Topic awaiting preservation: why this isn't working? isn't it standard?

I was surprised to see that this code doesn't work on IE5 but works on IE6!

var x = {'obj1':[1,2,3], 'obj2':[2,3,4], 44:['hey', 'ho!']}


IE5 needs 'x' to be defined line by line for each element as it seems...
x = new Object;
x['obj']=[1,2,3]
.
.
.
// for IE5

is that true or i have a problem in my initial object construct?

shouldn't it be:

var x = {'obj1':[1,2,3]; 'obj2':[2,3,4]; 44:['hey', 'ho!']}

with semi-colons for delimiters?

I don't really understand what you're trying to do, somewhere between a hash and an array, methinks...

He's defining an object using the literal syntax. Just like an array can be defined with

myarray = [1,2,3,4,5];

an object can be defined with

myobject = {prop:'value', prop2:'value'};

Lallous, two problems with your script:
1. the property names shouldn't be quoted. They're not strings, they're properties... just like the x in 'var x' isn't quoted, obj1 and obj2 shouldn't be quoted.
2. you can't have a number like 44 be a property. All variables/properties must begin with a letter or underscore.

The correct assignment would be:

var x = {obj1:[1,2,3], obj2:[2,3,4], obj3:['hey', 'ho!']}

The reason x['obj'] = [1,2,3] works is because the [] operators take a string and convert it into a property. The object literal syntax doesn't do that.

Hi Slime,

weird...the 'obj1' as property name works as quoted! I'll try that with IE5 but unquoted.
as for the property as numbers...I have been using these as a mean of key indexed array as in php, and they have been working just fine!

as I said before too, that if defined on seperate lines (not literal) for both quoted properties names and numeric properties, they all work.

After testing on IE5

1. the property names shouldn't be quoted. They're not strings, they're properties... just like the x in 'var x' isn't quoted, obj1 and obj2 shouldn't be quoted.

they work quoted just fine when quoted/unquoted.

2. you can't have a number like 44 be a property. All variables/properties must begin with a letter or underscore.
You're right about numbers in ie5 and this case.
But they will work if you quote them as: {'55':[1,2,3]}

that's all.

Ah, but what works in Intenet Explorer rarely coincides with what's *allowed*. =)

My javascript book doesn't mention putting quotes around the properties in object literals, so I'm making the assumption that they're not allowed. Someone could check the ECMA spec if they're really interested =)
