Below is a sample of an HTML I am using to get Credit card validation.

When the Submit Button is hit the string is sent to the server In return a Text string seperated by commas is sent back.

Example String -> 1,1,1,Approved,212.41,CC Etc. Etc.

Is There any way that via JavaScript can force the html to wait for the response and trap the character string to seperate
and pass down to a server application.

Any Help would be appreciated.

Thanks
Clyde

You mean an onSubmit function that processing the form before sending it to the server?

The String is being sent back to me from the payment server.

It appears on the browser as a string seperated by commas.

No html just text string.

So you want to parse the string once it is returned from processing on the server? You'd set a Javascript variable to hold the value returned. For example, if you were using CGI (I know you're using C but CGI works well with C), something like this may work:


<script type="text/javascript">
var server_parsedArray = "$variable_returned_from_server".split(",");
alert(server_parsedArray);
</script>

Iam Familar with Java Script.

I can see what you are trying to show me.

Refering to the example of HTML, At what point would the java script be put to force the html to wait for the response.

Please excuse my lack of experience.

How are you retreiving the variable into Javascript from the server?

You Have Hit the nail on the head.

I do not know how to to trap the returning string.

Right now it just appears on my browser, as 1,1,1,authorized, Etc.

If the html would wait for the response and put the string into some kind of variable, I could use it.

I am so confused.

To answer your question Jona... That is the part that is the trouble -- getting the server response into a client-side JavaScript variable. The client-side JavaScript solution (which isn't a good one -- and that is what I said in the other forum), involves the use of a hidden IFRAME, the onload event, and the innerHTML property to retrieve the data.

Didn't see that it was cross-posted.

I was trying to provide the server-side solution, by putting the variable into a JavaScript variable, which can be parsed via the split() method. If the server-side script prints the result to the page, it should be able to print the plain text into a JavaScript variable, true?

Meaning... This cannot be accomplished? Or the server isn't printing the results to the page as a variable?
