Full Stack JavaScript Techdegree Student 4,160 PointsDemo Video Doesn't Match The Directions
This practice is confusing because in the demo video, form elements are being validated while they're being typed in, showing the validation icon, requiring a 'blur' event on each input separately. However, the directions are requiring a 'submit' event.
When using the submit event it's default is to clear out the form and refresh, so there's no way to see if it's valid with the green checkbox as shown in the video.
To see the validation symbols, add e.preventDefault() as the first line in the addEventListener(). This will prevent it from submitting the form if correct but it will show you the validation icons.
To add to the confusion, in the second video solution the e.preventDefault() is only added to the else portion of the if clause, only stopping if there's an error. This only shows the valid icon if one of the other inputs are invalid.
