【问题描述】：
我正在使用 Angular-DataTables 6.0（在此处找到 https://l-lin.github.io/angular-datatables/#/welcome）并且我遇到了一个反复出现的问题。添加或删除表项时，记录在排序或搜索时消失或重新出现。这可能是因为添加/删除是从数据表外部发生的吗？
我已尝试添加许多其他建议的“datatable="ng" 修复程序，但这并没有改变任何内容。我还尝试添加重新渲染功能，但在这种情况下，我遇到了无法解决的“对象取消订阅”错误。作为参考，一些类似的问题可以在这里找到：类似的例子包括：（angular : lost data after sort datatable） (Sorting of numbers within brackets in angular datatables) (https://github.com/l-lin/angular-datatables/issues/852)
这是我的代码：
HTML:
<table datatable="ng" [dtOptions]="dtOptions" [dtTrigger]="dtTrigger" class="table table-hover" id="t1">
<thead>
<tr>
<th>
<button id="b5">Asset ID</button>
</th>
<th>
<button id="b5">Employee ID</button>
</th>
<th>
<button id="b5">Asset Type</button>
</th>
<th>View</th>
<th>Delete</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let a of assets; let i = index">
<td>{{ a.assetID }}</td>
<td>{{ a.currentUser }}</td>
<td>{{ a.assetType }}</td>
<td><button id="button1" (click)="viewAsset(a)"><i class="fas fa-search"></i></button></td>
<td><button id="b2" class="btn" (click)="scrapAsset(a)" (mouseenter)="buttonHover(i)" (mouseleave)="buttonHoverLeave(i)"><i class="{{buttonIconArray[i].text}}"></i></button></td>
</tr>
</tbody>
</table>
-elsewhere in the code-
<button class="btn" id="b1" (click)="addAsset()">Add New Asset</button>
TS
dtOptions: DataTables.Settings = {};
dtTrigger = new Subject();
addAsset()
{
this.confirmChanges = false;
//Create a new asset:
let a: Asset = {
assetID: this.assetID,
currentUser: this.currentUser,
assetType: this.dropdownMessage,
}
//send a notification to the user that owns the new asset
let notify: Notice = {
emplyID: a.currentUser,
notificationSource: "Asset",
details: "A new " + this.dropdownMessage + " was added to your assets.",
timeStamp: new Date()
}
//Add the asset to the server
this.AssetsService.addAsset(a)
.subscribe(asset => { this.assets.unshift(asset);
//All of the inputs need to be emptied
this.clearFields();
})
}
scrapAsset(a: Asset)
{
console.log("The ID is " , a.assetID)
//this.AssetsService.deleteAsset(this.currentAsset).subscribe()
this.confirmChanges = false;
//This deletes the asset from the back-end.
this.AssetsService.deleteAsset(a).subscribe(() => {
console.log('test')
this.assets = this.assets.filter(t => t !== a);
this.NotificationsService.addNotice(notify).subscribe();
this.clearFields(); });
}
dtActivate()
{
this.dtOptions = {
pagingType: 'full_numbers',
pageLength: 7,
order: (this.assets.assetType),
orderClasses: false,
};
this.AssetsService.getAssetsIT().subscribe((assetsImported) => {
this.assets = assetsImported;
this.parseData();
// Calling the DT trigger to manually render the table
this.dtTrigger.next();
});
}
