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!

Dynamically populate multi-select combo box from another combo box.

Asked by nazzie303 in JScript, Scripting Languages

Tags: Javascript

I have seen various examples of populating cascading select boxes, but none for my situation.
Here is what I want to achieve. Lets take classic example of country and cities.

** I need two combo boxes on my page (Both Multi-select). One for country and one for cities.

** I will populate the Box1 with countries from the values from my database query and it shall be multi-select. Box 2 shall be empty.

** When user selects one or more countries from Box1 and hits a button (lets say a "Filter Cities" button), second combo box, Box2 shall get populated with the cities from the selected countries in Box1. This also needs to be multi-select. Also if the user sets focus on Box1 again, all the Box2 cities should be deleted, unless he hits the button again.

How do I achieve this with Javascript. I assume I shall be storing the country-city pairs in an array as well, from where the second box shall get populated.
