Javascript for loading report using ajax:

         report.js is used for loading and downloading report using ajax.Js files are  located in /WebContent/js/  which also includes jquery-1.7.1.js.

         report.js has two functions:         

• generateReport(rptdesignDocName):This loades report in center div.
• downloadReport(format): Download current report in selected format.

     report.js code:
    

/**
 * This js contains two method 
 * 1)generateReport(reportName) : Requesting to load the report content in div.
 * 2)downloadReport(format): Downloading the current report in given format.
 */


//this will hold the currently loaded report name.
currentReportName="";
 /**
  * This method is responsible for loading the reports in the report div.
  * @param localReportName
  */
 function generateReport(reportName) {
 
  // here relative url is given if relative url is not working try giving full url
  var reporturl ="/BirtIntegration/loadReport?ReportName="+reportName+"&ReportFormat=html";
  
  $("#reportData").html("Loading...
");
  
        $('#reportData').load(reporturl ,function(response, status, xhr) {
         
          if (status == "error") {
      var msg = "Sorry but there was an error getting details ! ";
   $("#reportData").html(msg + xhr.status + " " + xhr.statusText);
    }
     });
        
        currentReportName=reportName;
 }
 
 /**
  * Download report function
  * 
  * @param format
  */
 function downloadReport(format){
  
  if(currentReportName==""){
   alert("Please Select the report.");
   return;
  }
  //here relative url is given if relative url is not working try giving full url
  var reporturl ="/BirtIntegration/loadReport?ReportName="+currentReportName+"&ReportFormat="+format;
  window.location.href = reporturl;
  
 }
