Data from select box to formbox a.l.a Hotmail, yahoo etc

[-[ CaMeL ]- a55m0nk]

hey there

for my website, i am trying to create a messaging system and so far am
nearly finished, except for one thing. I am not sure how i can get
data from a select form box into a normal data box, and then seperate
them with a "," after every one.

Well, just iterate thorugh the options of your select box, buffer their
value and output the buffer into the text box. An example follows.
<form action="foo">
<select name="a">
<option value="Lu***@grandline.com">Luffy</option>
<option value="Zo***@grandline.com">Zorro</option>
<option value="Na**@grandline.com">Nami</option>
</select>

<input type="button"
value="&gt;&gt;"
onclick="transform(
this.form.elements['a'],
this.form.elements['b']);">

<input type="text" name="b">
</form>

<script type="text/javascript">
function transform(src, dest){
var a=[];
for(var ii=0; ii<src.options.length; ii++)
a[ii]=src.options[ii].value;
dest.value=a.join(",");
}
</script>

The following, while much more attractive, unfortunately doesn't work in
IE (but is fine in Mozilla).

Option.prototype.toString=function(){
return this.value;
}

function transform(src, dest){
dest.value=Array.prototype.join.call(src.options);
}

Yep.
