Accepting an array as function return value

[JKJ]

Hi!

I am trying to read the contents of an array into a HTML listbox and am encountering problems.

First I created a COM object in VB with specific functions I need. One of these functions returns an array with which I would like to fill an HTML listbox in an asp page. I am retrieving the array by mouse click on a button in the asp page, therefor I have written a function in Javascript.

<script language="javascript">
function GetTaglist()
{
var f2 = document.forms("TagSearch");

var COMTag = new ActiveXObject("xIMSRG.clsPIData");
var taglist = new Array();
taglist = COMTag.GetTagList("T01037","cd*");

for(var i=0; i<taglist.length; i++)
{
var opt = document.createElement("OPTION");
opt.text = taglist[i];
opt.value = taglist[i];
f2.searchlist.add(opt);
}
}
</script>

I assign the returned array to my array taglist but when checking this variable it appears to be "undefined". It seems I cannot catch the returned array correctly.

Does anyone know how to accept a returned array in Javascript?

Many thanks!

var nArray = getArray();

function getArray(){
var narr = new Array(1,2,3,4,5);
return narr;
}
nArray above will have the values in the function where narr is created.

Is that what you are looking for?

hello khalidali63,

Your function does exactly what my function GetTagList(...) does: fill and return an array. It is the part "var nArray = getArray();" or as in my case "taglist = COMTag.GetTagList("T01037","cd*");" that does not work.

The array variable "taglist" should be an array filled with the array elements as returned by the COM object function GetTagList(...).

I think that I still have an error in the way I am trying to read the array elements into the array variable "taglist".

I hope I could clarify my question :))

this could only lead to one thing...your array is not being created properly ..
