我需要在 Wicket 模式窗口的标题栏中添加一个按钮。我在 Wicket API 中找不到任何有用的东西来帮助我。有没有办法以这种方式自定义标题栏?

你可以在 CSS 的帮助下实现这种效果。创建您的自定义模式窗口(以防您不想创建自定义样式)并指定 css 资源。
package org.ru5.test;
import org.apache.wicket.ResourceReference;
import org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow;
import org.apache.wicket.markup.html.CSSPackageResource;
import org.apache.wicket.markup.html.resources.CompressedResourceReference;
import org.apache.wicket.model.IModel;
public class CustomModalWindow extends ModalWindow {
private static final long serialVersionUID = 1L;
private static ResourceReference CSS = new CompressedResourceReference(
CustomModalWindow.class, "res/custom-modal.css");
/**
* Creates a new modal window component.
*
* @param id
* Id of component
*/
public CustomModalWindow(final String id) {
super(id);
init();
}
/**
* Creates a new modal window component.
*
* @param id
* Id of component
* @param model
* Model
*/
public CustomModalWindow(final String id, final IModel<?> model) {
super(id, model);
init();
}
private void init() {
add(CSSPackageResource.getHeaderContribution(CSS));
}
}
/org/ru5/test/CustomModalWindow.html

</html>
您需要的一切:
/org/ru5/test/res/custom-modal.css
.headBtn{position: absolute; z-index: 20001; top: 2px; left: 200px;}
/org/ru5/test/TestPanelForTestWindow.html
....
<div class="headBtn">
<input type="button" value="ok">
</div>
....
您可以尝试覆盖 modal.js 函数,或者在 JS DOM 的帮助下制作一个技巧。希望这会有所帮助。
根据 /org/apache/wicket/extension/ajax/markup/html/modal/res/modal.js 您不能通过 wicket api 修改模态窗口装饰器,因为模态窗口标记完全在 javascript 中定义。因此,与往常一样,您可以选择简单但不好的方式并自行替换 modal.js,或者您几乎无法真正更改显示后的模态窗口,使用 js 修改类“w_captionText”的跨度。或者可能是(我没有测试它)您可以在 Caption 属性中定义您自定义的代码,并告诉检票口不要在此 Caption 中转义特殊的 html 字符。可能会有所帮助。
有点破解,但有效:
import org.apache.wicket.extensions.ajax.markup.html.modal.ModalWindow;
import org.apache.wicket.model.IModel;
public class FixedModalWindow extends ModalWindow {
private static final long serialVersionUID = 1L;
public FixedModalWindow(String id) {
super(id);
setResizable(false);
}
public FixedModalWindow(String id, IModel<?> model) {
super(id, model);
setResizable(false);
}
@Override
public FixedModalWindow setResizable(boolean resizable) {
// Cannot set resizable on the FixedModalWindow
return this;
}
@Override
public boolean isResizable() {
return false;
}
@Override
protected Object getShowJavascript()
{
// Hack in some JS to remove the onMove handlers
StringBuffer showJS = new StringBuffer();
showJS.append(" ");
showJS.append((String) super.getShowJavascript());
showJS.append("var popupWindow = Wicket.Window.get();\n");
showJS.append("var nullHandler = function() {};\n");
showJS.append("if(popupWindow != null) {\n");
showJS.append("popupWindow.bind(popupWindow.caption, nullHandler);\n");
showJS.append("popupWindow.bind(popupWindow.bottomRight, nullHandler);\n");
showJS.append("popupWindow.bind(popupWindow.bottomLeft, nullHandler);\n");
showJS.append("popupWindow.bind(popupWindow.bottom, nullHandler);\n");
showJS.append("popupWindow.bind(popupWindow.left, nullHandler);\n");
showJS.append("popupWindow.bind(popupWindow.right, nullHandler);\n");
showJS.append("popupWindow.bind(popupWindow.topLeft, nullHandler);\n");
showJS.append("popupWindow.bind(popupWindow.topRight, nullHandler);\n");
showJS.append("popupWindow.bind(popupWindow.top, nullHandler);\n");
showJS.append("}\n");
return showJS.toString();
}
}
如何在检票口的模态窗口中隐藏关闭按钮?我们找到了这样的解决方案:
ModalWindow yourModal = new ModalWindow("yourModalID") {
@Override
public void show(AjaxRequestTarget pTarget) {
super.show(pTarget);
pTarget.appendJavascript(""//
+ "var thisWindow = Wicket.Window.get();\n"//
+ "if (thisWindow) {\n"//
+ "$('.w_close').attr('style', 'display:none;');\n"//
+ "}"//
);
}
}
实际上,您可以从模态窗口插入任何类,并以某种方式对其进行更改。希望它可以帮助某人:)
