未捕获的TypeError：无法读取未定义的属性“时间戳”

Question

I am new to hightcharts, I have an error which I found it on chrome console. And the error is "Uncaught TypeError: Cannot read property 'timestamp' of undefined". Below is my code:

Javascript.JS:

if(selVal==str2[j]) {
    console.log("FOLDERNAME"+selVal);
    str3.push(str2[j+1]);
}

var json = str3[0];

**//This is for highcharts where I am trying to load myjson that is present in "var json"**
for (var k = 0; k < json.length; k++) {
    jsonArray.push({
    name: json[k].map.timestamp,**//Getting error over here**
    y:json[k].map.count
});

JSON FORMAT:

[{"map":{"timestamp":"2016-01-09 05:55:42.0","count":367}}]

Somebody please help me out in solving this. I almost tried everything.

Try this

 var json=[{"map":{"timestamp":"2016-01-09 05:55:42.0","count":367}}]; /***This is for highcharts where I am trying to load myjson that is present in "var json"**/ var jsonArray=[]; for (var k = 0; k < json.length; k++) { jsonArray.push({ name: json[k]["map"].timestamp, y:json[k]["map"].count }); } console.log(jsonArray)
