The jQuery CSS effect is lost when render :action=>edit, how to get rid of it?

In my UI edit.html, I have

<input type='text', id='name'></input>

and I have

<p>Name:</p>

The, I have a javascript file which will use jQuery to css the style of the UI:

$('<p></p>').css('margin-left', '20px').insertAfter($('#name'));

The above CSS will locate <p> element to be located 20px the right side of <input>.

Everything is fine when my app firstly load the edit.html page, the CSS style is there.

BUT, when the model validation is failed, and in my controller, I use

render :action=>edit,

the CSS style feature is lost;

however if my controller use

redirect_to :action=>edit, :id=>@user,

the CSS style is there as expected.

Why my jquery defined CSS style is lost if I use render :action=>edit to render this page. How to get rid of this? I would like to use render :action=>edit w开发者_运维技巧hile keep my jQuery defined CSS taking effect.
