访问NgClass中的HTML元素值

Question

so i would like to retrieve the value of an html input inside it's ngClass to compare it later in a pipe . Exemple :

<input type="email" ... [ngClass]="myPipe(input.value)" >

Or maybe like this :

 <input type="email" ... [ngClass]="item.value | myPipe" >

Do you know any way of achieving this ?

Thanks .

Answer 1

从我上面的评论复制：

<input type="email" #myInput [ngClass]="myPipe( myInput.value )" >

Answer 2

尝试这个：

<input type="email" [ngModel]="input.value" [ngClass]="myPipe(input.value)" >
