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!

JavaScript function doesn't work when html control in asp.net server control

Asked by Sanmarie in Programming for ASP.NET, JScript, Hypertext Markup Language (HTML)

Tags: asp.net 3.5, javascript, server, html control, visual studio 2008, ie 6.0

Using asp.net 3.5, visual studio 2008, javascript, Using IE 6.0

I have an asp.net page with an input tag in a body tag. I want to call a javascript function in an external javascript file. The function should set the value of the input tag to the users computer name when the window loads. I notice that in certain scenarios, it doesn't work.  When I put runat="server" on the body tag and set the onload event to call the function in the external  javascript file, it gives an error.  When I remove the runat=server and put onload="getComputer" directly on the body tag, it works.

Please help me as I thought I understood Javascript and now I'm not so sure.
