AJAX evaluator and javascript

Greetings,

I am trying to do the following:
on the client browser, when the user clicks on something, I would like
to use the "html evaluator" to send a bit of javascript code back to the
client and execute the javascript code.

Here is the code that I have:

html div id: 'foo';
        onClick: (html evaluator
                callback: [:script |
                        script add: 'var bar ="This is a test"'.
                        script call: 'alert' argument: 'bar']);
        with: 'Show Alert'.

What I am expecting is a Javascipt alert to pop up. What am I doing wrong?

Thanks,
Frank

Have a look at the JavaScript code that is sent back in FireBug or the
Safari Console.

The problem is that when you use 'strings' in Smalltalk you get
strings in JavaScript. No magic here. So 'var bar = "This is a test"'
is a string. Not a variable declaration.

You might want to try:

    script alert: 'This is a test'

Cheers,
Lukas

variable from within the callback of the html evaluator.

If I assume that there is an existing javascript variable called "bar",
how to I get the evaluator to generate "alert(bar)"

Thanks,

script alert: (SUStream on: 'bar')

Have a look at SUScript>>#alert:, this is an example on how to
generate verbatim output.
