export to pdf option doesn't seem to run scripts in Custom HTML Controls added to an NPM Page

Daniel_Miller

I have the following code in a Solarwind's custom html control that produces Charts on an NPM Page.

Code:

<img name="ChartResponse" src="" />

<Script>
  var objElementChart = document.getElementById('ChartResponse');
  var strChartName ="AvgRT";
  var strResourceID="14";
  var strWidth="640";
  var strHeight="0";
  var iTotal = 10;
  var objServers = new Array();

  objServers[0]="471";
  objServers[1]="472";
  objServers[2]="473";
  objServers[3]="475";
  objServers[4]="476";
  objServers[5]="477";
  objServers[6]="478";
  objServers[7]="479";
  objServers[8]="480";
  objServers[9]="481";
  
  var strPrefix="N";
  var query = location.href.substring((location.href.indexOf('?')+1), location.href.length);
  var objParentElement = document.getElementById(objElementChart.parentNode.id);
  var objImageElement;
  var Index = 0;

  if(location.href.indexOf('?') < 0) query = '';

  querysplit = query.split('&');
  query = new Array();

  for(var i = 0; i < querysplit.length; i++)
  {
    var namevalue = querysplit.split('=');
    namevalue[1] = namevalue[1].replace(/\+/g, ' ');
    query[namevalue[0]] = unescape(namevalue[1]);
  }

  var strStartPeriod=query['StartPeriod'];
  var strEndPeriod=query['EndPeriod'];

  if(strStartPeriod == "")
  {
    strStartPeriod=query['startperiod'];
    strEndPeriod=query['endperiod'];
  }

  if(typeof strStartPeriod == 'undefined')
  {
    var strStartPeriod="12:00 AM";
    var strEndPeriod="11:59 PM";
  }

  objElementChart.style.visibility="hidden";
  var strSrcURL = "";

  for(Index = 0; Index < iTotal; Index++)
  {
    objImageElement = document.createElement("image");

    strSrcURL = "/Orion/Netperfmon/Chart.aspx?SubsetColor=&RYSubsetColor=&ChartName=" + strChartName + "&Title=&SubTitle=&SubTitle2=&Width=" + strWidth + "&Height=" + strHeight + "&SampleSize=5M&ShowTrend=True&FontSize=1&NetObject=" + strPrefix + ":" + objServers[Index] + "&ResourceID=" + strResourceID + "&NetObjectPrefix=" + strPrefix + "&Period=" + strStartPeriod + "~" + strEndPeriod + "&Rows=&CustomPollerID=&PlotStyle=&ReturnTo=";
 
    objImageElement.Name =strChartName + Index;
    objImageElement.src = strSrcURL;
    objParentElement.appendChild(objImageElement);
  }
</Script>

The Code produces charts for the requested nodes on a single page.  But When I hit the export to pdf function, the PDF produced contains only an "X" placement holder in the custom html box for each of the controls.  Any Ideas why?
