“metadataLoaded"的替代品是什么?在 JSONModel 中?

问题描述

在sap.ui.model.odata.v2.ODataModel中，有一个metadataLoaded 方法，我可以这样使用它:

In sap.ui.model.odata.v2.ODataModel, there is a metadataLoaded method which I can use it like this:

this.getModel().metadataLoaded().then( function() {
    var sObjectPath = this.getModel().createKey("/", {
        ID :  sObjectId
    });
    this._bindView("/" + sObjectPath);
}.bind(this));

JSONModel 似乎没有相应的方法，因为客户端模型中没有服务元数据概念.那么还有其他解决办法吗?

JSONModel doesn't seem to have a corresponding method since there is no service metadata concept in client-side models. So is there any other work around?

我尝试了 attachRequestCompleted.它没有按预期工作:

I tried attachRequestCompleted. It's not working as expected:

function bindview() {
    that._bindView(sObjectId);
}
this.getModel().attachRequestCompleted(bindview);

推荐答案

正如你所说的，没有元数据.但是对于 Json 模型，为什么要等待任何事件?可以直接绑定视图.

As you rightly said, there is no metadata. But for Json model why do you want to wait for any event? You can directly bind the view.
