我试图将我们使用的html模式组件化。 html看起来像这样
function mapper(array) {
return array.map(function(i) {
i.Domain = i.Domain.toLowerCase();
return i;
})
}
var array = [
{ "Name" : "Bill",
"Domain" : "TEST.com",
},
{ "Name" : "John",
"Domain" : "JohnTest.com",
},
{ "Name" : "Fred",
"Domain" : "fredtest.com",
}
]
var newArray = mapper(array);
console.log(newArray); /*[ { Name: 'Bill', Domain: 'test.com' },
{ Name: 'John', Domain: 'johntest.com' },
{ Name: 'Fred', Domain: 'fredtest.com' } ]*/
打字稿代码看起来像这样
<input class="sidebarInputDevice" type="search" [list]="listidentx" placeholder="Search {{label}}..." (input)="deviceSelected($event.target.value)"> {{listidentx}}
<datalist [id]="listidentx">
<option *ngFor="let item of items">{{item.name}}</option>
</datalist>
我收到以下错误
import { Component, OnInit, EventEmitter, Input, Output } from '@angular/core';
@Component({
selector: 'app-select-entry',
templateUrl: './select-entry.component.html',
styleUrls: ['./select-entry.component.css']
})
export class SelectEntryComponent implements OnInit {
constructor() {
//this.listidentx='working';
}
@Input()
items:{}[] = [];
@Input()
label = '';
@Input()
listident='custom';
listidentx = 'bacon';
@Output()
valueChange: EventEmitter<number> = new EventEmitter();
ngOnInit() {
console.log(this.items);
console.log("-----");
for (var i=0;i<this.items.length;i++) {
console.log(this.items[i]);
}
console.log("^----");
}
valSelected(value) {
this.valueChange.emit(value);
}
}
是否有解决方案,或者我不能使列表属性动态化。
如果我无法使属性动态,我可以确保每个组件的列表都有不同的ID。
答案 0 :(得分:1)
要绑定到元素属性:
<input [attr.list]="listindent">
如果listident='custom'
,在运行时它将如下所示:
<input list="custom">
