Unit 05 Discussion

DQ1 Cookies: Storing and Passing Information

On their own, HTML and CSS are unable to store user information, so once the Web browser is closed, any user information is lost. Cookies, Web storage, and sessions are workarounds for this shortcoming. Research and describe some tips for someone new to JavaScript to get begin to work with user information storage. In particular, focus on at least two of the following points while providing sample code (with comments) of each:

o Identify which storage situations would be best resolved with sessions, local storage, and cookies to store persistent data.

o Distinguish among session storage, local storage, and cookies.

o Describe how to create, read, and delete cookies with the document.cookie property.

o Explain how to parse a cookie string.

o Describe the visibility, scope, and lifetime of a cookie.

o Explain how cookies can create a customized user experience.

DQ2 Challenges with Query String and Storing Persistent Information

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!

Modern Web sites rely increasingly on processing queries. Saving that data and passing it along to other Web pages is just as important.

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?

Response Guidelines

Comment on the posts of at least two other learners. Share suggestions to help them address their challenges.
