Dynamic variable in javascript push function

Question

I'm using push function in javascript.

var chartData = [];
for(var i=0; i<3; i++) {

    chartData.push({

        date: new Date(year_s,mon_s,date_s,hr_s,min_s,sec_s),
        visits: chartData1[selection[i]][j].value,
        customBullet: show_annotations,
        balloonTextField: "testtesttest"
    });

}

I need to pass a dynamic variable like visits_1, visits_2, etc,. in place of visits variable in the above code. I have tried visits+"_"+i. But it is not working. Please help me to achieve this. Thanks in advance.

Note that there is no JSON in the code shown (JS objects and JSON are different things). — nnnnnn

And this isn't really a problem of variable but of property. — Denys Séguret

You have to make it in two steps :

var chartData = [];
for(var i=0; i<3; i++) {
   // 1. create the object
   var d =  { 
      date: new Date(year_s,mon_s,date_s,hr_s,min_s,sec_s),
      customBullet: show_annotations,
      balloonTextField: "testtesttest"
   };
   // 2. then assign the visits_i property
   d['visits_'+i] = chartData1[selection[i]][j].value; 
   chartData.push(d);
}
