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!

Passing Javascript variables to ColdFusion

I found a solution that works without any redirects or page refresh to get Javascript variable into ColdFusion.  

Here is the code I used to obtain the page title and put into session variable:
<cfset session.PageTitle = "<script language='JavaScript'>document.write (document.title); </script>">

You can pass values from browser to web server only by URL, or by Cookie, or by Form submit date. There is NO other way beside that.

So generaly in one page display you cannot flush the html page source to the browser and read at the flush time the script results of browser side evaluation.

I assume you did something like this:
<cfoutput>#session.PageTitle#</cfoutput>

And you was happy to see your Page Title!

But look at the page source on the browser side. You will see this:
<script language='JavaScript'>document.write (document.title); </script>

And that is exactly what you stored into CF session.PageTitle
So you did not store the PageTitle but the <script> that displays the page title when executed on browser side.

On CF side you have always the same String: <script language='JavaScript'>document.write (document.title); </script>

Accepted Solution

Yep, I spoke too soon as it displayed the title value on the webpage but when trying to pass the page title into a database, it gave me the javascript. Oops, but at least it was a good excersize for me.
