JQuery function-left and right jitter effect, used for prompting

If the WordPress blog background login input is incorrect, the login window will be jittery. Make it easy to call jQuery functions (the jQuery package has been loaded on the premise)

Function shake (o ){
Var $ panel = $ ("#" + o );
Box_left = ($ (window). width ()-$ panel. width ()/2;
Using panel.css ({'left': box_left, 'position': 'absolute '});
For (var I = 1; 4> = I; I ++ ){
$ Panel. animate ({left: box_left-(40-10 * I)}, 50 );
$ Panel. animate ({left: box_left + 2*(40-10 * I)}, 50 );
}
}

The parameter o of the shake function is the ID of the dom element, which is generally the ID of the div. Shake ('panel '); a simple call can achieve the effect of left and right jitter .. I used it to prompt that it was quite good.
