How to auto-refresh a report? [message #518770]

I have a table-based report and I wish the HTML version's page to automatically refresh every X seconds. How can I do this?

i tried putting the following in a text element at the top of my report but it doesn't work, I think I have to put it someplace else or use Javascript somewhere:

<meta http-equiv="refresh" content="60" >

I am using BIRT 2.2.1.

Thanks!

Lawrence,

I do not remember if this works in 2.2.1 but it works in the latest
versions of BIRT. Add a text element set the type to html and enter a
value similar to the following.

<form name="input" onSubmit="return reloadPage();">

<script type="text/javascript">

function reloadPage() {
//alert("Reload time");
var temp = new String(location.href);
var targetURL = new String();

if(temp.indexOf("__overwrite=") != -1 ){
targetURL = temp.substring(0, temp.indexOf("&__overwrite") -1);
}else{
targetURL = temp;
}

targetURL += "&__overwrite=true";

//alert( targetURL );
location.replace(targetURL);

return false;
}

timer=setTimeout('reloadPage()', 5000);
</script>

</form>

In case it's useful to anyone, I am posing the actual, shortened version I used which works ok in 2.2.1. Basically,I removed the "overwrite" section from Jason's example above -- and it seems to work fine. Is there any specific reason for the overwrite section?

<form name="input" onSubmit="return reloadPage();">

<script type="text/javascript">

function reloadPage() {
var targetURL = new String(location.href);
location.replace(targetURL);
return false;
}

timer=setTimeout('reloadPage()', 60000);
</script>

</form>

The overwrite section causes the report to re-execute producing an
updated rptdocument. Without it changes in source data may not be
picked up.

Jason,
Ok, I get it, sorry for butchering your code. I put it back as you originally stated, and remembered why I took out the overwrite section: for a report that has a required parameter, it re-prompts me for that parameter(s). So now I can't figure out how to refresh the report with the same parameter(s) as it was originally run with, while keeping the "overwrite" parameter section.

Are you putting the parameter values in the url?

Yes I am putting parameters in the URL. Also, I need this to work both for some reports which do have parameters in the URL, and also for some other reports which have no parameters. Maybe that means 2 different scripts I think.

Thank you again for any further advice.

Can you post the script/report you are using? If the parameters are in
the URL the parameter box should not be prompting.

Hi Jason

I used the code provided by in my report with refresh interval as 30sec,

Every 30 sec page is getting refreshed but the data updated at back end is not reflecting.

I have used complete javascript code with overwrite option.

Also once i execute the report from BIRT tool it will open the report with dateTime at the left end of window and this dateTime value also not getting updated with page refresh.

I am using Birt

Actuate BIRT Designer Professional
Version: 4.4.0

Thank you
Tejas
