Javascript scope variable..?
500 <script type="text/javascript">
501 google.load("visualization", "1",
{packages:["table"]});
502 google.setOnLoadCallback(drawTable);
503 function drawTable() {
504 var data = new
google.visualization.DataTable();
505 data.addColumn('string', 'Id');
506 data.addColumn('string', 'PI');
507 data.addColumn('string', 'Cruise
Info');
508 data.addColumn('string', 'Date and
Time');
509 data.addColumn('string', 'Latitude');
510 data.addColumn('string', 'Longitude');
511 data.addColumn('string', 'Depth');
512 data.addColumn('string', 'Name');
513 data.addColumn('string', 'Value');
514 data.addRows(1);
515
516 GDownloadUrl("../output/search/
results.xml", function(data) {
517 xml = GXml.parse(data);
518 dataId =
xml.documentElement.getElementsByTagName("data_id");
519 // alert(dataId[0].childNodes
[0].nodeValue);
520 id = dataId[0].childNodes
[0].nodeValue;
521 // alert(id);
522 // for (var i = 0; i <
dataId.length; i++) {
523 // var id = new Integer(parseInt
(dataId[i]));
524 // alert(id);
525 // }
526 data.setCell(0, 0,
"id");
527 });
528 data.setCell(0, 0, "id");
529 var table = new
google.visualization.Table(document.getElementById('table_div'));
530 table.draw(data, {showRowNumber:
true});
531 }
532
533 </script>
Line 526 does not work.
Line 528 does.
This leads me to believe I cannot run setCell inside.. the called to
GDownloadUrl. However, this brings up the issue of variable scoping.
For example, I am not able to do "alert(id)" outside of the call to
GDownloadUrl either. Even if I declare id as a global var.
