Script to avoid session timeout

[eddparsons]

Hi,

Is there a script I can use to regularly refresh a form thus avoiding a session timeout?

I found http://www.webdevbros.net/2006/12/14/ke ... avascript/ while googling and have tried adding the script to the ready event of the page under HTML properties but I can't get it to work.

Regards,
Edd

Hi,

Ik think the problem with this script is that in the 'refresh', there is no interaction with the Ebaseserver, so it's session is not updated.

Maybe you can call a dummy ebase function, or update a dummy field value. Then the server 'knows' that the form is still being used.

Something like this (not tested!):

Code: Select all

    function keepMeAlive() {
       var date = new Date();
       $eb.setFieldValue('DUMMY_FIELD', date, false);
    }
    window.setInterval(keepMeAlive, 100000);

In the form you set 'Client accessibility' property of the DUMMY_FIELD to 'Read/write'.

Hi Edd,
I have a button in a form that is hidden by JQuery, this has a script to simply log a statement (ie interact with the server). Then within the form html++ the following simply clicks the button every 10 minutes to keep the form alive.

Code: Select all

<script>  
$&#40;document&#41;.ready&#40;function&#40;&#41; &#123;
	setTimeout&#40;RunEvent,60000&#41;;
&#125;&#41;;

function RunEvent&#40;&#41; &#123;
   setTimeout&#40;RunEvent,600000&#41;;
	$&#40;"#TriggerButton"&#41;.trigger&#40;'click'&#41;;
&#125;
</script>
