how can I make my json array sort function case insensitive?

Question

I have the following fiddle that is my attempt at

• taking a json array
• sort the array by the displayname value
• add the sorted array to the DOM as

Answer 1

Use the function toLowerCase() and convert to string with + ""

myArray.jsonData.sort(function(a, b) {
   var comp = ((a[prop]+"").toLowerCase() >
               (b[prop]+"").toLowerCase()) ? 1 : -1 ;
   return asc ? comp : -comp;
});

Answer 2

If you are always sorting strings, you can use:

function(a,b){
   return a.toLowerCase() > b.toLowerCase();
}

which in your example would be:

myArray.jsonData.sort(function(a,b){
    var result, 
        av=a[prop].toLowerCase(), 
        bv=b[prop].toLowerCase();
    return asc ? av > bv : av < bv;
}
