模态窗口关闭时刷新父页面的组件

Question

I have a modal window, simulation JavaScript confirm box. Depending on button click ie, cancel button or ok button I want to refresh some component of the parent page. But unfortunately it is not working. As you can see from the code, I want to set values to the two textfields to "", hide a panel and set selected option of dropdown to zero. This is not happening, the components are remaining unrefreshed.

    public class ModalConfirmWindow extends WebPage {

    private ModalWindow modalConfirmWindow;
    private UserAssignmentInfoPanel userAssignmentInfoPanel;
    private DropDownChoice choice;
    private TextField scheduledTimeField;
    private DateTextField deadLineField;
    private int numberOfConflictingDays;

    public ModalConfirmWindow(ModalWindow modalConfirmWindow, UserAssignmentInfoPanel userAssignmentInfoPanel, DropDownChoice choice, TextField scheduledTimeField, DateTextField deadLineField, int numberOfConflictingDays) {
        this.modalConfirmWindow = modalConfirmWindow;
        this.userAssignmentInfoPanel = userAssignmentInfoPanel;
        this.choice = choice;
        this.scheduledTimeField = scheduledTimeField;
        this.deadLineField = deadLineField;
        this.numberOfConflictingDays = numberOfConflictingDays;
        add(new ModalConfirmWindowForm("form"));
    }

    private class ModalConfirmWindowForm extends Form {

        private static final long serialVersionUID = 10090L;

        public ModalConfirmWindowForm(String id) {
            super(id);

            add(new Label("value", " " + numberOfConflictingDays +" ").add(new SimpleAttributeModifier("style", "color: red")));
            add(new AjaxButton("cancelButton", this) {

                @Override
                protected void onSubmit(AjaxRequestTarget target, Form form) {
                                            // I am trying to refresh the component here
                    String javaScript = "document.getElementById('"+ userAssignmentInfoPanel.getMarkupId() +"').display = 'none';" +
                                        "document.getElementById('"+ choice.getMarkupId() +"').options[0].selected = 'selected';" +
                                        "document.getElementById('"+ scheduledTimeField.getMarkupId() +"').value = \"\";" +
                                        "document.getElementById('"+ deadLineField.getMarkupId() +"').value = \"\";";                                       
                    //target.appendJavascript(javaScript);
                    //scheduledTimeField.add(new SimpleAttributeModifier("value", ""));
                    //target.addComponent(scheduledTimeField);
                    //modalConfirmWindow.close(target);
                    modalConfirmWindow.close(target);
                    target.appendJavascript(javaScript);
                }
            });
            add(new AjaxButton("okButton", this) {

                @Override
                protected void onSubmit(AjaxRequestTarget target, Form form) {
                    modalConfirmWindow.close(target);
                }
            });
        }

    }
}

How can I do this?

I have solved the problem. I am giving the solution so that it may help future users. The modal window page is :

    public class ModalConfirmWindow extends WebPage {

    private Page parentPage;
    private ModalWindow modalConfirmWindow;    
    private int numberOfConflictingDays;

    public ModalConfirmWindow(Page parentPage, ModalWindow modalConfirmWindow, int numberOfConflictingDays) {
        this.parentPage = parentPage;
        this.modalConfirmWindow = modalConfirmWindow;        
        this.numberOfConflictingDays = numberOfConflictingDays;
        add(new ModalConfirmWindowForm("form"));
    }    

    private class ModalConfirmWindowForm extends Form {

        private static final long serialVersionUID = 10090L;

        public ModalConfirmWindowForm(String id) {
            super(id);

            add(new Label("value", " " + numberOfConflictingDays +" ").add(new SimpleAttributeModifier("style", "color: red")));
            add(new AjaxButton("cancelButton", this) {

                private static final long serialVersionUID = 10091L;

                @Override
                protected void onSubmit(AjaxRequestTarget target, Form form) {        
                    ((ParentPage)parentPage).setCancelButtonClicked(true);
                    modalConfirmWindow.close(target);
                }
            });
            add(new AjaxButton("okButton", this) {

                private static final long serialVersionUID = 10092L;

                @Override
                protected void onSubmit(AjaxRequestTarget target, Form form) {
                    ((ParentPage)parentPage).setCancelButtonClicked(false);
                    modalConfirmWindow.close(target);
                }
            });
        }

    }
}

Here the ParentPage is the page from which the modal window is generated. In the ParentPage I have a field isCancelButtonClicked and its getter and setter. In that page I have set

                modalConfirmWindow.setCloseButtonCallback(new ModalWindow.CloseButtonCallback() {

                    private static final long serialVersionUID = 10093L;

                    public boolean onCloseButtonClicked(AjaxRequestTarget target) {
                        ParentPage.this.isCancelButtonClicked = true;
                        return true;
                    }
                });
                modalConfirmWindow.setWindowClosedCallback(new ModalWindow.WindowClosedCallback() {

                    private static final long serialVersionUID = 10094L;

                    public void onClose(AjaxRequestTarget target) {
                        if (ParentPage.this.isCancelButtonClicked) {
                            String javascript = "document.getElementById('"+ scheduledTimeField.getMarkupId() +"').value = \"\";" +
                                                "document.getElementById('"+ deadLineField.getMarkupId() +"').value = \"\";" +
                                                "document.getElementById('"+ totalLabel.getMarkupId()+"').style.display = 'none';" +
                                                "document.getElementById('"+ choice.getMarkupId() +"').options[0].selected = 'selected';" +
                                                "document.getElementById('"+ choice.getMarkupId() +"').disabled = true;" +
                                                "document.getElementById('"+ userAssignmentInfoPanel.getMarkupId() +"').style.display = 'none';";
                            target.appendJavascript(javascript);
                        }                            
                    }
                });

And voilà. Thanks.

You'll probly have better luck if you use wicket models instead of javascript. Something like this: @Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
// I am trying to refresh the component here
userAssignmentInfoPanel.setVisible(false);
target.add(userAssignmentInfoPanel);
choice.getModelObject().setSelected(0);
target.add(choice);
scheduledTimeField.setModelObject("");
deadLineField.setModelObject("");
target.add(scheduledTimeField);
target.add(deadLineField);
} @Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
// I am trying to refresh the component here
userAssignmentInfoPanel.setVisible(false);
target.add(userAssignmentInfoPanel);
choice.getModelObject().setSelected(0);
target.add(choice);
scheduledTimeField.setModelObject("");
deadLineField.setModelObject("");
target.add(scheduledTimeField);
target.add(deadLineField);
}
