Getting an array var from asp

[Fuzemmo]

I have an array in my asp code that I want to access in a javascript. I found an example of doing this, but it was for a non-array var. I can access an individual array element via:

var myVar = "<%=arrImages(0)%>";

I can also access the "count" for the array, so I can get the entire thing with a loop. But is there a way for me to get the entire array in one hit? I've tried the following:

var myArray = Array()
myArray = "<%=arrImages%>"
or
myArray = "<%=arrImages()%>"

Neither of those seemed to work.

Any suggestions?

If you use JavaScript for your ASP page language, this should work:

var myArray = '<%=arrImages().join('|')%>'.split('|');

Hope this helps,

Oops sorry. That should have read:

var myArray = '<%=arrImages.join('|')%>'.split('|');

I'm using vbscript in my code-behind. I know its ugly, but I ended up using a work-around of converting my array in the code-behind to a pipe-delimitted string, and then just pulling that value over and parsing it back into an array format in the javascript. (Lord have I got a long ways to go.)

In other words, you did it exactly the way Dan showed, except in vbscript instead of javascript?

Another method I have used is to build the javascript array as I get the data.
In this example I am pulling the data from a recordset but you can apply the same concept to either writing the content of your ASP array to a javascript one, or creating just the javascript side one as you get the data in the first place.

' Write the javascript header
response.write "<SCR" & "IPT LANGUAGE=""JavaScript"">" & vbCrlf
' then declare the array
response.write "var assigneelist = new Array();" & vbCrlf
out="assigneelist = ["
do until rs.eof
' Store all Assigneed info for selected group in Client Side Javascript array assigneelist
If cnt <> 0 then
out = out & ","
End if
cnt=cnt+1
out = out & "'" & rs(0) & "','" & rs(1) & "','" & rs(2) & "','" & rs(3) & "','" & rs(4) & "'"
rs.movenext
loop
out = out & "];" & vbCrLf
response.write out
' write the script trailer...
Response.Write "</SCR" & "IPT>" & vbCrlf


Essentially you just create a string that is a javascript block instantiating the array then write it out.
