JS Stop Ajax Timer Control __JS

In C # to stop or start the timer is too easy, but this will have to return to the server and refresh the page, even if you use Ajax UpdatePanel, or return, some client operations or do white, such as the display of a layer and disappeared. Using JavaScript can be used to solve the problem. Fortunately, there are two proprietary methods available in AJAX Timer _starttimer () and _stoptimer () the following two client example codes show you how to use both methods:
function Starttimer ()
{var timer = $find ("<%=ajaxTimer.ClientID%>")
Timer._starttimer ();
}
function Stoptimer ()
{
var timer = $find ("<%=ajaxTimer.ClientID%>")
Timer._stoptimer ();
}
