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!

Loading divs during onscroll

Asked by kmartin7 in Asynchronous Javascript and XML (AJAX), JavaScript, JScript

Tags: ,

I am trying to figure out a way to load divs with content using ajax (ie 6 & 7 only) when the user scrolls up or down. The idea is that the user will select an item from a point in a table of contents, and only that data will load (which works). But we are trying to make requests back to the server for more information if the user scrolls up or down. When a div comes into view, it will make a small request back to the server for the data to load. The issue we have is wireless bandwidth, and we don't want to load the entire page because the pages are quite large. Something like the following (ref id7); only fire an even whenever *each div* comes into the browser window:

<body>
<div style="height:150px;" id="id1">
id1
</div>
<div style="height:150px;" id="id2">
id2
</div>
<div style="height:150px;" id="id3">
id3
</div>
<div style="height:150px;" id="id4">
id4
</div>
<div style="height:150px;" id="id5">
id5
</div>
<div style="height:150px;" id="id6">
id6
</div>
<div style="height:150px;" id="id7" onscroll="fireEvent()">
id7
</div>
<div style="height:150px;" id="id8">
id8
</div>
<div style="height:150px;" id="id9">
id9
</div>
<div style="height:150px;" id="id10">
id10
</div>
<div style="height:150px;" id="id11">
id11
</div>
<div style="height:150px;" id="id12">
id12
</div>
<div style="height:150px;" id="id13">
id13
</div>
<div style="height:150px;" id="id14">
id14
</div>
<div style="height:150px;" id="id15">
id15
</div>
<div style="height:150px;" id="id">
id16
</div>
</body>
