如何在 SAPUI5 中的 Controller 中设置 List 的排序器? [英] How to set sorter of a List in Controller in SAPUI5?

问题描述

这基本上是这里问题的解决方法试验:如何在 XML 视图中使用自定义排序器"

This is basically a workaround trial for the question here : "How to use custom sorter in XML views"

由于目前无法在 XML 视图中使用自定义排序器，我想也许可以在控制器中设置排序器.

Since currently it is not possible to use custom sorters in XML views, I thought maybe it is possible to set the sorter in the controller.

您如何使用 JS 视图执行此操作:

How you do that with JS view is like this:

var oTemplate = ... // irrelevant

var oList = new sap.m.List({
    id: this.createId("someList"),
    items: {
        path: "/list",
        template: oTemplate,
        sorter: foo.bar.CustomSorter
    }
});

当我想将其转换为 XML 视图时，我有以下内容:

And when I want to convert that to and XML view, I have the following:

<m:List id="someList"
        items="{path: '/list'}">
    <!-- hid ListItem implementation -->
</m:List>

那么，如何在控制器中为这个列表设置一个排序器?还有，在哪里挂?选项:

Then, how can I set a sorter to this list in controller? Also, where to hook it? Options:

• onInit
• onBeforeRendering
• onAfterRendering

所以，我的预期是这样的:

So, what I expected was something like:

sap.ui.controller("foo.bar.controller.SomeController", {
   onInit : function(){
      var oList = this.getView().byId("someList");
      oList.get___Something___().setSorter(foo.bar.CustomSorter);
   };
};

但似乎不可能.

推荐答案

onInit 应该没问题.

onInit should be fine.

使用 List 的方法 bindItems绑定项目并应用排序器.

Use List's method bindItems to bind the items and apply the sorter.

类似于:

oList.bindItems('/list', ListItemTemplate, foo.bar.CustomSorter);

oList.bindItems('/list', ListItemTemplate, foo.bar.CustomSorter);
