Question

ok. I have a dropdown. well call it dropdownA. I have several arrays already fashioned, that i want to loop through, and put each individual value out onto the page into it’s own input field, based on the selection in the dropdown. I know how to put together the loop to get the values out onto the page. anyway, here is the meta code.

meta1array=new Array('','','','','','');
meta2array=new Array('','','','','','');
meta3array=new Array('','','','','','');

function metacode(id){
    {
var a=get.the.dd.selIndex;
var b=get.the.dd.options[a].value; //comes back as 'meta1'. other opts are meta2, meta3
var c=b+'array';

for(i=0;i<c.count;i++)
 {
  loop here to popout values
  }
}

i have looked everywhere, and i haven’t come up with anything. I also admit that my brain is starting to mushify from a few weeks straight of coding, and this is the first time i have come across this. so, please. i would be greatful for any help.

Answer 1

metaobject = {
               meta1array: ['','','','',''], 
               meta2array: ['','','','',''], 
               meta3array: ['','','','','']
             };

// snip

var arr = metaobject[b + 'array'];
for(var i=0;i<arr.length;i++) {
    //do work
}
