Looking to extract specific values from a JavaScript object? Read on.
<script>
var market = "arizona";
var marketNumbers = {
"arizona" : "800 555-1234|866 452-8569",
"florida" : "800 555-4567|866 452-9999"
};
for (market in marketNumbers) {
var tmp = marketNumbers[market].split('|');
alert(tmp(0));
};
</script>

<script>
var market = "arizona";
var marketNumbers = {
"arizona" : "800 555-1234|866 452-8569",
"florida" : "800 555-4567|866 452-9999"
};
var tmp = marketNumbers[market].split('|');
alert('Found '+tmp.length+' items. Your first item is '+tmp[0]);
</script>
Properly accessing the arrays...

var countryCodes = {
"canada" : "800 123-4567|866 789-0123",
"mexico" : "800 555-9876|866 444-3333"
};
for (var code in countryCodes) {
var numbers = countryCodes[code].split('|');
for (var j = 0; j < numbers.length; j++) {
alert('Phone Code [' + code + ']: ' + numbers[j]);
}
};
