This question already has an answer here:

I have a string containing following data:

6,11,32,110,235,369,640,1005,1436,2063,3057,4618,6444,9822,15468,20434,24126,27387,29459,31056,31982,32040,31233,29224,27342,26662,26956,27912,28999,28965,27826,25579,25722,24826,24605,24304,23464,23708,24099,24357,24237,24401,24344,23586,22380,21004,17287,14747,13076,12555,12144,11009,10950,10871,10824,10577,10527,10475,10421,10358,10295,10104

basically i am reading this string from a file, i want to pass it on to the data of a series in highchart. when i do data:(above mentioned string), no data gets displayed, maybe because it is a string (even though everything gets declared as var). but when i declare an array of data myself like

var series = [6,11,32,110,235,369,640,1005,1436,2063,3057,4618,6444,9822,15468,20434,24126,27387,29459,31056,31982,32040,31233,29224,27342,26662,26956,27912,28999,28965,27826,25579,25722,24826,24605,24304,23464,23708,24099,24357,24237,24401,24344,23586,22380,21004,17287,14747,13076,12555,12144,11009,10950,10871,10824,10577,10527,10475,10421,10358,10295,10104];

It displays the data on to the chart. So kindly tell me how to convert the string i'm reading from file into the array of data i declared.

Your question would look better if you put your current file reading script... – vogomatix Mar 12 '14 at 16:36

If Highcharts only accepts arrays of integers, you can split the string into an array and then use map to cast the strings either into integers or floating point numbers:

var arr = str.split(',').map(function (el) {
  return parseInt(el, 10);
});

Fiddle

Or just str.split(',').map(Number) – xdazz Mar 12 '14 at 16:47

Use .split method:

> "6,11,32,110,235,369".split(',')
  ["6", "11", "32", "110", "235", "369"]

And if you want them be a number:

> "6,11,32,110,235,369".split(',').map(Number)
  [6, 11, 32, 110, 235, 369]

Let's take a look at the following example. You will have a better understanding of the whole process of converting string into array. You can copy and paste the code to see if that works.

 <!DOCTYPE html>
 <html>
 <body>

<p id="demo">Click the button to display the array values after the split.</p>

<button onclick="myFunction()">Try it</button>
<script>
function myFunction()
    {
      var strValue = "How are you doing today?";
     var StrToArray = str.split("");
     document.getElementById("demo").innerHTML=res;
}
</script>

</body>
</html>

Equal the string to a variable, and then use the split() method.

string.split(',');

The array has to be numbers, not strings. – Andy Mar 12 '14 at 16:50
