TEMPLATE DRIVEN FORMS IN ANGULAR #quicke

Angular reads the html template, and see the form tag as a special case

We want angular to handle the submit of the form which will be triggered by the button of type ‘submit’ present inside the form

We listen to that event by placing (ngSubmit) on the form selector.

A reference with the hash symbol can be placed on the form selector, to create a reference to the form.

That reference should be set to ngForm.

The created reference can be passed for processing inside theTypsecript code, by mentioning it as an argument to the function which is bind to ngSubmit event like :

<form (ngSubmit)=“submitFunction(formRef)” #formRef=“ngForm”>

Above form object can also be referenced inside typescript code using Viewchild.

@ViewChild(’formRef’) formRef:NgForm

The controls present inside the form which angular should consider as part of the form object must have ngModel as a directive.

[ngModel] can be used to assign a default value to the controls inside the form.

[(ngModel)] can be used to create two way binding.

 The properties in the form object will have name as that of the value specified by ‘name’ attribute of html elements.

The properties can be grouped inside a form object using ngModelGroup

The reference to the html elemnents can be created, like below

<input type=“text” name=“username” ngModel #username=“ngModel”>

The reference for the model groups can be created as below

<div ngModelGroup #someModelGroup=“ngModelGroup”> <input type=“text” name=“username”/> <input type=“text” name=“firstName”/> </div>

The form, elements which are have ngModel directive and the groups, all have properties like touched, dirty, valid, invalid, which can help in validating the form

For enabling HTML5 validations which might be disabled by default, place ngNativeValidate on form.

setValue method of ngForm can be user to set the value of complete form and it is directly available on ngForm object.

pathValue can be used to update the partial value of the form and it is available on form property of the ngForm object,(not directly on ngForm)

reset() function on the ngForm can be used to reset the form, which will clear everything.

If reset means setting default value, one can use patch value for the same
