我正在从视图>类别生成面板,因此面板数量未知。因此,我无法将具体的内容分配给他们。
当我展开面板时,我需要关闭所有其他面板,那么如何确定如何识别其他面板以关闭它们?
我不能使用byId,那么我可以使用JQuery搜索吗?
<List id="idList" items="{view>/categories}">
<items>
<CustomListItem>
<Panel expandable="true" expanded="false" headerText="{view>categoryDesc}" onExpand="onExpand">

我会通过绑定(将另一个属性“expand”)添加到类别中,类似于:
视图:
<List id="idList" items="{view>/categories}">
<items>
<CustomListItem>
<Panel expandable="true" expanded="{view>expanded}" headerText="{view>categoryDesc}" expand="onExpand" />
控制器:
onExpand: function(oEvent) {
if (oEvent.getParameters().expand) {
var oModel = this.getView().getModel("view");
var aPath = oEvent.getSource().getBindingContext("view").getPath().split("/");
var selectedIndex = +aPath[aPath.length - 1];
var aCategories = oModel.getProperty("/categories");
for (var i = 0; i < aCategories.length; i++) {
if (i !== selectedIndex) {
aCategories[i].expanded = false;
}
}
oModel.updateBindings();
}
},
并且不要忘记初始化“扩展”属性......

@SergeiVavilov值得称赞我指出了正确的方向。
这是他的手风琴解决方案的更新版本,带有完整的工作代码,可以互锁多个面板的展开状态,此外还可以点击面板标题。这使得手风琴处理更直观。
