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!

AJAX for beginners

Asked by Finduilas in JavaScript, PHP Scripting Language

Tags: ,

Hi.

I'm building a webpage that uses AJAX to connect to a PHP server and send a series of sql statements to that server. However I havent found a method to take the xmlhttp.open outside my for loop, so my performance is bugged. What am I doing wrong here?

So what is needed to bring my xmlhttp.open outside the javascript for loop in order to keep the connection to the server open and just call the same php page over and over again?

<html>
<head>
<script language="javascript">
function pageonload()
{
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
for (i=0; i<10;i++)
{
xmlhttp.open("POST", urltophp, false);
xmlhttp.send();
str = xmlhttp.responseText;
alert(str);
}
}
</script>
</head>
<body onload="pageonload()"/>
</html>

And the php:

<?php
echo "Hello from php";
?>
