Ajax dynamic form

Hi all,

I am to develop a form which using Ajax to submit data, the traditional way I used as it has static Text field and with onKeyUp for user to input something. But recently I found that there've some websites using a dynamic method as :

1. User click the Text, for example: I am a boy
2. "I am a boy" change to a text field to let user to change content directly
3. The cursor leaves the text field, record updated.
(The most usage on this techni. I found as Facebook)

I believed it's something about Ajax, since I am new to that, I would like to know how to do this? is that using a CSS layer control? (when click, change to viewing Form layer)

Any hints for me to reach that?

Many Thanks,

hi Eric,

here's simple way.

var editMode = false;
function changeThis(obj)
	if(!editMode) {
		editMode = true;
		obj.innerHTML = "<input onblur='saveAndChangeThis(this)' type=text value='"+obj.innerHTML+"'>";
function saveAndChangeThis(obj)
	obj.parentNode.innerHTML = obj.value;
	editMode = false;
<span id=spnContent onclick=changeThis(this)>I am a boy</span>
