JavaScript實現自動切換圖片代碼_javascript技巧

本文給大家分享一段js代碼實現自動切換圖片的執行個體代碼，代碼如下所示：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><title> new document </title><meta http-equiv="Content-Type" content="text/html;charset=UTF-8" /><meta name="author" content="" /><meta name="keywords" content="" /><meta name="description" content="" /><link rel="stylesheet" type="text/css" href="" /><style type="text/css"></style><script type="text/javascript">window.onload=init;var n=1; //圖片標記數var dingshi; //讓圖片動的定時器function init(){dingshi=window.setInterval("tupian()",1000);}//更換圖片function tupian(){var obj=document.getElementById("img1");n++;if(n>=4){n=1;}obj.src="yaj_"+n+".jpg";}//滑鼠放上圖片停止function stoptupian(){window.clearInterval(dingshi);}//滑鼠離開圖片動起來function dongqilai(){dingshi=window.setInterval("tupian()",1000);}</script></head><body><img src="yaj_1.jpg" onmouseover="stoptupian()" onmouseout="dongqilai()" id="img1"> </body></html>
