我发送一个这样的事件进行删除

<child-component *ngFor = "#todo of array" [taskobject] = "todo" 
(childevent) = "deleteparent($event)">Loading...</child-component>

我如何与 childevent 一起发送另一个事件，它是用逗号分隔的吗？像这样？

<child-component *ngFor = "#todo of array" [taskobject] = "todo" 
(childevent) = "deleteparent($event)", 
(updateevent)> = "(updateparent)"Loading...</child-component>

对于编辑/更新请求，我应该向服务器请求什么 http，它是 http.put 也在服务器端吗，它是 server.put('url') 吗？

更新：

<child-component *ngFor = "#todo of array" 
[taskobject] = "todo"   (childevent) = "deleteparent($event)"
; (updatevent) = "updateparent($event)">Loading...</child-component>

I think you want to handle multiple events on the same element. If so, list the event handlers separated by space, just as you would with regular HTML attributes:

<child-component *ngFor = "#todo of array" [taskobject] = "todo" 
   (childevent) = "deleteparent($event)" 
   (updateevent) = "updateparent($event)">Loading...</child-component>

您应该将它们分开，;但条件是如果第一个表达式出错，它将不会评估下一个表达式。但在你的情况下，这两个都是函数，所以它会按预期运行：

(anyevent)="function1($event);function2($event);etc"

这也适用于&&这样的符号：

(anyevent)="function1($event)&&function2($event);etc"

试试吧。希望这可以帮助你。

请改用

(childevent)="deleteparent($event);updateparent($event)"
