How do I get the length of an Array? 1

[bigfoot]

this is my code:

function MyThing(va, vb)
{
this.va = va
this.vb = vb
}

var NewThing = new MyThing(4)
NewThing[0].va = "varA"
NewThing[0].vb = "VarB"
NewThing[1].va = "varA"
NewThing[1].vb = "VarB"
.....

How do I do NewThing.Length?

I would think it would be 4? But it's null

ohh... nevermind... you cant get the length of your object... it doesn't have a length property...

you object isn't an array... you can put your objects in an array though...

var x = new Array()
x[x.length] = new MyThing(); adam@aauser.com

I tried this:
function mything(a,b)
{
this.a = a
this.b = b
}

thething = new Array(3)

thething[0] = new mything("aaa","bbb&quot

thething[1] = new mything()
thething[1].a = "1"
thething[1].b = "2"

document.writeln(thething[0].a + &quot;<br>&quot;
document.writeln(thething[0].b + &quot;<br>&quot;
document.writeln(thething[1].a + &quot;<br>&quot;
document.writeln(thething[1].b + &quot;<br>&quot;
document.writeln(thething.length + &quot;<br>&quot;

Is there anything wrong with doing it this way?

that doesn't work? it worked for me... adam@aauser.com

Yes, the last code worked, but I'm asking if there's anything wrong with doing it this way?

I'm new to JavaScript objects. In Visual Basic you need to set them to nothing and do more coding to keep from getting memory leaks.
JS arrays are too easy. I have to forget all I learned in VB The door to life is never locked, but few have the knowledge to open it.
