angular5 的颜色有多奇怪
how color odd even with angular5
我,这是我的日历小时模板:
<ul class="heure" *ngFor="let heure of libelleTranche; let even = even; let odd = odd" [ngClass]="{ odd: odd, even: even } ">
<li >{{ heure }} H</li>
</ul>
我想在 less:
中应用这个 css
.heure{
li{
float: left;
width:2.5em;
}
}
.even { background-color: red; }
.odd { background-color: green; }
我的结果是:
Lun
10 H
11 H
12 H
13 H
14 H
15 H
我会显示时间添加和事件以获得更多可见性
我的组件在这里:
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-heure',
templateUrl: './heure.component.html',
styleUrls: ['./heure.component.css']
})
export class HeureComponent implements OnInit {
trancheDeb = 0;
trancheFin = 24;
libelleTranche=new Array(); //calculé fin de tranche - debut de tranche
constructor() {
let plageJour = this.trancheFin - this.trancheDeb;
for(let i=0;i<plageJour;i++){
this.libelleTranche.push(i);
}
console.log(this.libelleTranche);
}
}
我必须如何为奇数和活动时间正确涂色?
感谢回复:)
even
和 odd
由 ngFor
指令提供的变量基于 currentElement index
。对于您的情况,您应该根据 (heure % 2)
计算结果设置 odd
& even
值。
<ul class="heure"
*ngFor="let heure of libelleTranche"
[ngClass]="{ odd: (heure%2 == 0), even: heure %2 == 1 } ">
<li >{{ heure }} H</li>
</ul>
<ul class="heure" *ngFor="let heure of libelleTranche; let even = even; let odd = odd" >
<li [ngClass]="{ odd: odd, even: even } ">{{ heure }} H</li>
</ul>
