I am able to generate the chart after removing $(document).ready() and
using the technique that you pointed out but without using ready function
my $.ajax() does not work upon selecting a value from drop down which I
need for dynamic data generation. So i need to have these two techniques
collaborating. Any way out?
The script I am using right now:
google.load('visualization', '1', {
packages: ['corechart']
});
function drawBasic(d) {
var data = new google.visualization.DataTable(d);
var options = {
title: 'Sample Data',
hAxis: {
title: 'Name'
},
vAxis: {
title: 'Count'
},
width: 400,
height: 240
};
var chart = new google.visualization.ColumnChart(document.
getElementById('chart_div'));
chart.draw(data, options);
}
$("#dd").change(function(){
$.ajax({
url : "Serv",
data: {dd1:$(this).val()};
dataType: 'json',
contentType: 'application/json',
success : function(result) {
alert(result);
google.setOnLoadCallback(drawBasic(result));
},
complete: function(){
// whatever..
}
});
});
where 'dd' is the id of drop down after which I am sending its value to
servlet for further processing but this doesnt work without
document.ready().
