Javascript help
<p>I am very new to javascript. I want to add the same effect as that given in the text fields of this webpage in my own page... Can any one help me with how to do it or where to learn it from.</p>

<p>I want my text fields to show what have to be written there but it will change as soon as I write something in it..</p>

<p>Another thing is that a small popup block will appear when I click on a textbox which describes what and how to write in it... like password should be alpha numeric... or more than 6 character long ect..</p>

<p>Thanks...</p>
