passing an array from asp to vbscript or javascript 1

[sandravega]

Hi
I'm just trying to accomplish this:
I use asp to recover information from a table into an array.
I use asp because I want it in the server side... where the database is(uh, that's right, isn't it?I'm not sure)
Then I need to pass this array to an client-side function, just to repopulate a <select>. But the code says that something wrong with the array, it can't recognize it nor in vbscript nor in Javascript

I have some button like=

<input type="button" onClick="Repopulate(<%=myarray%>)" value="Repopulate Now!">

and a JavaScript function like

<script language="javascript">
function Repopulate(myarray)
var i;
objSel = document.frm1.myselect;
objSel.options.length = 0;
for (i = 0; i < myarray.length; i++)
{
var obj = new Option();
obj.value = myarray;
obj.text = myarray;
objSel.options[objSel.options.length] = obj;
}
objSel.options[0].selected = true;

end function
</script>

I know the js function does not work, it just don`t recognizes de array.

I asked this in both forums, the javascript and here...

Thank you a lot

Sandra

when you view the source code after the page is finished loading what do you see for myArray being printed out

e.g. (how does this look after the load)
<input type="button" onClick="Repopulate(<%=myarray%>)" value="Repopulate Now!">

Well, thank u 4 answering. It writes something like this, in the code page and in the browser window itself
(I've deleted the font tags...)

onClick="Repopulate(<p>Response object
error 'ASP 0106 : 80020005'
<p>
Type Mismatch
<p>
/central/ABM_rubro.asp
line 449
<p>
An unhandled data type was encountered.

that's kind of what I was expecting.

the problem is you cannot just say myarray and it will send over the array object in all.

You'll need to use the Join() and recreate the array on the client as the parameter in the function call. Then when the event occurs to call the function declare a var in the script and split the string to in all create a new javascript array.

you're input tag would look like this

<input type="button" onClick="Repopulate('<%=Join(myarray,",")%>')" value="Repopulate Now!">

Then when the function is called you will be sending a comma seperated value as in
test,test,test,test


rate off teh bat in your javascript fucntion create the new array to be used then

function Repopulate(myarray) 
myarray = myarray.split(",");
....etc..

the method I suggest using to get it over there is also discussed in this thread earlier today. thread333-843490

Thanks a lot. Really
It seems as I have broken two or more forum rules today... Sorry for that.
I've searched the forum but probably due to my uneasyness with english (I'm a spanish speaker) I couldn't find the answer.
You were helpfull in the asp-vbscript affair, and I'm always trying to improve my "forum" skills, so thank for that kind of help too.
So thanks, thanks and thanks.
