ngFor（click）=＆＃34; ...＆＃34;内的字符串插值

Question

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Got interpolation ({{}}) where expression was expected 如果我只是account.something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：

$date = "4/20/2019";
if( validateDateFormats($date, 'm/d/Y')
    ||  validateDateFormats($date, 'n/d/Y') ){
    print "This date is valid."; 
}

Answer 2

你已经在双引号内写了javascript，所以你不需要编写插值语法。

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