当我在输入类型=“数字”中输入'e'字符时，数字将被放置在角度字段中

Question

I need to block the 'e' value that I can put in a input type number so this is my html file:

<input type="number" class="form-control" [(ngModel)]="money" name="money" required min="0" step="0.01" >

in my ts class

money:number;

Anyone can help me? I want block the possibility to insert the value 'e' in input type number.

You can use the keypress event on the input to prevent the entering of e . You'll have to create a method as a handler on your Component Class.

try this:

preventE(event) {
  if (event.which === 101) {
    event.preventDefault();
  }
}

Template:

<input 
  type="number" 
  class="form-control" 
  [(ngModel)]="money" 
  name="money" 
  required 
  min="0" 
  step="0.01" 
  (keypress)="preventE($event)">
