I want to redirect to another page if a condition in javascript is true

I am developing a desktop app with Adobe AIR. I want to redirect to another page if internet connection is present, and do nothing if internet connection is not present.

Following is the code I am using for detecting internet connection. The following code displays "Please wait" if internet connection is present, and "Internet connection is unavailable" if internet is not connected.

`

<!doctype html>
<html>
<head>
    <script>
        function CheckOnlineStatus(msg) {
            var status = document.getElementById("status");
            var condition = navigator.onLine ? "Please wait" : "Internet connection is unavailable"; 
            var state = document.getElementById("state");
            state.innerHTML = condition;
        }

        function Pageloaded() {
           CheckOnlineStatus("load");
           document.body.addEventListener("offline", function () {
           CheckOnlineStatus("offline")
           }, false);
           document.body.addEventListener("online", function () {
           CheckOnlineStatus("online")
           }, false);
        }

    </script>
    <style>
        ...</style>
</head>
<body onload="Pageloaded()">
    <div id="status">
        <p id="state">
        </p>
    </div>
</body>
</html>`

Please suggest required additions or changes to redirect to "http://example.com" if navigator.onLine is true.

Solution 
  • if(navigator.onLine){
     window.location.href = "http://example.com";
}

    window.location is an object which exists as a property of window. href is a property of window.location which indicates the URL of your current page. You can redirect by assigning a URL to window.location.href.
