使用Form报错提示If ngModel is used within a form tag, either the name attribute must be set or the form

<form>
    <div>
        <input type="text" [(ngModal)]="value" >
    </div>
    <div>
        <button>保存</button>
        <button>取消</button>
    </div>
</form>

会报错

If ngModel is used within a form tag, either the name attribute must be set or the form

解决办法：

在绑定了ngModel的地方加入name属性即可

<form>
    <div>
        <input type="text" [(ngModal)]="value" name="fieldName">
    </div>
    <div>
        <button>保存</button>
        <button>取消</button>
    </div>
</form>
