in php I could do:
$prices['ford']['mondeo']['2005'] = 4500;
$prices['ford']['mondeo']['2006'] = 5500;
$prices['ford']['mondeo']['2007'] = 7000;
and could do:
echo sizeof($prices['ford']); // output 1
echo sizeof($prices['ford']['mondeo']) //output 3
how can I achieve it in Flash. Flash doesn't seems to like STRINGS as ARRAY KEYS, does IT ?
To have associative array -like functionality, you can use an Object;
var prices:Object = new Object();
prices.ford = new Object();
prices.ford.mondeo = new Object();
prices.ford.mondeo['2005'] = 4500;
prices.ford.mondeo['2006'] = 5500;
prices.ford.mondeo['2007'] = 7000;
or simply
var prices:Object = {
ford: {
mondeo: {
2005: 4500,
2006: 5500,
2007: 7000
}
}
};
Actionscript doesn't have a built in function resembling sizeof in php, but you can easily write one of your own:
function sizeof(o:Object):Number {
var n:Number = 0;
for (var item in o)
n++;
return n;
}
And just use it like in php:
trace(sizeof(prices['ford'])); // traces 1
trace(sizeof(prices['ford']['mondeo'])); // traces3
Arrays are indexed by integers in Flash, if you want to index on a string use an Object instead.
events['abc']=Array(Array('yes','no')) what command will add another array to events['abc'] ??
events.abc.push('may be'); But remember that after this line events.abc contains [['yes', 'no'], 'may be'] instead of ['yes', 'no', 'may be'] as you might expect.var array:Array = [];
array['name'] = "the name";
array['something'] = "something else";
trace(array.length);
It traces 0. So yeah, flash doesn't really like strings as array keys though it is allowed. Array is a dynamic class (like Object) where you can add properties to individual objects as you want. array['name'] = "myname" is same as array.name = "myname".
That said, you can assign an array to array['name'] and read its length.
var array:Array = [];
array['name'] = new Array();
array.name.push(1, 2, 3);
trace(array.length);//traces 0
trace(array.name.length);//traces 3
