Get Array Name

Hi,

Do anyone, Knows, How to get array Name?

Like If I have a array:
abc & I would like to get the name abc, How can I do that.
I am trying to set abc.name but its not working.

I have to get the array name, so that I can change them dynamically.
What to do?

(...that is, unless you assign them a .name property yourself, which
does in fact "work")

If you're asking how to find out the name of a variable that holds a
reference to an array, you're probably doing something else wrong. If
that's not what you were asking, maybe you should give a little more
sample code than "abc".

Assuming the code you have that wants to "do stuff" with an array takes
that array as a parameter, then why not make the caller pass in the
array name as a string. Example:

var myarray=[];
function doStuffTo(somearrayname)
{
window[somearrayname][0]="cool array[0] string";
}

doStuffTo("myarray");
Can you explain more about what you mean by changing "them" dynamically.

What do you mean excactly?

var myArr = [1,2,3];
var meToo = meArr;
hereIsAnArr(myArr);

function hereIsMyArr(someArr){
// do you want to find the name of the arr here?
// Then what name? myArr or meToo?
}

The 'name' of an array is just a variablename available in a certain
scope that POINTS TO (=reference) an array.
(I hope I phrased that right.)

Maybe I misunderstand what you mean. If so, please clarify.
