Hi, I am using AJAX and php for creating a small UI that retrieves data from mysql upon clicking on one button. But i clicked on that , nothing is happening. Below is my index.html : *-- index.html * <html> <head> function week_report_fun(){ var ajaxRequest; --- --- -- ajaxRequest.open("GET","ajaxex.php?q="+users,true); ajaxRequest.send(); } </script></head><body> <form> User : <select id="users" onchange="week_report_fun()"> <option value="">Select a user</option> <option value="133">av</option> <option value="168">ad</option> <option value="78">so</option> <option value="239">ak</option> </select></form><br> <div id="txtHint"><b>Person info will be listed here.</b></div> </body></html> *Access Log Output :-* 1.4.15.25 - - [30/Jan/2014:06:05:52 +0000] "GET /project/ajaxex.php?q=133 HTTP/1.1" 200 5323 "http://db11.app.com/project/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.102 Safari/537.36" 1.4.15.25 - - [30/Jan/2014:06:06:13 +0000] "GET /project/ajaxex.php?q=133 HTTP/1.1" 200 5323 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.102 Safari/537.36" No errors in error.log. Strange thing if i directly open below link in the browser, report is coming and i am able to see in the browser : *http:///db11.app.com/project/ajaxex.php?q=133 <http://db11.app.com/project/ajaxex.php?q=133>* It means my ajaxex.php is fine and no issues but dont understand why it is not working as expected after clicking on button.Please let me know if i am missing something. Thanks
