How to add Controls Dynamically in RoR?

[dakshayini]

The problem is, i have to add the controls dynamically in html/ruby html which should take the unique id for each controls.
Eg: If i click on add button say,control should create the code as follows..

<input type ="text" name="text1" id="text1">
   <input type ="text" name="text2" id="text2">...
How can i achieve this?Please help.Its urgent

You can use javascript to add new elements. Something like

function addElement() {
  var div = document.getElementById('div1');
  var element = document.createElement('input');
  element.setAttribute('type', 'text');
  element.setAttribute('name', 'text1');
  element.setAttribute('id', 'text1');
  div.appendChild(element);
}

You will need to set the name and id dynamically, maybe by using a counter or something from your ruby code.
