I have a array called tableData, which has two elements inside it tableData[0] and tableData[1]. So I am accessing one of the column of tableData[1] like so

tableData[1][0].id , tableData[1][1].foo , tableData[1][2].bar and the list goes on.

But I don't want to hardcode it. The names id,foo,bar is in the tableData[0] that is actually all the heading of the columns and The tableData[1] has it's corresponding values. so I want to so something like this

tableData[1][0].tableData[0][1] But doing this for some weird reason say error Cannot read property '0' of undefined and I also tried this

var a = tableData[0][1].COLUMN_NAME
tableData[1][0].+a

But this is not possible? It says syntax error! How can I access the varible without hard-coding it.

Could you post the contents of the tableData variable so we can see it's formatting? – mikeg542 Apr 13 '17 at 18:27

I think you want `tableData[1][0][tableData[0][1]]`. – user94559 Apr 13 '17 at 18:28
use `[]` object notation – charlietfl Apr 13 '17 at 18:28
check out the content of the array @mikeg542 – Rehan Apr 13 '17 at 18:33

With that content, then e.g. `tableData[1][0][tableData[0][1].COLUMN_NAME]`. – user94559 Apr 13 '17 at 18:34
Thanks everyone. Solved it. Can someone please explain without `.` it works and `.` gives me error? @charlietfl @smarx – Rehan Apr 13 '17 at 18:36

The question this has been marked a duplicate of is probably the right place to learn more. – user94559 Apr 13 '17 at 18:40
