Angular requires that a “name” attribute be set on an input element when using the ngModel directive within a form. To resolve If ngModel is used within a form tag, either the name attribute must be set or the form error, simply add the “name” attribute to the input element. This allows Angular to bind the input element to a form control, which is necessary for form validation, data tracking, and other features related to forms in Angular. When using the ngModel directive within a form element, you must either set the name attribute of the form control or bind the ngModel directive to a property of the component, according to the error message.
The complete error you might be getting:
Exception Message: NG01352: If ngModel is used within a form tag, either the name attribute must be set or the form.
Fix: Make sure you are not missing the name attribute in your control.
Using the following example, you can set the name attribute:
<form>
<input [(ngModel)]="yourProperty" name="yourControl">
</form>Above, The ngModel directive binds the value of an HTML input element to a component property. The syntax [(ngModel)] indicates two-way data binding: changes made to the input element will update the component property, and changes made to the component property will update the input element.
When you use the ngModel directive in a form element, such as the [(ngModel)]
tag in this example, the name attribute is used to assign a unique name to the form control. This is necessary for Angular to track the value and validation status of the input element as part of the form.
In this example, the value of an input element is bound to a component property using the ngModel directive. The input element is also given a name with the name attribute. This enables Angular to track the value and validation status of the input element as part of the form, which in turn enables features such as data tracking and form validation.
