By the end of this project, you will have written and tested JavaScript and HTML code that validates data values entered into input fields on an HTML form. Data validation is a valuable skill in web development. Notifying users of input errors not only improves the user experience it also helps to ensure that any data collected via a form is as accurate as possible before sending it to a server for processing. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

단계별 학습

작업 영역이 있는 분할 화면으로 재생되는 동영상에서 강사는 다음을 단계별로 안내합니다.

  1. Compare client- and server-side validation as you investigate when and where to validate data values to reduce data input errors.

  2. Use JavaScript code to check an input field on a form to ensure that it has been filled in and display an error message if the field is empty.

  3. Use JavaScript to test the value entered into a form field to determine its length and/or whether it falls within a range of numeric values and display an error message if that is not the case.

  4. Test the value entered into a form to ensure that it matches an email address format and display an error message if it does not.

  5. Modify HTML code to include built in form validation to check for a range of numbers, a list of values and the correct format for an email address.
