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：
