How to extract value from an array of array

Question

I have an array of array stored. I need to extract the particular value from this arrays.

e.g allarray contain the list of arrays allarray= [Array[3],Array[3],Array[3]]

Answer 1

If I understand you correctly, your array looks like this

var allarray = [["a1","b1","c1"],["a2","b2","c2"],["a3","b3","c3"]];

To get c1, c2, and c3 you could just do this

 var c1 = allarray[0][2], c2 = allarray[1][2], c3 = allarray[2][2];

or you could do a loop to put all of the cs in a single array of its own

var cs = [];
for(var i = 0; i < allarray.length; i++) {
  cs.push(allarray[i][2]);
}
