Question

So..

I am passing data to a function that handles strings and numbers differently.

I would LIKE to be able to pass an array of values and detect what the types of each value is.

row[0] = 23;
row[1] = "this is a string... look at it be a string!";
row[2] = true;

$.each(row, function(){
  alert(typeof(this));
  //alerts object
});

Is it possible to detect the “actual” datatypes in a given row?

Answer 1

Try

var row = [ 23, "this is a string", true ];

$.each(row, function (index,item) {
    alert(typeof(item));
});

// Alerts "number", "string", "boolean"

Whenever possible I try to avoid using “this” in callbacks and using explicit arguments is usually clearer and more predictable.
