I have an array and I want to sort by the number field not the name.

var showIt = [

  [nuCycleDate,19561100],

  [ndCycleDate,19460700],

  [neCycleDate,0],

  [nlCycleDate,0]

];

Thanks

You can provide sort with a comparison function.

showIt.sort(function(a, b) {

    return a[1] - b[1];

});

a and b are items from your array. sort expects a return value that is greater than zero, equal to zero, or less than zero. The first indicates a comes before b, zero means they are equal, and the last option means b first.
