我有项目列表,我想一次触发一个项目的状态。 http://plnkr.co/edit/WGLbs2gl7zSxGymOSm0y?p=preview
点击时我只想点击项目以获取状态,如果状态为“已关闭”,则不应显示。
<md-card *ngFor="let item of items">
<md-card-title (click)="showDetails()">{{item.name}}</md-card-title>
<md-card-content [@state]="closed">state = {{state}}
<p>{{item.hair_color}}</p>
<p>{{item.skin_color}}</p>
<p>{{item.eye_color}}</p>
</md-card-content>
</md-card>
moment.updateLocale
答案 0 :(得分:1)
或多或少通过传递项目并在项目上显示状态... http://plnkr.co/edit/QhArVlfFGIsXjx5QSLcX?p=preview
来计算出来function euler(n) {
let zero = new Decimal(0);
let one = new Decimal(1);
let rval;
for (let i = 0; i <= n; i++) {
let fval = factorial(i);
let invert = one.dividedBy(fval)
zero = zero.plus(invert)
}
rval = zero.toFixed(Number(n))
return rval;
}
function factorial(n) {
var i = 2,
r = new Decimal(1);
for (; i <= n; r = r.times(i++));
return r;
}
希望它可以帮助别人:)
