Sorting JS Array

I have a large array, returned from a callserver to populate a select list,
something like Option (value, label, 0,0) 75 deep.

Can I easily sort on one column of this array ? Or do I need to sort it myself and keep the various columns in sync ?

It is currently sorted on value, which is how the data is read, but the users want it sorted on the label.

Tips/Pointers/RTFMs appreciated

You can certainly play with the JavaScript sort Method. If I were you I would probably sort on the callServer side, it's much more flexible in Perl

Those examples show a one column array, this is a 4 column array & I needot keep the rows in sync.

My thought is, if I need to put the value in a hash (by label) and then sort the label, finally determine selected or not. I would certainly do that in Perl. My other option is to ignore the request. Smiley Very Happy

What do you mean by "4-column Array"? Using optional sort Function you can sort an array of Objects (like an Array of Option objects for example).
In this case you yourself decide(code) what is the "lesser" one. The slang is that you "Set Object Metrics". It works pretty much like
Perl's USERSUB in sort USERSUB LIST syntax

I build an array like this:

newOptions = new Option(DCRLabels, DCRValues, false, false)

I cannot sort one without making certain that the other columns are correct.

So if I cannot sort this array on Column 1 (DCRLabels), then I need to change how I build the list.

Quick and dirty - something like the following. Note that I did not test it

//Declare
var newOptions = new Array; 

// Populate it...
for (var i=0; i<DCRLabels.length; i++) {
   newOptions = new Option(DCRLabels, DCRValues, false, false);
}

// Sort Populated
newOptions.sort(byText); // Note - what you've called "Label" is Option's Class text Attribute
// OR newOptions.sort(byValue);

function byText(a, b) {
   return a.text > b.text;
}
function byValue(a, b) {
   return a.value > b.value;
}
