How to get the dataset value in table using Jquery

Question

I was trying to get the label and data value from the following

var barChartData = {
  labels: Months,
  datasets: [{
    label: 'Dataset 1',
    backgroundColor: "#09a",
    data: [5, 10, 15, 20, 25, 30, 35]
  }]
};

I tried using alert(JSON.stringify(barChartData.datasets.data)); but I got output as undefined. Please help me to find out this .

Answer 1

Like Sachin K wrote in the comment.

You forget that datasets is an array containing an object.

Therefor you need

alert(JSON.stringify(barChartData.datasets[0].data))

With the [0] you specify that you want the value from the first element in the array (array's are zero based)

Answer 2

Try this approach..

 var barChartData = { labels: 'Months', datasets: [{ label: 'Dataset 1', backgroundColor: "#09a", data: [5, 10, 15, 20, 25, 30, 35] }] }; //For multiple dataset var data = []; label = []; barChartData.datasets.map(function(dt) { data.push(dt.data); label.push(dt.label); }) //Single datasets var data1 = barChartData.datasets[0].data; var label1 = barChartData.datasets[0].label; console.log(data, label, data1, label1);
