jquery .each wwith a dynamic name / variable

Question

I have the following syntax:

 $.each(result, function(key, value){
         alert(value.first_name);
    });

first_name is obviously a value in the array.

what I want/need to do is something like this:

$.each(result, function(key, value){
var column='first_name';
             alert(value.column);
        });

I want to alert the value in the array that comes from a variable. this obviously fails as it sees column as an array key rather that a variable.

is this possible?

alternatively something like alert(value[2]) will work as well

Thanks,

Answer 1

Use value[column] instead of value.column

var value = {
    first_name: 'John'
  },
  column = 'first_name';

alert(value[column]);
