RE: Help me - how to pass retreived database values toJavascript
This is starting to get a bit off-topic but what I think you're alluding to
"Associatve Arrays" (collections by any other name)
Here's an example of how to use them.
<html>
<head>
<script>
var myarray={
#foreach ($item in $list)
'text$velocityCount':'$item',
#end
}
</script>
</head>
<body>
<form name="steve">
<input type="text" name="text1" size="20"><br>
<input type="text" name="text2" size="20"><br>
<input type="text" name="text3" size="20"><br>
<input type="text" name="text4" size="20"><br>
<input type="text" name="text5" size="20"><br>
</form>
<button onclick="document.steve.text4.value=myarray['text4']">Click here to
assign a value to a box using it's name</button>
</body>
</html>

I'm guessing that you're trying to do something like this;
<script>
var myarray=[
#foreach ($item in $list)
'$item',
#end
]
</script>
This creates a javascript array (the last element is empty, but you get
the
idea).

Writing Javascript with Velocity can be a little tricky, but just
remember that you use Velocity to set the values for constant fields
acted on by the Javascript function.
Do not write a Javascript function that tries to manipulate a Velocity
context object at runtime, because the Velocity context is not
available once the request leaves the server. Javascript is run by
the client browser, which has no access to Velocity.
