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!

parseInt not working for me

Asked by georgesmay in JavaScript

Tags: ,

I have different scripts working here. The first simple script copy's the form field "price" and pastes it into "total" with an onblur event.

The next script converts the currency over to either dollar, or the Canadian dollar. It fires off with an onchange event when a selection is made.

The problem is when it copies the number over from price it seems to be a string. Therefore the result is NaN. However, if i type the number into the total box and then make a selection it works. I've attached all the code im working with below.  The commented out sections are me testing a few different things.

I've also tried adding parseInt ... However, i dont think im putting it in the right place as im getting the same result.Start Free Trial
