Hi,
I am new to Google charts and facing a strange issue on using it.
Problem:
I have used an ajax call to retrieve data for Organizational Chart. *Problem
is that I am having some important values stored in Session which are not
accessible after this ajax call* i.e. the reference to those parameters is
becoming null.
Please see the below code which I am using to draw my chart. Kindly help me
if someone has idea that why my session is clearing after this Code
Execution!
google.charts.load('current', { packages: ["orgchart"] });
google.charts.setOnLoadCallback(drawChartApplicationSpecific);
function drawChartApplicationSpecific() {
var pagePath = window.location.pathname;
$.ajax({
type: "POST",
url: pagePath + "/GetOrgDataListObject",
data: {},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccess_getOrgData,
error: OnErrorCall_getOrgData
});
function OnSuccess_getOrgData(repo) {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Name');
data.addColumn('string', 'Manager');
data.addColumn('string', 'ToolTip');
var response = repo.d;
for (var i = 0; i < response.length; i++) {
var row = new Array();
var empName = response[i].Employee;
var mgrName = response[i].Manager;
var empID = response[i].empID;
var mgrID = response[i].mgrID;
var designation = response[i].designation;
var image = response[i].imagePath;
data.addRows([[{
v: empID,
f: empName + "<div style='color:red;
font-style:italic'>" + designation + "</div><br/><img
style='height:50px;width:50px;' src=" + image + " /><br/>"
}, {
v: mgrID,
f: mgrName
}, designation]]);
}
var chart = new
google.visualization.OrgChart(document.getElementById('chart_div'));
chart.draw(data, { allowHtml: true, size: 'small' });
}
function OnErrorCall_getOrgData() {
alert("Whoops something went wrong :( ");
}
}
