Get all array indices?

[jagi]

Hi,

I have an object array to store all the text-boxes that have been changed. (cell-ids along with values)
The function looks like this:

function fnEditData(textObj) {
var parentTDCell = textObj.parentNode;
textValObj[parentTDCell.id] = textObj.value;
computePltTotals(textObj);
computeMktTotals(textObj);
}

I pass this textValObj[] to another page.
Now my question is, how can i retrieve all the indices of the array as a collection?

Can anyone help?

thanks.

Why do you need to access the array as a collection when you can access it as an array? The methods for accessing both are identical most of the time.

Incidentally, you are not storing the cell ids - you are storing a pointer to the cell element itself. Just in case you are having grief with that one ;o)

Hope this helps,
Dan

Actually I want to be able to access the indices in the array.
Can i do that?

If you mean that you want to be able to access any individual object within your array, the answer is yes. You would access it no differently on the page you are passing it to, as you would on the page it is declareed on.

Of course, this assumes that you are passing the array as an array, and not as a string or some other data type.

I have this object array:
var textValObj = new Array[10];
textValObj['abc_08/30/04'] = '30.0';
textValObj['xyz_09/01/04'] = '72.5';
...

How can I get all the string indices from the array textValObj?
(indices: 'abc_08/30/04', 'xyz_09/01/04')

Any ideas ?

To get an array of the "key" values, you can do this:

var keys=[];
for(key in textValObj){
  keys[keys.length]=key;
}

I got confused by what you mean there, Dan. parentTDCell.id is a string, not an object. I don't understand how he's storing a pointer.

Thank you all.

Ah yes - good point Adam.

I was referring to the previous line of code, but it turns out I totally misread it. Thanks for clearing that one up.
