A collection of advertising JS code effects
1.[Normal effect]
Nowadays, many website advertisements are in full swing. Now I will introduce the code usage of common couplet floating advertising effect. The effect introduced can be displayed normally at the resolution of 1024*768 and can be displayed at the resolution of 800*600. Automatically hide so as not to cover the page and affect visitors’ browsing content. The following is the code required to achieve the effect:


var delta=0.015
var collection;
function floaters() {
this.items = [];
this.addItem =
function(id,x,y,content)
{
document.write('

' content '

');

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 ()
                                               .style.display = 'none';
}
return;
}
for(var i=0;i { 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('followp1','document.body.clientWidth -100',0,'
theFloaters.addItem('followp2',0,0,'
' target=_blank);
theFloaters.play();

Save the above code as a JS file, and then use it when you want to achieve this effect Just call the page! Pay attention to modifying the ad image address and link address!

Comprehensive list of advertising JS code effects ~~~~~~~~~~

2.[Mouse sensor]
The difference from the previous code is that when the mouse moves over the advertising image, it can sense and display the advertising large image effect set separately. The following is the code required to achieve the effect:

document.all.p_80.style.visibility = 'hidden';

document.all. p_80.style.visibility = 'visible';
