Pass Javascript array to VBS?

[theniteowl]

I am working on an HTA script that uses a bit of Javascript for the on-page data input and validation.
I need to determine how to pass the contents of a javascript array over to VBScript.

My VBS code parses through a log file looking for matching strings of text in a VBS array. I just have to determine how to send the contents of the Javascript array to the VBScript array.

Thoughts?

You could write the contents of the array to a file from the javascript and then read it back into the VBS?

Hope This Helps, PH.

Yes that would work, it would just be a bit inelegant when it should be possible directly in the code.

Unfortunately PHV, this is an HTA app that is not running on an IIS server. I had seen that site in my searching but could not see how it could be readily applied to my situation.

As a workaround I setup a javascript function that calls a VBScript function in a loop passing the array elements one at a time. The VBScript function ReDims the VB array and adds the new element.

This would not be a good solution if I were passing a LOT of data but I will probably be passing only 4-5 elements. Each element can contain a short or fairly long text string though so I did not want to pass it all as one big delimited string.

This seems to be working. My next alternative would have been to write it all out to a hidden form field and read it back in from the VBScript side and parse it out into an array.
