得到错误'WinJS.Utilities.requireSupportedForProcessing' [英] getting error 'WinJS.Utilities.requireSupportedForProcessing'

问题描述

场景 - 我想根据AppBar上实施的搜索条件刷新split.html上显示的项目。所以我在事件处理函数中声明地执行此操作

Scenario - I wants to refresh the items displayed on split.html based on the search criteria implemented on AppBar. So i am doing this declarativly in event handler function

我在AppBar菜单命令的"点击"时附加了函数作为事件处理程序。

I have attached function as event handler while 'click' of AppBar menu command.

在函数中;

{

listView.itemDataSource = filteredItems.dataSource;

listView.itemDataSource = filteredItems.dataSource;

}

执行此函数后，获取以下异常：

after this function got executed , getting exceptions of these :

WinJS.Utilities.markSupportedForProcessing

  WinJS.Utilities.requireSupportedForProcessing;

WinJS.Utilities.markSupportedForProcessing
  WinJS.Utilities.requireSupportedForProcessing;

我将此异常绑定，并获得信息 - 需要使用以上两个属性注册事件处理程序。但我仍然得到同样的例外。请在这里帮助我。

I binged this exception and , got info - needs to register the event handler with above two properties. But still i am getting the same exception. Please help me here.

推荐答案

如果你在HTML中使用声明性函数，您需要在JavaScript事件处理程序代码中使用markSupportedForProcessing：

If you use declarative functions in HTML, you need to use markSupportedForProcessing in the JavaScript event handler code:

例如（代码来自其中一个项目模板）：

For example (code is from one of the project templates):

var util = WinJS.Utilities;

var util = WinJS.Utilities;

section3ItemNavigate：util.markSupportedForProcessing（function（args）{

    //做东西

section3ItemNavigate: util.markSupportedForProcessing(function (args) {
    // do stuff

    nav.navigate（" /pages/item/item.html"，{item：item}）;

}） ，

    nav.navigate("/pages/item/item.html", { item: item });
}),
