我是angular2中的新开发者,我想在json对象数组中进行全局搜索.例如,这个数组:
invoiceList =
[
{
invoiceNumber: 1234,
invoiceSupplier: "test",
invoiceStatus: "Import error",
invoiceCategory: "invoice with GR",
date: "22/01/2017",
amount : 134527
},
...
];
我想这样做我的搜索:
问题和困难在于:
我想仅根据某些值进行搜索(例如:状态,供应商名称,编号......)并显示其他字段(如日期,净金额等).
我想根据一些值(例如:数量,供应商,日期和金额)按最终结果排序.而且我不知道如何在angular2中做到这一点.
最后,我想在angular2中做一个"等效"的ng-show?我的意思是我只想按下搜索按钮才能显示表格,如果我们点击取消,它将删除它.
我知道在角度1中这样做很简单,我们可以使用过滤器,'orderBy'和类似的东西,但显然在angular2中,我们不能这样做而且我非常困惑.你能帮我解决一下吗???
这是我的组件代码:
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-search',
templateUrl: './search.component.html'
})
export class SearchComponent implements OnInit {
invoiceList = [{invoiceNumber: 1234, invoiceSupplier : "test", invoiceStatus : "Import error", invoiceCategory: "invoice with GR", date : "22/01/2017", amount : 134527},
{invoiceNumber: 15672, invoiceSupplier : "test11", invoiceStatus : "Import error", invoiceCategory: "invoice without PO", date : "02/01/2017", amount : 134.3},
{invoiceNumber: 99863, invoiceSupplier : "test22", invoiceStatus : "Other Document", invoiceCategory: "invoice with GR", date : "10/12/2016", amount : 189},
{invoiceNumber: 24561, invoiceSupplier : "test50", invoiceStatus : "Other Document", invoiceCategory: "invoice without PO", date : "15/01/2017", amount : -134527},
];
constructor() { }
ngOnInit() {
}
}
和我的HTML代码:
我知道到目前为止我没有做任何事情,但我在angular2时真的很新,我真的很困惑.你能帮助我至少与组件部分???
先感谢您 !
