ngfor如何在Angular 8中设置动态function？

Question

i have this in my html component:

<div>
    <button (click)="myFunction1()">myFunction1</button>
</div>
<div>
    <button (click)="myFunction2()">myFunction2</button>
</div>
<div>
    <button (click)="myFunction3()">myFunction3</button>
</div>

and in typescript:

myFunction1()
myFunction2()
myFunction3()

but i try to do something like this, but it's not working!

typescript component:

var myFunctions = [
"myFunction1",
"myFunction2",
"myFunction3"
]

html component:

<div *ngFor="let myFunction of myFunctions">
    <button (click)="myFunction()">{{myFunction }}</button>
</div>

Know someone what the solution?

Answer 1

Do you want the function to execute on the button click? Just use the array to hold reference to the functions.

// *.ts
const myFunctions = [
  myFunction1,
  myFunction2,
  myFunction3
]

Then in your template you can bind the click event to the function.

// *.html
<div *ngFor="let myFunction of myFunctions">
    <button (click)="myFunction()">myFunction</button>
</div>

Your example above is just binding the click to a string.
