Help with function to determine listbox contents

[tks423]

Hi,

I was wondering if this is correct code for determine the contents of
a listbox. I'm particularly interested to know if the
sel1.options[i].valueOf() call will tell me the value of the item as
it loops through the for statement:

function listBoxContents(sel1)
{
var selLength1 = sel1.length;
var i;
var values;

for(i=0; i<=selLength1-1; i++)
{
values=sel1.options[i].valueOf() + ",";
}
var lastComma = values.lastIndexOf(',');
values = values.substring(0,lastComma);

return values;
}

for(i=0; i<selLength1; i++)
values+=sel1.options[i].value+ ",";
return values.slice(0,-1)
}

}

Thanks! Now say I want to hide this return value in hidden input, can
I say something like below:

function listBoxContents(sel1)
{
var selLength1 = sel1.options.length,i,values='';

for(i=0; i<selLength1; i++)
values+=sel1.options[i].value+ ",";
document.writeln("<input type='hidden' name='hiddenValues' value='"
+ values.slice(0,-1) + "'>");
}

var input=document.createElement("input");
input.name="hiddenValues";input.type="hidden";
input.value=values.slice(0,-1);
document.body.appendChild(input);
