phorman Posted May 17, 2008 Share Posted May 17, 2008 I have program that examines a specific directory, and under that directory is another directory of authors/Artists. Then inside the author/artist directory is all the songs, or lectures given by the individual or group. My program enters all the information into a Mysql Database (indexed) and allows for quick retrieval of requested content. My problem is that the inserting process can take some time, and therefore I want a way to be able to display the current status of the process. Here is what I have that I thought would work: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Untitled Document</title> <style type="text/css"> <!-- #status { height: 40px; width: 740px; background-image: url(template/images/bg_status.png); } #status #update { background-image: url(template/images/status.png); font-family: Arial, Helvetica, sans-serif; font-size: 24px; font-style: normal; font-weight: bold; color: #FFFFFF; height: 35px; padding-top: 5px; text-align: center; overflow: hidden; } --> </style> <script type="text/javascript" language="javascript" src="scripts/ajaxrequest.js"></script> <script type="text/javascript"> <!-- function updateProgress() { //MyAjaxRequest("none","batchmedia.php?action=process"); upd = document.getElementById("update"); do { MyAjaxRequest('status','batchmedia.php?action=show_status'); } while (upd.value != "100%"); } //--> </script> </head> <body> <div id="status" name="status"></div> <form> <input type="button" name="start" value="Start" onclick="updateProgress()" /> <div id="update" style="width:1%; "> 0% </div> </form> </body> </html> This is the output generated by the batchmedia.php?action=show_status call: <div id="update" style="width:100%; "> 100% </div> The percentages are passed using php code. This works, except I keep getting "Access Denied" or timeouts when this code runs. The errors usally take a few minutes to pop up, and then when I answer them, the solution works as expected. The error seems to come from : "An exception of type "Access denied was not handled"....... coming from: //located in ajaxrequest.js MyHttpRequest.open("get",url_encode(file +query_string),true); It should also be noted that this error is coming from Windows where no access is set on the file in the first place. After it works in my test environment, I will move it to my linux server environment and test again. Any help in this matter would be greatly appreciated. Additional Thoughts: May be its re-calling the script too soon, and some sort of pause should take place. I came to this after removing the loop and just running through it once. It worked without a problem. When I introduce the loop, is when it stops working correctly. Quote Link to comment Share on other sites More sharing options...
phorman Posted May 25, 2008 Author Share Posted May 25, 2008 I had another thought, and that was that maybe this is a limitation of ajax, and it would be better to use comet instead. I have tried all kinds of combinations and no success yet. I will attempt to implement comet, and see if that helps matters. Quote Link to comment Share on other sites More sharing options...
