Unit 4 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?
Describe the use of the Document Object Model in JavaScript applications.
Describe these events for working with controls: onfocus, onblur, onclick, ondblclick, onchange, onselect.
Describe the process of creating and adding nodes to the DOM, including adding rows and cells to a DOM table.
Distinguish between a function expression and a function declaration, including which one can be called before it is defined.
Note: The second discussion in each unit of this course is dedicated to community sharing of challenges and solutions encountered while completing your Unitly assignment. You are encouraged to post and respond early in theUnit 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!
Creating and employing variables for the first time can be tricky. Putting them in a form can make it even tougher. For some it is very intuitive; for others, less so.
Discuss one or more of the challenges or experiences that you encountered when trying to complete this Unit’s assignment. How did you try to address it or solve it?
