Default Few Questions related to jquery code on p.387..

Hi Imar,

I've started the chapter on Jquery and find it very interesting. I was a little confused about a few things related to the code on p.387.

...function().one('focus' function ()
{ this.value='', this.className=''}).addClass('Watermark').css('wid th', '300px');

(1) Why do you need to reset the Css class to an empty string, this.className='' ?

(2) Also, how did you know to set the width to 300px?

Thanks.
Tulsi

Hi Tulsi,

1) By setting it to an empty string, the CSS class is removed and thus the watermark disappears.

2) The text boxes the watermark is applied to are 300px wide as well....

Thank you.

The Jquery syntax was a little confusing at first, but now I understand this.
