私は(活字体/ Angular2/SPFXプロジェクトの一部)は、次のいる:TypeError例外:プロパティを読み取ることができません(観測可能な)未定義の '購読'
// Populate the regulatory documents dropdown
this.regulatoryDocumentsService.fetchRegulatoryDocumentsData().subscribe(
data => { this.regulatoryDocumentsData = data },
err => { window.console && console.log(err) }
);
:しかし
public fetchRegulatoryDocumentsData(): Observable<RegulatoryDocument[]> {
var choicesArray: Array<RegulatoryDocument> = new Array<RegulatoryDocument>();
// Local environment
if (Environment.type === EnvironmentType.Local)
{
// Send dummy data to the form - this works
window.console && console.log("fetchRegulatoryDocumentsData(): Local workbench in use");
choicesArray.push(new RegulatoryDocument(1,"Document 1"));
choicesArray.push(new RegulatoryDocument(2, "Document 2"));
choicesArray.push(new RegulatoryDocument(3, "Document 3"));
return Observable.of<RegulatoryDocument[]>(choicesArray);
}
else if (Environment.type == EnvironmentType.SharePoint ||
Environment.type == EnvironmentType.ClassicSharePoint)
{
// fetchRegulatoryDoocumentsData() is undefined. when I try to subscribe to it.
pnp.sp.web.lists.getByTitle('Regulatory Documents').items.get().then((choices: any[]) => {
window.console && console.log("choices ...");
window.console && console.log(choices);
if (choices) {
//choices.forEach((choice) => {
// choices.push(new Rating(choice));
//});
//Array.from(choices).forEach(function (child) {
// window.console && console.log(child)
//});
[].slice.call(choices).forEach(choice => {
choicesArray.push(new RegulatoryDocument(choice.ID, choice.Title));
});
}
return Observable.of<RegulatoryDocument[]>(choicesArray);
});
}
}
、 Environment.type != EnvironmentType.Local
の場合に問題が発生します。私が購読しようとすると、それは未定義に加入できないと言います。私はこれがネストされたPNPの約束のためだと思う。任意のアイデアを大いに感謝します
