我尝试在angular 2应用程序中实现ng-class-even和ng-class-odd(从angular 1开始)类型的行为。
我已经在下面编写了代码,并且可以正常工作,我想知道是否还有其他方法可以做到这一点。
的HTML
<div *ngFor="#employee of employees; #index = index" [class.odd]="index%2==1" [class.even]="index%2==0" [class.selected]="employee === selectedEmployee">
<p>{{employee.name}}</p>
</div>
的CSS
.odd {
background-color: #f2f9ff;
}
.even {
background-color: #eceff3;
}
最佳答案
旧方式
DEMO :http://plnkr.co/edit/YkcudQipF1c8iT5LCRyd?p=preview
<div *ngFor="#employee of employees;
#index =index;
#isOdd=odd;
#isEven=even"
[class.odd]="isOdd"
[class.even]="isEven"
[class.selected]="employee === selectedEmployee">
<p>{{employee.name}}</p>
</div>
新方法
用替换
#
let
(关键字)<div *ngFor="let employee of employees;
let index =index;
let isOdd=odd;
let isEven=even"
[class.odd]="isOdd"
[class.even]="isEven"
[class.selected]="employee === selectedEmployee">
<p>{{employee.name}}</p>
</div>
