[Solved] Given this Angular template snippet:<form #myForm="ngForm"> <input name="email" ngModel required pattern="^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,}$"> <button [disabled]="myForm.... | Angular

Angular - Template-Driven Forms

Given this Angular template snippet:

<form #myForm="ngForm">
  <input name="email" ngModel required pattern="^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,}$">
  <button [disabled]="myForm.invalid">Submit</button>
</form>

What happens when the user types 'user@example' and tries to submit?

AThe form resets automatically.

BThe form submits successfully because 'required' is satisfied.

CThe submit button is enabled but submission fails with an error.

DThe submit button remains disabled because the pattern is not matched.

Step-by-Step Solution

Solution:

Step 1: Analyze the pattern validation
The pattern requires a valid email format with a domain suffix. 'user@example' lacks the '.com' or similar suffix, so it fails pattern validation.
Step 2: Check form validity and button state
Since pattern validation fails, myForm.invalid is true, disabling the submit button.
Final Answer:
The submit button remains disabled because the pattern is not matched. -> Option D
Quick Check:
Pattern mismatch disables submit button [OK]

Quick Trick: Invalid pattern disables submit button via form.invalid [OK]

Common Mistakes:

MISTAKES

Assuming 'required' alone enables submit
Thinking form submits despite pattern failure
Expecting automatic form reset on invalid input
