Is there any way to continue sending Ajax requests ( for example, in a polling application, where a request is sent whenever a response from the previous request is received, starting immediately on page load) when Javascript is turned on after it has been turned off by the user for some time?
And as for the value of variables, I have observed that the behavior is inconsistent: some browsers retain the value of the variables already set when Javascript is resumed, others don’t. So if I want to save all the values during a particular tab session, would it be a good idea to save all variables (there can be like thousands of them in a complex script!) as local variables (through local storage API, or jStorage, which works in IE6 and IE7 as well) that will auto destroy when the tab is closed?
If Ajax is depend on Javascript, It will not work when the turned off javascript support resumed in your browser without page reload by any mean.

I think it is not possible.
