如何通过使用jQuery Ajax调用来防止会话超时？

Question

I try to put following code into bottom of HTML page:

<script type="text/javascript">
var refreshTime = 300000;
    window.setInterval( function() {
        $.ajax({
            cache: false,
            type: "GET",
            url: "custom url",
            success: function(data) {
            }
        });
    }, refreshTime );
</script>

And I need when it exceed session time (30000 ms), then refresh with "custom url".

But as I try, the page wouldn't refresh or redirect with "custom url" after pass 30000 ms or 5 minutes.

Am I correct to do this?

Thanks

Answer 1

You can do the following in success function of ajax call:

setTimeout(function() {
    window.location.href = 'your-url-here';
}, 2000);

Answer 2

You have not implemented any reload function.

var refreshTime = 300000;
    window.setInterval( function() {
      location.reload();//reload 
// window.location.href = "custom url"; to redirect

 }, refreshTime );
