I've been searching and searching and haven't found a solution...even though, likely, it's simple. How do I create something that will give me this:
myArray['key1'].FirstName = "First1";
myArray['key1'].LastName = "Last1";
myArray['key2'].FirstName = "First2";
myArray['key2'].LastName = "Last2";
myArray['key3'].FirstName = "First3";
myArray['key3'].LastName = "Last3";
And then say something like, alert(myArray['key2'].FirstName);
And will I be able to iterate through it like:
for(i=0; i < myArray.length; i++){
//do whatever
}
Thanks in advance!

You can init an object something like that:
{
"key1": {FirstName: "first1", LastName: "last1"}
"key2": {FirstName: "first2", LastName: "last2"}
"key3": {FirstName: "first3", LastName: "last3"}
}
Sample function for init your array:
function initArray(){
for(var i=1; i< count+1; i++) {
var newElement = {}
newElement.FirstName = "first" + i;
newElement.LastName = "last" + i;
var keyName = "key" + i
var obj = {};
myArray[keyName] = newElement
}
}
Now "myArray["key2"] is accessible.

You can't do what you're trying to do in javascript! (because javascript can't do associative arrays)
I would go for an object which has an internal array to store other things
var container = {};
container.things = [];
container.things.push({FirstName: 'First1', LastName: 'Last1'});
now you can do..
for(var i in container.things) {
alert(container.things[i].FirstName);
}

In JavaScript we use arrays like this, [] for Arrays and Objects are in {}
var MyArray = [
{FirstName: "Firsname1" , LastName: "Lasname1"},
{FirstName: "Firsname2" , LastName: "Lasname2"}
]

myArray[theKey][theIndex].FirstName;' and then loop through it like: for(i=0; i < myArray[theKey].length; i++).... So myArray['key1'][0].FirstName = 'Fred';` etcYour myarray variable construction is in notation of objects of objects.
var myArray = {'key1':
{
'FirstName' : "First1",
'LastName' : "Last1"
}};
In order to access the values should be like array of objects.
var myArray = [
{
'FirstName' : "First1",
'LastName' : "Last1"
},
];
or notation can be like below:
var data = {
code: 42,
items: [{
id: 1,
name: 'foo'
}, {
id: 2,
name: 'bar'
}]
};
