我想在 ZK 中实现以在关闭其子窗口的同时刷新父窗口。
Parent.zul - 这有一个下拉列表和一个按钮(标记为添加到下拉列表)来为此下拉列表添加值。 单击此按钮时,它应该会打开一个子 winow,其中包含在下拉列表中输入文本的选项。
child.zul :这有一个文本框,用于输入下拉列表的值和一个"关闭"按钮。 单击"关闭"按钮时,它应关闭子窗口并刷新父窗口中的下拉列表。
提前感谢您的输入。

家长:袜子
<window id="sockWindow" title="New Sock" width="600px" apply="SockController" mode="modal" closable="true">
<div align="left" style="float: left;" >
<button id="btnLookup" label="Manage Lookup" width="150px"/>
</div>
</window>
袜子控制器.java:公共类 SockController 扩展 SelectorComposer {
@Listen("onClick = button#btnLookup")
public void onClickAdd() throws Exception {
showPopup(new EventListener<Event>() {
@Override
public void onEvent(final Event event) throws Exception {
Object someData = event.getData(); // cast to whatever object you expect to give.
//Make your refresh code here.
}
});
}
public static void showPopup(final EventListener<Event> eventListener)
throws InterruptedException {
//you can give more params with the method to add them as arguments.
Map arguments = new HashMap<String, String>();
arguments.put("source", "parent.zul");
// arguments.put("hid", hwid.toString());
// arguments.put("displaymode", displaymode);
openModal("/managelookup.zul",null, arguments, eventListener);
}
public static void openModal(final String page, final Component parent,
final Map<String, Object> obMap,
final EventListener<Event> onCloseListener)
throws InterruptedException {
for (final Map.Entry<String, Object> entry : obMap.entrySet()) {
Executions.getCurrent().setAttribute(entry.getKey(),
entry.getValue());
}
Executions.getCurrent().setAttribute(Composition.PARENT, null);
final Component createComponents = Executions.createComponents(page,

Component parent1 = createComponents;
parent1 = getWindow(parent1);
if (parent1 instanceof Window) {
final Window window = (Window) parent1;
if (onCloseListener != null) {
//attach the listener so when popup is closed the listener is called.
window.addEventListener(Events.ON_CLOSE, onCloseListener);
window.addEventListener(Events.ON_CANCEL, onCloseListener);
}
window.doModal();
}
}
}
子 : managelookup.zul:
<button id="cancel" label="Close"/>
</window>
ManageLookupsController.java:public ManageLookupsController() 抛出 Exception{
@Listen("onClick = button#cancel")
public void onClickCancel() {
manageLookup.setVisible(false);
manageLookup.detach();
Events.postEvent(Events.ON_CLOSE, windowOrSpaceOwner, someData);
}
}
我将在这里向您展示我们应用程序的一些示例:
在父作曲器中,我们打开弹出窗口并为回调提供一个事件侦听器:
public void onActionShowPopup () {
showPopup(new EventListener<Event>() {
@Override
public void onEvent(final Event event) throws Exception {
Object someData = event.getData(); // cast to whatever object you expect to give.
//Make your refresh code here.
}
});
}
public static void showPopup(final EventListener<Event> eventListener)
throws InterruptedException {
//you can give more params with the method to add them as arguments.
final Map<String, Object> args = new HashMap<>();
args.put("modus", "modal");
openModal("/WEB-INF/webpages/zk/popup/some_popup.zul",null, args, eventListener);
}
public static void openModal(final String page, final Component parent,
final Map<String, Object> obMap,
final EventListener<Event> onCloseListener)
throws InterruptedException {
for (final Map.Entry<String, Object> entry : obMap.entrySet()) {
Executions.getCurrent().setAttribute(entry.getKey(),
entry.getValue());
}
Executions.getCurrent().setAttribute(Composition.PARENT, null);
final Component createComponents = Executions.createComponents(page,
parent, obMap);
Component parent1 = createComponents;
parent1 = getWindow(parent1);
if (parent1 instanceof Window) {
final Window window = (Window) parent1;
if (onCloseListener != null) {
//attach the listener so when popup is closed the listener is called.
window.addEventListener(Events.ON_CLOSE, onCloseListener);
window.addEventListener(Events.ON_CANCEL, onCloseListener);
}
window.doModal();
}
}
public Component getWindow (Component comp) {
if (comp != null && !comp instanceof Window) {
return getWindow(comp.getParent());
}
return comp;
}
当然,当您关闭时,在您的弹出窗口中:
Events.postEvent(Events.ON_CLOSE, windowOrSpaceOwner, someData);
我用这段代码和它在哪里工作创建了一个小提琴。
也许你可以看到你在哪里犯了错误?
希望这会有所帮助。
我假设您的子窗口是另一个具有模态属性的窗口,因此: 如果您使用的是 MVVM,则可以使用 GlobalCommand 来"刷新"父窗口。
在父窗口视图中,模型放置一个刷新下拉列表的方法,并在其中放置@GlobalCommand标记:
@GlobalCommand
public void refreshDropDown(){
//Your code here
}
在子窗口中,如果您有关闭窗口的方法,则将调用添加到该 globalCommand:
public void closeWindow(){
//your code to close the window here
BindUtils.postGlobalCommand(null, null, "refreshDropDown", null);
}
或者直接在子窗口中 zul 中调用它:
<button label="Close window" onClick="@command('close') @global-command('refresh')" />
