Help required urgently

Bigmous · 10-22-2009, 08:03 AM

I'm in need of some help. currently working on a major php project for uni and am slightly stuck on a form feature that is required.

i've got a drop down menu and an input box next to it. once the user clicks the add button, I need a new drop down and input box to be generated under it. this new row of fields will occur each time they click on the add.

    margin:4px auto;
 }
#theForm input,#theForm select {
    float:left;
    margin:0 5px 10px;
 }
.blue {
    background-color:#ccf;
 }
.red {
    background-color:#fcc;
 }
</style>

<script type="text/javascript">
if(window.addEventListener){
   window.addEventListener('load',init,false);
 }
else { 
if(window.attachEvent){
   window.attachEvent('onload',init);
  }
 }

function init(){

  c=0;
  d=2
  optLength=3;
  opt=[];
  df=document.forms[0];

df[2].onclick=function(){
  addElements();
  }
 }

function addElements() {

   c++;
   dv=document.createElement('div');
   dv.setAttribute('id','container'+c);
if(c%2==0) {
   dv.className='blue';
 }
else {
   dv.className='red';
 }
   sel=document.createElement('select');
   sel.setAttribute('name','select'+c);

for(k=0;k<optLength;k++){
   d++;
   opt[k]=document.createElement('option');
   opt[k].setAttribute('value',d);
if(k==0){
   opt[k].appendChild(document.createTextNode('---options---'));
 }
else {
   opt[k].appendChild(document.createTextNode('option '+d));
 }
   sel.appendChild(opt[k]);
 }
   dv.appendChild(sel);

   inp=document.createElement('input');
   inp.setAttribute('name','input'+c);
   inp.setAttribute('type','text');

   dv.appendChild(inp);

   document.forms[0].appendChild(dv);
 }

Hi there Mous,

this can be easily done with a slight modification.

    background-color:#fcc;
 }
</style>

<script type="text/javascript">
if(window.addEventListener){
   window.addEventListener('load',init,false);
 }

   window.attachEvent('onload',init);

   dv.className='red';
 }
   sel=document.createElement('select');
   sel.setAttribute('name','select'+c);

for(k=0;k<optLength;k++){

   document.forms[0].appendChild(dv);
 }
</script>

</head>
<body>

<form id="theForm" action="#" >

<div id="container0" class="blue">
