i've got another problem. i guess it's just a stupid mistake, but i just don't get it. so maybe you can help me.
I've got a few text input fields with a "default"-value. onClick in the field the value disappers and the user can insert the data. on blur the "default"-value should appear again, if the field is empty.
This works only, if i klick to the field an blur instantly. if i write something to the box, blur, and focus it again and delete all text and blur, it doesn't work anymore.

the jquery-code is as following:

Here's a fiddle of my code: <http://jsfiddle.net/xQ7jt/>
that's my focus-function. the rest of the code is in the fiddle

```
    $(document).on('focus', '.insert_adresse', function() {
           // $(this).css('background-color', 'yellow');
            $(this).attr('value', '');
        });

```
