The Variable declared outside:
var total=0;
on success of AJAX{
total++;
alert(total);// gives value
}
alert(total)// gives zero value
Here I am getting the total value to be 0.
Your
ajaxrequest is likely asynchronous. This means that youralerthappens before the response has returned.Any code that relies on the response (like your alert) needs to be placed in your
onreadystatechangehandler.
