This will not do a JavaScript on the fly but will create a new HTML OPTION
list for a SELECT in JavaScript (on the fly)
//*********** JavaScript code
arry[0] = new Array('Item1','Item2','Item3');
arry[1] = new Array('Item4','Item5','Item6');
function setOptions(thisArry) {
yourForm.yourSelect.length=arry[thisArry].length+1;
for (i=0;i<arry[thisArry].length;i++) {
nuOption = new Option(arry[thisArry][i], arry[thisArry][i],false,false)
;
yourForm.yourSelect.options[i+1]=nuOption;
}
}
//*********** HTML
.
.
........<form id="yourForm">
<select id="yourSelect"></select>
//***********
When you call "setOptions(0)" your select list will read Item1, Item2,
Item3. Calling "setOptions(1)" your select list will read Item4, Item5,
Item6. There is a better way to do all of this using DOM (which would be a
way to do the Javascript on the fly via XML) but earlier browsers like
Netscape 4.x do not support DOM. BTW you can set the "false" to true and
the item will be the selected Item.
