Programmatically close alert() in Javascript [duplicate]

Question

I'm trying to trigger an alert close once an event happens. Currently I get a popup when the internet cuts out (I want that). But once the connection is reestablished, I want the popup to automatically go away - not having to hit exit or OK.

I have this code:

 setInterval(function(){
if(navigator.onLine){
    ( ".selector" ).popup( "close" );
}else{
    window.alert("It seems you have lost connection to the internet. 
Please reconnect before continuing.");
}},2000);

Thanks

As far as I know you cannot close the javascript's alert(); by code. You can try to use alternative notification method like modal window or something (so then if user is back online you can simply use jQuery function to hide/remove the modal box).
