jquery - in keyDown erase text from input

Question

I have a input box that i have some text in site

<input type="text" value="Enter Name"/>

Now i need to add that when the user starts typing in something (enters the first letter), my text will disappear and he will be able to enter the input he wants.

I tried doing:

$('#input').keypress(function () {
                $(this).val("");
            });

But then the user can only enter one letter cuz it keeps on deleting the text.

How can this be done?

Thanks

You can do this by using a placeholder

Some browser doesn't yet support this, adding a fallback could also be a good idea to support it cross browser: http://davidwalsh.name/html5-placeholder

UPDATE: You can do what you ask for like this: http://jsfiddle.net/9VhYZ/1/

$('#input').one("keydown", function () {
    $(this).val("");
});
