angular2表单验证问题

Question

求问如何判断2个输入框同时输入内容后改变登录按钮颜色

Answer 1

可以通过这两个input的value来做判断啊，如果两个value都非空，就让button的disabled属性为false，否则为true

Answer 2

<input [(ngModel)]="name" (ngModelChange)="onchange()"/><input [(ngModel)]="pwd" (ngModelChange)="onchange()"/><button [disable]="isDisable" (click)="onLogin()">登录</button>isDisable=true;name='';pwd='';onchange(){&nbsp; &nbsp; if(name.length>0&&pwd.length>0){&nbsp; &nbsp; &nbsp; &nbsp; this.isDisable=false;&nbsp; &nbsp; }else{&nbsp; &nbsp; &nbsp; &nbsp; this.isDisable=true;&nbsp; &nbsp; }}自己写CSS来控制Button是否可用时的样式
