Auto refresh (Confirmed on version 4.7 Community)

[mrmangosir]

 Hi,

Thought I'd share how to create an auto share on Jasper CE 4.7. This may work on lower version, if they have the "refresh" functionality. One word of warning, this does not solve allowing only certain reports to refresh and not others, but its not too difficult.

So go to <jasperInstall>/webapps/jasperserver/web-inf/jsp/modules/viewreport/viewport.jsp.

Open the file and go to around line 80/81 and after <div id="viewerToolbar" class="toolbar"> add the below attached code. So your next task will be to have it adjustable. That is up to you how you want to be able to change that value.

Be warned that once that JSP has been saved and Tomcat restarted, *all* reports will not autorefresh.

Have fun.

Code:

<script type="text/javascript">    setInterval(function(){ document.getElementById('dataRefreshButton').click(); }, 10000); // every 5 seconds</script>

If anybody wants the full source to this, please post here and I will drop it in. After seeing all the questions about auto refresh in CE for years, might be worth the while to someone :)

Hello,

I used your idea and added the option to turn on and off, so you can turn the auto refresh only the reports you want.

 

This example was done on version 5.1.

 

To add the button auto refresh change the following files:

 

in file jasperserverscriptsreport.view.runtime.js change the line 41 of

$(Report.DATA_REFRESH_BUTTON).observe( 'mouseup', function() {

 

to

 

$(Report.DATA_REFRESH_BUTTON).observe( 'click', function() {

 

in file jasperserverWEB-INFjspmodulesviewReportViewReport.jsp

on line 63 after the imports scripts add the following script

 

<script >

                       var auto

                       function iniciar()

                       {

                            auto = self.setInterval( function(){clicar()}, 300000);//5 minutos

                            document.getElementById( 'iniciar').style.display = "none";

                            document.getElementById( 'parar').style.display = "";

                       }

                       function parar()

                       {

                          auto = window.clearInterval(auto);

                          document.getElementById( 'iniciar').style.display = "" ;

                            document.getElementById( 'parar').style.display = "none";

                       }

                       

                       function clicar()

                       {

                         document.getElementById( 'dataRefreshButton').click();

                       }

                      

                     

  </script>

 

And in line 158 (before pasting the script) change the code

 

<c:if test= "${param.decorate != "no"}">

    <ul class="list buttonSet">

        <li class= "leaf"><button id="back" class= "button capsule text up" ><span class="wrap" ><spring:message code= "button.back"/><span class="icon" ></span></ span></button ></li>

    </ul >

</c:if>

 

To (just added the two buttons)

 

<c:if test= "${param.decorate != "no"}">

    <ul class="list buttonSet">

        <li class= "leaf"><button id="back" class= "button capsule text up" ><span class="wrap" ><spring:message code= "button.back"/><span class="icon" ></span></ span></button ></li>

        <li class= "leaf"><button id="iniciar" class= "button capsule text up" onclick="iniciar();" title ="Iniciar a atualização automatica a cada 5 min"/><span class="wrap" >Auto </span></ button></li >

               <li class= "leaf"><button id="parar" class= "button capsule text up" style="display :none" onclick="parar();" title= "Parar atualização automatica"/>< span class ="wrap"> Stop</ span></button ></li>

    </ul >

</c:if>

 

Be happy :D

In new versions edit the file ~/jasperserver/optimized-scripts/report.viewer.page.js instead of JasperServer file jasperserverscriptsreport.view.runtime.js For this look inside the file by Report.DATA_REFRESH_BUTTON to locate what should be changed as mentioned in answer (mouseup -> click)

[pokornyjan]

Did you try It with version 6.3?

I added button but refresh refresh does not work.

Thank you for help

the problem is that that the code is using 'mouseup' event and not 'click'.

instead of the above code, you  can use:

<script>    function triggerEvent(el, type){     if ('createEvent' in document) {        // modern browsers, IE9+        var e = document.createEvent('HTMLEvents');        e.initEvent(type, false, true);        el.dispatchEvent(e);     } else {        // IE 8        var e = document.createEventObject();        e.eventType = type;        el.fireEvent('on'+e.eventType, e);     }    }     self.setInterval(function(){     var el = document.getElementById("dataRefreshButton");     triggerEvent(el,'mouseup');    },10000);    </script>[/code]

Hi omer.etrog,
your code is working. (works permanently and over all reports).
How do I set the code for only one report?

Thank you for help
