Wie kann ich diesen Code erstellen, um eine UTF-8 Formular-Textfläche mit jQuery / Ajax-Arbeit einzureichen?

Ich habe Probleme beim Formulare Absenden, die enthalten UTF-8-Zeichenfolgen mit Ajax. Ich entwickle eine Federbeine web-Anwendung läuft in einem Tomcat server. Dies ist die Umgebung, die ich zur Arbeit mit UTF-8:

Habe ich die Attribute URIEncoding="UTF-8" useBodyEncodingForURI="true" in die Connector tag zu Tomcat conf/server.xml Datei.
Ich habe eine utf-8_general_ci Datenbank

Ich bin mit dem nächsten filter, um sicherzustellen, dass meine Anfrage und die Antworten werden codiert in UTF-8

package filters;

import java.io.IOException;
import javax.servlet.*;

public class UTF8Filter implements Filter {
    public void destroy() {}

    public void doFilter(ServletRequest request,ServletResponse response, FilterChain chain)
        throws IOException, ServletException {
        request.setCharacterEncoding("UTF-8");
        response.setContentType("text/html;charset=UTF-8");
        chain.doFilter(request, response);
    }

    public void init(FilterConfig filterConfig) throws ServletException {
    }
}

Ich diesen filter nutzen WEB-INF/web.xml

Ich bin mit dem nächsten code für mein JSON-Antworten:

public static void populateWithJSON(HttpServletResponse response,JSONObject json)
{
   String CONTENT_TYPE="text/x-json;charset=UTF-8";
   response.setContentType(CONTENT_TYPE);
   response.setHeader("Cache-Control", "no-cache");
   try {
        response.getWriter().write(json.toString());
   } catch (IOException e) {
    throw new ApplicationException("Application Exception raised in RetrievedStories", e);
   }
}

Alles scheint gut zu funktionieren (die Inhalte kommen aus der Datenbank richtig angezeigt wird, und ich bin in der Lage, das senden von Formularen, die gespeichert werden in UTF-8 in der Datenbank). Das problem ist, dass ich bin nicht in der Lage, das senden von Formularen mit Ajax. Ich jQuery verwenden, und ich dachte, das problem war der Mangel an contentType-Feld in der Ajax-Anfrage. Aber ich lag falsch. Ich habe eine sehr einfache form, um Kommentare abzugeben, die beinhaltet eine id und einen Körper. Im Feld Text kann in verschiedenen Sprachen wie Spanisch, Deutsch oder was auch immer.

Wenn ich meine form mit dem Körper textarea mit contraseñaFirebug zeigt mir:

Request-Header

Host localhost:8080

Accept-Charset ISO-8859-1, utf-8;q=0.7;*q=0.7

Content-Type application/x-www-form-urlencoded; charset UTF-8

Wenn ich ausführen Speicherort Kopieren mit Parameter in Firebug, die Codierung scheint schon falsch:

http://localhost:8080/Cerepedia/corporate/postStoryComment.do?&body=contrase%C3%B1a&id=88

Dies ist mein jQuery-code:

function addComment() {
    var comment_body = $("#postCommentForm textarea").val();
    var item_id = $("#postCommentForm input:hidden").val();
    var url = rooturl+"corporate/postStoryComment.do?";
    $.post(url, { id:  item_id, body: comment_body } ,
        function(data){
        /* Do stuff with the answer */
    }, "json");  }

Einer Vorlage ein Formular mit jQuery verursacht der nächste Fehler auf server-Seite (Hinweis: ich bin mit Ruhezustand).

haben Sie versucht, indem Sie die folgende, bevor der Anruf :
```
$.ajaxSetup({ 
    scriptCharset: "utf-8" , 
    contentType: "application/json; charset=utf-8"
});
```
Die Optionen erklärt,hier.

contentType : Beim senden von Daten an den server, verwenden Sie diesen content-Typ. Default ist "application/x-www-form-urlencoded", und das ist gut für die meisten Fälle.

scriptCharset : Nur für Anfragen mit 'jsonp' oder 'Skript', dataType und BEKOMMEN geben. Kräfte der Anfrage interpretiert werden, einen bestimmten Zeichensatz. Nur für charset Unterschiede zwischen der remote-und lokale Inhalte.

Ich bin mit dem gleichen problem. Ich sah, Internet Explorer 8 sendet diesen header:
```
content-type = application/x-www-form-urlencoded
```
während Firefox sendet diese:
```
content-type = application/x-www-form-urlencoded; charset=UTF-8
```
Meine Lösung war einfach zwingen in jQuery zu verwenden, der Firefox content-type:
```
$.ajaxSetup({ scriptCharset: "utf-8" ,contentType: "application/x-www-form-urlencoded; charset=UTF-8" });
```

Ich hatte das gleiche problem und es behoben, durch Downgrade auf mysql-connector-odbc-3.51.16.

InformationsquelleAutor der Antwort Anders B

Ich hatte das gleiche problem auch und habe es behoben in dieser Weise:

In PHP, vor dem speichern der Daten in der Datenbank, habe ich die htmlentities() Funktion. Und während zeigt die Daten, die ich verwendet, die html_entity_decode() Funktion. Dieser arbeitete. Ich hoffe sehr das wird auch für Sie arbeiten.

Als die Ausnahme ist ein jdbc-Fehler, Ihre beste Ansatz ist, um zu erfassen die Eingabe, bevor Sie an die Datenbank gesendet wird.

java.sql.BatchUpdateException: Incorrect string value: '\xF1a' für die Spalte 'Körper' in Zeile 1

Einem einzigen Charakter die Ursache der Ausnahme.

Kann es der Fall sein, die Sie überschreiben müssen einige Zeichen manuell. Finden Sie, beim arbeiten mit nicht-Latein-alphabet-Sprachen (wie ich), dass dies eine gemeinsame Schmerz.

InformationsquelleAutor der Antwort Theofanis Pantelides

Ich sehe das problem viel.
Die meta-funktioniert nicht immer in Ihrem PHP-Operationen mit den Daten, so geben Sie Folgendes am Anfang:
```
<?php header('Content-type: text/html; charset=utf-8');  ?>
```
