How to automatically reload a page after a given p

2楼-- · 2019-01-02 19:54

<script type="text/javascript">
  var timeout = setTimeout("location.reload(true);",600000);
  function resetTimeout() {
    clearTimeout(timeout);
    timeout = setTimeout("location.reload(true);",600000);
  }
</script>

Above will refresh the page every 10 minutes unless resetTimeout() is called. For example:

<a href="javascript:;" onclick="resetTimeout();">clicky</a>

Based on the accepted answer of arturnt. This is a slightly optimized version, but does essentially the same thing:

var time = new Date().getTime();
$(document.body).bind("mousemove keypress", function () {
    time = new Date().getTime();
});

setInterval(function() {
    if (new Date().getTime() - time >= 60000) {
        window.location.reload(true);
    }
}, 1000);

Only difference is that this version uses setInterval instead of setTimeout, which makes the code more compact.

Yes dear,then you have to use Ajax technology. to changes contents of particular html tag:

 <html>
    <head>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <title>Ajax Page</title>
        <script>
        setInterval(function () { autoloadpage(); }, 30000); // it will call the function autoload() after each 30 seconds. 
        function autoloadpage() {
            $.ajax({
                url: "URL of the destination page",
                type: "POST",
                success: function(data) {
                    $("div#wrapper").html(data); // here the wrapper is main div
                }
            });
        }
        </script>
    </head>
    <body>
    <div id="wrapper">
    contents will be changed automatically. 
    </div>
 </body>
 </html>

I would consider activity to be whether or not the user is focused on the window. For example, when you click from one window to another (e.g. Google Chrome to iTunes, or Tab 1 to Tab 2 within an internet browser), the webpage can send a callback saying "Im out of focus!" or "Im in focus!". One could use jQuery to harness this possible lack of activity to do whatever they wanted. If I were in your position, I would use the following code to check for focus every 5 seconds, etc and reload if no focus.

var window_focus;
$(window).focus(function() {
    window_focus = true;
}).blur(function() {
    window_focus = false;
});
function checkReload(){
    if(!window_focus){
        location.reload();  // if not focused, reload
    }
}
setInterval(checkReload, 5000);  // check if not focused, every 5 seconds

This can be accomplished without javascript, with this metatag:

<meta http-equiv="refresh" content="5" >

where content ="5" are the seconds that the page will wait until refreshed.

But you said only if there was no activity, what kind for activity would that be?

And finally the most simple solution:

With alert confirmation:

<script type="text/javascript">
    // Set timeout variables.
    var timoutWarning = 3000; // Display warning in 1Mins.
    var timoutNow = 4000; // Timeout in 2 mins.

    var warningTimer;
    var timeoutTimer;

    // Start timers.
    function StartTimers() {
        warningTimer = setTimeout("IdleWarning()", timoutWarning);
        timeoutTimer = setTimeout("IdleTimeout()", timoutNow);
    }

    // Reset timers.
    function ResetTimers() {
        clearTimeout(warningTimer);
        clearTimeout(timeoutTimer);
        StartTimers();
        $("#timeout").dialog('close');
    }

    // Show idle timeout warning dialog.
    function IdleWarning() {
        var answer = confirm("Session About To Timeout\n\n       You will be automatically logged out.\n       Confirm to remain logged in.")
            if (answer){

                ResetTimers();
            }
            else{
                IdleTimeout();
            }
    }       

    // Logout the user and auto reload or use this window.open('http://www.YourPageAdress.com', '_self'); to auto load a page.
    function IdleTimeout() {
        window.open(self.location,'_top');
    }
</script>

Without alert confirmation:

<script type="text/javascript">
    // Set timeout variables.
    var timoutWarning = 3000; // Display warning in 1Mins.
    var timoutNow = 4000; // Timeout in 2 mins.

    var warningTimer;
    var timeoutTimer;

    // Start timers.
    function StartTimers() {
        warningTimer = setTimeout(timoutWarning);
        timeoutTimer = setTimeout("IdleTimeout()", timoutNow);
    }

    // Reset timers.
    function ResetTimers() {
        clearTimeout(warningTimer);
        clearTimeout(timeoutTimer);
        StartTimers();
        $("#timeout").dialog('close');
    }

    // Logout the user and auto reload or use this window.open('http://www.YourPageAdress.com', '_self'); to auto load a page.
    function IdleTimeout() {
        window.open(self.location,'_top');
    }
</script>

Body code is the SAME for both solutions

<body onload="StartTimers();" onmousemove="ResetTimers();" onKeyPress="ResetTimers();">
