IT 3215: Unit 04 Discussion DQ2 Challenges With Form Field Validation and Error Messages
Note: The
second discussion in each unit of this course is dedicated to community sharing
of challenges and solutions you have encountered while completing your weekly
assignment. You are encouraged to post and respond early in the week to share
experiences that you are having, and to help others with theirs. This is how
coders solve tough issues: they rely on one another!
Field
validation and its associated error messages are at the heart of creating an
effective form. It is important to both understand what information is required
in a form (and in which format), and anticipate the user’s experience.
Discuss one
or more of the challenges or experiences that you encountered when trying to
complete this week’s assignment. How did you try to address it or solve it?

Unit 04 Discussion
DQ1
Validating Form Input Data
Working
with and processing bad data generally means that a lot of work will have to be
done to clean up the data on the back end. To avoid the processing of bad or
incorrect data, we incorporate form validation into our Web pages. There are
numerous levels of data validation, from ensuring that input fields are not
empty to ensuring the user data entered conforms to a specified format.
Research
and describe some tips for someone new to JavaScript to get started. In
particular, focus on at least two of the following points while providing sample
code (with comments) of each:
How can we
set the focus to certain form elements? How do you check for empty input
fields?
What is the
purpose of using client-side validation versus server-side validation? Explain.
How does a
JavaScript function validate numeric and alphabetic inputs in specific fields?
How are
regular expressions used to match patterns with strings?
How can a
regular expression be used to validate data such as a Social Security number?
Under which
circumstances would you use a validation loop?
Why is
client-side validation prior to sending data to the server important?
What is the
potential problem of overly specific form validation?
How are the
+ operator and the \n escape sequence used when working with strings to
manipulate the DOM to add messages for errors?

Scholarly Resources: Scholarly resources are written with a focus on a specific subject discipline and usually written by an expert in the same subject field. Scholarly resources are written for an academic audience.
Examples of Scholarly Resources include: Academic journals, books written by experts in a field, and formally published encyclopedias and dictionaries.
Peer-Reviewed Journals: Peer-reviewed journals are evaluated prior to publication by experts in the journal’s subject discipline. This process ensures that the articles published within the journal are academically rigorous and meet the required expectations of an article in that subject discipline.
Empirical Journal Article: This type of scholarly resource is a subset of scholarly articles that reports the original finding of an observational or experimental research study. Common aspects found within an empirical article include: literature review, methodology, results, and discussion.
