Javascript實現帶關閉按鈕的網頁漂浮廣告代碼
帶有關閉功能的漂浮圖片的實現方法有很多，下面為大家介紹下使用Javascript是如何實現的，喜歡的額朋友可以了解下
代碼如下: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <title>帶關閉按鈕的網頁漂浮廣告代碼</title> </head> <body> <div id="img" style="position: absolute; left: 311; top: 815;visibility :hidden;" onmouseover="clearInterval(interval)" onmouseout="interval = setInterval('changePos()', delay)" align="right"> <a href="#" target="_blank"><img border="0" src="圖片路徑" onload="return imgzoom(this,600);" onclick="javascript:window.open(this.src);" style="cursor:pointer;"/></a> <span style="CURSOR:hand;color:red;font-weight:bold" onclick="clearInterval(interval);img.style.visibility = 'hidden'">X</span> </div> <script language=javascript src=ff.js> </script> </body> </html> ff.js代碼 代碼如下: var xPos = 20; var yPos = document.body.clientHeight; var step = 1; var delay = 30; var height = 0; var Hoffset = 0; var Woffset = 0; var yon = 0; var xon = 0; var pause = true; var interval; img.style.top = yPos; function changePos() { width = document.body.clientWidth; height = document.body.clientHeight; Hoffset = img.offsetHeight; Woffset = img.offsetWidth; img.style.left = xPos + document.body.scrollLeft; img.style.top = yPos + document.body.scrollTop; if (yon) { yPos = yPos + step; } else { yPos = yPos - step; } if (yPos < 0) { yon = 1; yPos = 0; } if (yPos >= (height - Hoffset)) { yon = 0; yPos = (height - Hoffset); } if (xon) { xPos = xPos + step; } else { xPos = xPos - step; } if (xPos < 0) { xon = 1; xPos = 0; } if (xPos >= (width - Woffset)) { xon = 0; xPos = (width - Woffset); } } function start() { img.style.visibility = "visible"; interval = setInterval('changePos()', delay); } start();javascript排行
