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!

Need help with constructing an innerHTML reference

Asked by saabStory in JavaScript

I'm making an interface based on an image map.  When you mouseover one of the countries or click on one of the column heads, you see a list of countries drop down.  As it sits right now, the heading of the dropped column remains a link.  What I want to do is to re-write the inner HTML of the div to not be a link for the selected column/country.  I'm having trouble writing the reference though.  I thought I could take the div id from the array I was polling, add a one (1) to the end of it to refer to the div I'd like to change but I keep getting a syntax error.

If anyone could tell me what I'm doing wrong and how to fix it, I'd greatly appreciate it.

Thanks much in advance.Start Free Trial
