multiple drop downs in one page

[Yann]

I needed to have multiple lists on the same page, I changed the code a bit to use a dataSrc attribute.
The code will now read the attribute and reset the list. Seems to be working fine.
function processSmartInput(inputBox) {
    if ( lastCollectionName != null && inputBox.getAttribute( "dataSrc" ) != null  && inputBox.getAttribute( "dataSrc" ).length > 0 && lastCollectionName != inputBox.getAttribute( "dataSrc" ) ) {
        updateCollection( eval( inputBox.getAttribute( "dataSrc" ) ) );
    }
    else if ( lastCollectionName == null && inputBox.getAttribute( "dataSrc" ) != null && inputBox.getAttribute( "dataSrc" ).length > 0  ) {
        updateCollection( eval( inputBox.getAttribute( "dataSrc" ) ) );
    }
    lastCollectionName = inputBox.getAttribute( "dataSrc" );

function updateCollection( newCollection ) {
    collection = newCollection;   
    collectionIndex = new Array();
}
is basically all I had to do.

Thanks for the code in the first place.

NICE!

Another way to do this is to structure your data sources like this:

var my_data = { addresses: [ ... ],
                searches: [ .... ],
};

Then put the associated key in the "dataSrc" attribute, so the patch would just look like:

function processSmartInput(inputBox) {
collection = my_data[inputBox.getAttribute("dataSrc");
...

This might save a few CPU cycles because you're not re-creating the whole data object each time the input box switches, just reassigning a reference. And you're not calling "eval". (But I'm no JavaScript expert, so take all this with a quantity of salt about the size of that mountain of cocaine that Al Pacino buries his face in at the end of Scarface.)

implemented Evan Miller's Suggestion:
it required a few other changes:

in wick_sample.html changed collection.length to new TotalCollectionLength

<!-- WICK STEP 3: INSERT WICK LOGIC -->
<script>
TotalCollectionLength=0
for (var dataSrc in my_data)
{
TotalCollectionLength += my_data[dataSrc].length
}
document.getElementById("wickStatus").innerHTML = '<a target="_blank" href="./sample_data.js">Loaded <b>' + TotalCollectionLength + '</b> Sample Addresses</a>';
</script>
---------------------------------------
in wick.js:
Changed runMatchingLogic to include dataSrc as 3rd calling argument:

function runMatchingLogic(userInput, standalone, dataSrc) {
...
        collection = my_data[dataSrc]; //addded
        pointerToCollectionToUse = collection;
---------------------------------------
in wick.js:
fixed calls to runMatchingLogic with 3rd Arg:
in function smartInputData
...
runMatchingLogic(userInput,false,siw.inputBox.getAttribute("dataSrc"));

in function activateCurrentSmartInputMatch:
...
runMatchingLogic(addedValue, true, siw.inputBox.getAttribute("dataSRC"));

comment out or fix comma replacement:
//note: instruct users to the fact that no commas should be present in entries.
//it would make things insanely messy.
//this is why i'm filtering commas here:
//for (x=0;x<collection.length;x++) {
//collection[x] = collection[x].replace(/\,/gi,'');
//}//

I commented it  out but you could use something similar to to the TotalCollectionLength to fix ... like (untested):

for (var dataSrc in my_data)
{
for (x=0;x<my_data[dataSrc].length;x++) {
my_data[dataSrc][x] = my_data[dataSrc][x].replace(/\,/gi,'');
}
}

For what it's worth:
I typoed DataSRC  above:

>in function activateCurrentSmartInputMatch:
>...
>runMatchingLogic(addedValue, true, siw.inputBox.getAttribute("dataSRC"));

It should be:
in function activateCurrentSmartInputMatch:
...
runMatchingLogic(addedValue, true, siw.inputBox.getAttribute("dataSrc"));

still worked though.
