廣告JS程式碼效果大全

2.[滑鼠感應]
    與前面一個程式碼不同的是,當滑鼠移動到廣告圖片上是可以感應顯示另外設定好的廣告大圖效果,下面就是實現效果所需程式碼:

function bigshow(){
    document.all.div_250.style.visibility = 'visible';
    document.all.div_80.style.visibility = 'hidden';
    }
    function bighide(){
    document.all.div_80.style.visibility = 'visible';

    }

3.[允許關閉]

    與前面兩個程式碼不同的是,廣告圖下方增加了一個圖片按紐,允許訪客點選關閉廣告圖片,下面文字框中就是實現效果所需程式碼:

var delta=0.015;
    var collection;
    var closeB=false;
    function floaters() {
    this.items = [];
    this.addItem = function(id,x,y,content)
    {
    document.write('<DIV id='+id+' style="Z-INDEX: 10; 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()',30);
    }
    }
    function play()
    {
    if(screen.width<=800 || closeB)
    {
    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 = '';
    }
    }
    function closeBanner()
    {
    closeB=true;
    return;
    }
   
    var theFloaters = new floaters();
    //
    theFloaters.addItem('followDiv1','document.body.clientWidth-100',0,'<a  href=http://www.dfeng.net target=_blank><img src=ad/doublead/right.gif width=100 height=554 border=0></a><br><br><img src=ad/doublead/close.gif >');
    theFloaters.addItem('followDiv2',0,0,'<a  href=http://www.dfeng.net target=_blank><img src=ad/doublead/ad_ad.gif width=100 height=400 border=0 ></a><br><br><img src=ad/doublead/close.gif >');
    theFloaters.play();


   把上面的程式碼分別另存為兩個JS檔案,然後在想實現此效果的頁面用
   
    <script type="text/javascript" language="javascript1.2" src="*.js"></SCRIPT>
   
    呼叫即可,*代表你另存的檔名!注意修改廣告圖片地址和連線地址!
