Today I find myself not much, about judging whether the Internet

Have some problems today, so here's a summary and save it.

The first one: about how to use JS to determine whether the network is connected

This method is determined by using the online property of the navigator new feature of HTML5, which makes it easy to determine whether the line is judged (true: online; false: Offline);

Simply determine if the network is not connected

if (window.navigator.online==true) {

Alert ("linked");

}else{

Alert ("Not Connected");

}

About the Window.navigator.onLine event

The OnLine property is a read-only Boolean value that declares whether the system is in offline mode.

Note: In IE 4+, users can select the status of working offline in the browser. When the offline work is selected, the system goes offline and the content is read from the cache
