Ajax Question

How to escape a variable with a '.' in jquery/javascript?

Im using ajax to make a request. As part of the request I get an ID which is in an nested json. Like so:

{"id": 1,"point": ["2016-10-13 09:05:53",85],"id": 1,"point": ["2016-10-13 09:05:53",85]}

I then use a
loop to get all the data:

success: function(data) {
data.forEach(function(chartData) {
var series = window.chart1.series[0],

I want to use that ID in the json as a variable. So far I've tried:

var series =[0]

but I get an error:

Uncaught TypeError: Cannot read property '0' of undefined

When I input the ID directly:

var series = window.chart1.series[0],

it runs without any issue and if I console.log( I get the correct ID

How do I use the nested ID in the json as a variable?


You can use property accessing [] syntax.It will evaluate the expression and return to the [] the value.

var series = window['chart' +].series[0];
