Keypress에서 ModalWindow를 닫습니다

StackOverflow https://stackoverflow.com/questions/5042426

문제

사용자가 키를 누르면 ModalWindow를 닫을 수 있습니다.

취소 버튼의 클릭 이벤트를 호출하는 KeyPress에 대한 JavaScript 리스너가 있습니다. 

jQuery("#"+modalWindowInfo.closeButtonId).click();
.

이 작업을 수행하는 것이 올바른 방법입니까?

Chrome에서 작동하지만 FF에서 작동하지 않지만 내 구체적인 구현이 될 수 있습니다.

도움이 되었습니까?

해결책

The 'right' way to do it is to call the server, then close it with the response. You can do this with an ajax behavior:

ModalTestPage.java

public class ModalTestPage extends WebPage {
    public ModalTestPage(PageParameters parameters) {
        super(parameters);

        final ModalWindow modal = new ModalWindow("modal");
        modal.setContent(new Fragment(modal.getContentId(), "window", this));
        add(modal);

        add(new AjaxLink<Void>("link") {
            @Override
            public void onClick(AjaxRequestTarget target) {
                modal.show(target);
            }
        });

        add(new CloseOnESCBehavior(modal));
    }

    private static class CloseOnESCBehavior extends AbstractDefaultAjaxBehavior {
        private final ModalWindow modal;
        public CloseOnESCBehavior(ModalWindow modal) {
            this.modal = modal;
        }    
        @Override
        protected void respond(AjaxRequestTarget target) {
            modal.close(target);
        }    
        @Override
        public void renderHead(Component component, IHeaderResponse response) {
            response.renderJavaScriptReference("https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js");
            response.renderJavaScript("" +
                "$(document).ready(function() {\n" +
                "  $(document).bind('keyup', function(evt) {\n" +
                "    if (evt.keyCode == 27) {\n" +
                getCallbackScript() + "\n" +
                "        evt.preventDefault();\n" +
                "    }\n" +
                "  });\n" +
                "});", "closeModal");
        }
    }
}

ModalTestPage.html

<html xmlns:wicket="http://wicket.apache.org">
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>

  <a wicket:id="link">SHOW</a>
  <div wicket:id="modal"></div>

<wicket:fragment wicket:id="window">
  Press ESC to dismiss
</wicket:fragment>
</body>
</html>

다른 팁

The example above is good, very good, however there is one issue which may be crucial for some programming users (was for me).

For the actual close to happen there are 2 ajax requests happening - first one is issued with the CloseOnESCBehavior which calls window.close. MW.close() would render javascript which would first do call to server to ask its windowClosedCallback, and would only then close (hide contents of) the modal window.

I'd suggest instead doing something like this - in the code of ModalWindow ctor: 

    add(new AbstractBehavior() {
        @Override
        public void renderHead(IHeaderResponse response) {
            response.renderOnDomReadyJavascript(
                    " if($(document).data('wicketWindowCloseBound')) {return;} "
                            + " $(document).data('wicketWindowCloseBound', true); "
                            + " $(document).bind('keyup', function(evt) {\n"
                            + "    if (evt.keyCode == 27) {\n"
                            + getCloseJavacript()
                            + "\n"
                            + "        evt.preventDefault();\n"
                            + "        evt.stopPropagation();\n"
                            + "    }\n"
                            + "  });\n");

        }
    });

Also, you can use Wicket Jquery UI

HTML

<div wicket:id="dialog">[dialog]</div>

Java

MessageDialog dialog = new MessageDialog("dialog", "Warning", "Is it ok?",
                        DialogButtons.OK_CANCEL, DialogIcon.WARN)
    {
        protected void onClose(AjaxRequestTarget target, DialogButton button)
        {
            if(button != null && button.equals(LBL_OK))
            {
                //do something here

                //note1: #equals() compare either DialogButton or String (button text)
                //note2: predefined button text are:
                //LBL_OK, LBL_CANCEL, LBL_YES, LBL_NO, LBL_CLOSE, LBL_SUBMIT
            }
        }   
    }

    this.add(dialog); //TODO: open it, using dialog.open(target);

And the ESC key works fine. You should see this aproach at Wicket JQuery UI demo page
