我是Angular2的新手,并且我试图从输入中将新项添加到列表中。但是然后单击以提交我,而不是文本[object Object]。
这是我的代码:
app.component.html
<form (submit)="addItem(item)">
<md-input-container>
<input [(ngModel)]="name" mdInput placeholder="add" name="addNew">
</md-input-container>
<button type="submit" md-icon-button>
<i class="material-icons">send</i>
</button>
</form>
app.component.ts
items = Players;
name;
addItem(name): void {
this.items.push(new Player({
name : name
}));
}
玩家
export class Player {
id: number;
name: string;
count: number;
constructor(name){
this.id;
this.name = name;
this.count = 0;
}
所有玩家
export let Players: Player[] = [
];
谢谢你的回答

我会写一个完整的答案。
在您的组件(TS文件)中:
items = Players;
name;
addItem() { this.items.push(new Player({ name : this.name })); }
在您的HTML中:
<form (submit)="addItem()" novalidate>
<md-input-container>
<input [(ngModel)]="name" mdInput placeholder="add" name="addNew">
</md-input-container>
<button type="submit" md-icon-button>
<i class="material-icons">send</i>
</button>
</form>
我的猜测是您提交了2次表格。
