HTML5 Forms: JavaScript and the Constraint Validation API
Article Introduction：Core points
HTML5 allows client form validation to be free of JavaScript encoding, but for more complex forms, JavaScript and constraint validation APIs can be used to enhance native validation. This is because of some limitations, such as not all browsers support all HTML5 input types and CSS selectors, and it is difficult to style the error message bubble.
The Constraint Validation API provides some methods and properties, such as .willValidate, .checkValidity(), .validity, and .setCustomValidity(). These are used to check whether the verification field is to be validated, the verification field is to be validated, and to set the validity of the field.
