) JS decoding: unescape (name);

(2) C#:httputility.urlencode () Httputility.urldecode ();

[2], Js:encodeuri ():

encodeURI () can be used as a whole when making a URL jump

For example: Location.href=encodeuri ("http://cang.baidu.com/do/s?word= Baidu &ct=21");

(1) JS decoding: decodeURI ();

(2) C # decoding: decodeURIComponent ();

[3], JS: encodeuricomponent ():

You need to use encodeURIComponent when passing parameters so that the combined URLs are not truncated by special characters such as #.

For example: <script language= "JavaScript" >document.write (' <a href= ' http://passport.baidu.com/?logout&aid=7 & u= ' +encodeuricomponent ("http://cang.baidu.com/bruce42") + ' "> Exit </a& gt; '); </script>

(1) decoding using decodeuricomponent (U);

(2) c#:[httpcontext.current.] Server.urldecode (URL) [HttpContext.Current.] Server.URLEncode (URL);
