The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Generate form fields from a drop down menu

Asked by InnerChild in JavaScript

Tags: Java Script, Ajax, PHP

Initially I had the following questions going  http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q_23335795.html#discussion
What this solution provides is that when a person selects a number in the drop down then some form elements are dynamically created.

The problem I am having is that when submitting the form the only information that is being parsed is the number that is selected and not the information that is entered into the text boxes.

Also I now need to add a radio group as well to the group of elements that are created.

So as an example......

A Person clicks on 2 in the drop down then the fields that need to be dynamically created are...
Person 1 name
Person 1 email
Person 1 radio group
option 1
option 2
option 3

Person 2 name
Person 2 email
Person 2 radio group
option 1
option 2
option 3

And all the information entered submitted (name, email, and the option chosen) via email.
Thanks,


IC
