我要评论在项目开发中拿到的数据是这样的，要循环遍历出来。可是在ng2中好像不能直接遍历object
datas: any = [
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24"},
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24"},
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24"},
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24"},
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24"},
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24"},
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24"},
];
在搜索之后发现了这种方法可以实现。
array-ngfor.ts
import { component } from '@angular/core';
@component({
selector: 'page-array-ngfor',
templateurl: 'array-ngfor.html',
})
export class arrayngfor {
constructor() { }
datas: array<any> = [
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24" },
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24" },
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24" },
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24" },
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24" },
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24" },
{ num: 1, date: "2017-04-12", sellnum: "1231234", sellmpney: "1233", returnnum: "24" },
];
getkeys(item) {
return object.keys(item);
}
}
array-ngfor.html
<ion-header>
<ion-navbar>
<ion-title>关于ngfor 嵌套循环</ion-title>
</ion-navbar>
</ion-header>
<ion-content>
<ion-row *ngfor="let item of datas">
<ion-col *ngfor="let key of getkeys(item)"> {{ item[key] }}</ion-col>
</ion-row>
</ion-content>
重点的是这个方法
getkeys(item){
return object.keys(item);
}
结果：
