当我尝试清除模型时，它会第一次工作，但随后不会清除标签。
的HTML
在后面的代码中，我试图清除打字稿文件中的模型 this.tagsSelected = [];
这是第一次工作，但后来我似乎没有工作

不确定你是如何清除你的tagsSelected，但首先我建议让tagsSelect 2way绑定[(ngModel)]="tagsSelected"
<tag-input theme='bootstrap' id="test" [(ngModel)]="tagsSelected" [onlyFromAutocomplete]="true"
[clearOnBlur]="true" [maxItems]= "5" (onAdd)="onModelAdded($event)" (onRemove)="onModelRemoved($event)">
<tag-input-dropdown [showDropdownIfEmpty]="true" placeholder=""
[autocompleteItems]="sampleData">
</tag-input-dropdown>
</tag-input>
<button (click)="clear()">Reset</button>
<button (click)="pop()">pop</button>
<button (click)="add()">add</button>
组件：
import {Component,OnInit} from '@angular/core';
import {TagModel} from 'ngx-chips/core/accessor';
@Component({
selector: 'app-ngx-chips',templateUrl: './ngx-chips.component.html',styleUrls: ['./ngx-chips.component.css']
})
export class NgxChipsComponent implements OnInit {
tagsSelected: any [] = [];
sampleData: any;
constructor() {
this.sampleData = [
{display: 'A1',value: 'aA4'},{display: 'A2',value: 'aA3'},{display: 'A3',value: 'aA2'},{display: 'A4',value: 'aA1'},];
}
clear = () => {
this.tagsSelected = [];
}
add = () => {
const display = 'x_' + this.tagsSelected.length;
this.tagsSelected.push({display,value: display});
}
pop = () => {
this.tagsSelected.pop();
}
ngOnInit(): void {
}
onModelAdded = ($event: TagModel) => {
console.log(`$event`,$event);
}
onModelRemoved = ($event: TagModel) => {
console.log(`$event`,$event);
}
}
