Body {font-size: 9pt}
Textarea {color = "#707888"; font-family: "verdana "}
. Inputs {color = "#707888"; border: 1px solid; background: # f4f4f4}
</Style>
Enter the format you want to convert, either JavaScript or DHtml.

<Textarea id = "codes" style = "width: 730; height: 300">

Advertisement JS Code Effect Daquan
1. [Normal Results]
Nowadays, many website advertisements are in full swing. Now I will introduce the common code usage methods for floating couplet advertisements. The results are displayed at a resolution of 1024*768, the image can be automatically hidden at a resolution of 800*600 to avoid page hiding affecting the visitor's browsing content. The following code is required to achieve the effect:

Var delta = 0.015.
Var collection;
Function floaters (){
This. items = [];
This. addItem =
Function (id, x, y, content)
{
Document. write ('<DIV id =' + id + 'style = "Z-INDEX: 0; POSITION: absolute; width: 80px; height: 60px; left:' + (typeof (x) = 'string '? Eval (x): x) + '; top:' + (typeof (y) = 'string '? Eval (y): y) + '">' + content + '</DIV> ');

Var newItem = {};
NewItem. object = document. getElementById (id );
NewItem. x = x;
NewItem. y = y;

This. items [this. items. length] = newItem;
}
This. play =
Function ()
{
Collection =
This. items
SetInterval ('play () ', 10 );
}
}
Function play ()
{
If (screen. width <= 800)
{
For (var I = 0; I <collection. length; I ++)
{
Collection. object. style. display = 'none ';
}
Return;
}
For (var I = 0; I <collection. length; I ++)
{
Var followObj = collection. object;
Var followObj_x = (typeof (collection. x) = 'string '? Eval (collection. x): collection. x );
Var followObj_y = (typeof (collection. y) = 'string '? Eval (collection. y): collection. y );

If (followObj. offsetLeft! = (Document. body. scrollLeft + followObj_x )){
Var dx = (document. body. scrollLeft + followObj_x-followObj.offsetLeft) * delta;
Dx = (dx> 0? 1:-1) * Math. ceil (Math. abs (dx ));
FollowObj. style. left = followObj. offsetLeft + dx;
}

If (followObj. offsetTop! = (Document. body. scrollTop + followObj_y )){
Var dy = (document. body. scrollTop + followObj_y-followObj.offsetTop) * delta;
Dy = (dy> 0? 1:-1) * Math. ceil (Math. abs (dy ));
FollowObj. style. top = followObj. offsetTop + dy;
}
FollowObj. style. display = '';
}
}

Var theFloaters =
New floaters ();
TheFloaters. addItem ('followdiv1 ', 'document. body. clientWidth-100 ', 0, '</a> <br> <a href = aD link address target = _ blank> </> 'target = _ blank );
TheFloaters. addItem ('followdiv2', 0, 0, '<br> <a href = aD link address target = _ blank> </a>' target = _ blank );
TheFloaters. play ();

Save the above Code as a JS file and call it on the page to achieve this effect! Modify the ad image address and connection address!
