ngFor 中的字符串插值 (click)="..."

Question

像这样在 ngFor 中循环遍历数组：

<div *ngFor="account of accounts">
    <button (click)="function1(); account.message='How do I interpolate {{account.something}} here'"
</div>

我收到错误消息 Got interpolation ({{}}) where expression was expected 如果我只做 account.something 而没有插值，因为它在单引号之间，它将打印为文字 How do I interpolate account.something

Answer 1

只需使用字符串连接，如：

(click)="account.message='How do I interpolate ' + account.something + ' here'"

Answer 2

你已经打算在双引号里面写javascript，所以你不需要写插值语法。

(click)="All javascript code can be written here without interpolation syntax"

ngFor 中的字符串插值 (click)="..."

String interpolation inside ngFor (click)="..."

javascript
