我一定错过了一些简单的东西，但我被卡住了。我在gwt中创建了一个FormPanel，根据firebug发送请求。该链接有效，因为我从 firebug 复制了 requestlink 并在浏览器窗口中进行了本地尝试。是的，客户端和服务器主机是相同的 --> localhost。但答案并没有到达 gwt。甚至客户端浏览器都没有——萤火虫没有显示任何结果。
这是我的小表格：
Button form = new Button ("SendForm", new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
logger.log(Level.FINER, "Creating SubmitForm...");
TextBox cmd = new TextBox();
cmd.setName("cmd");
cmd.setText("GetMenuitemList");
Button sendbutton = new Button("Senden");
logger.log(Level.FINEST, "Creating grid...");
Grid grid = new Grid(1, 2);
grid.setWidget(0, 0, new Label("Command"));
grid.setWidget(0, 1, cmd);
VerticalPanel vPan = new VerticalPanel();
//vPan.add(grid);
vPan.add(sendbutton);
logger.log(Level.FINEST, "Creating FormPanel...");
final FormPanel formPan = new FormPanel();
formPan.setMethod(FormPanel.METHOD_POST);
formPan.setAction(RequestHelper.getLink("Menu.php"));
logger.log(Level.FINEST, "Binding Send button...");
logger.log(Level.FINEST, "Binding SubmitHandler...");
formPan.addSubmitHandler(new SubmitHandler() {
@Override
public void onSubmit(SubmitEvent event) {
OptionPane.showMessageDialog("Form submit", event.toDebugString(), MessageType.INFO, true);
}
});
logger.log(Level.FINEST, "Binding SubmitCompleteHandler...");
formPan.addSubmitCompleteHandler(new SubmitCompleteHandler() {
@Override
public void onSubmitComplete(SubmitCompleteEvent event) {
OptionPane.showMessageDialog("Form SubmitComplete", event.toDebugString(), MessageType.INFO, true);
}
});
logger.log(Level.FINEST, "Adding grid to formpan...");
formPan.add(grid);
formPan.add(vPan);
logger.log(Level.FINEST, "Creating DialogBox...");
final DialogBox box = OptionPane.createClosableBox("TestForm", true);
sendbutton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
formPan.submit();
box.hide();
}
});
box.add(formPan);
box.center();
}
});
预期的答案如下所示：
{"sessionid":"6dbqibo25e0bn46fldqh37psj5","data":[{"title":"Start","Controller":"Start","Action":"Index","tooltip":"Startseite, Begr\u00fc\u00dfung","prefetch":"1"},{"title":"Register","Controller":"Person","Action":"Index","tooltip":"Neue Benutzer registrieren","prefetch":"0"},{"title":"Daten","Controller":"Contact","Action":"Index","tooltip":"Die eigenen Daten bearbeiten","prefetch":"1"},{"title":"Teilnehmerlisten","Controller":"Lists","Action":"Index","tooltip":"Listen der registrierten Benutzer","prefetch":"0"},{"title":"Suche","Controller":"Search","Action":"Index","tooltip":"Namenssuche nach Benutzer mit Kontaktm\u00f6glichkeit","prefetch":"1"},{"title":"Kalender","Controller":"Calendar","Action":"Index","tooltip":"Termine","prefetch":"1"},{"title":"Newsletter","Controller":"Newsletter","Action":"Index","tooltip":"Verschicken von Newslettern","prefetch":"1"},{"title":"Wettk\u00e4mpfer","Controller":"Competitor","Action":"Index","tooltip":"Zugriff auf Wettk\u00e4mpfer","prefetch":"1"},{"title":"Upload","Controller":"Upload","Action":"Index","tooltip":"Bilder, Videos o.\u00e4. hochladen","prefetch":"0"},{"title":"Administration","Controller":"Admin","Action":"Index","tooltip":"Datenbankfunktionen und Benutzerrechte","prefetch":"1"}]}
那么，这里出了什么问题？
顺便说一句，我会将这种技术用于登录表单。我读到，以表格形式执行此操作比通过 RequestBuilder （已经有效）更好。文件上传将在稍后进行，因此表单问题无论如何都需要答案...
先感谢您。马库斯
编辑：好的，我也在 Chromium、Konqueror 和 Opera 上进行了测试——代码有效。这只是火狐。让它与Firefox一起使用的想法？我是 eclipse 和 gwt 的新手……也许是一些编译器选项？
