本文实例讲述了js鼠标点击图片实现随机变换图片的方法。分享给大家供大家参考。具体实现方法如下：
<html> <title>鼠标点击图片即可随机变换图片</title> <body bgcolor="#fef4d9" OnLoad="swapPic()"> <center> <SCRIPT LANGUAGE="JavaScript"> <!-- Begin var rand1 = 0; var useRand = 0; images = new Array; images[1] = new Image(); images[1].src = "images/m01.jpg"; images[2] = new Image(); images[2].src = "images/m02.jpg"; images[3] = new Image(); images[3].src = "images/m03.jpg"; images[4] = new Image(); images[4].src = "images/m04.jpg"; function swapPic() { var imgnum = images.length - 1; do { var randnum = Math.random(); rand1 = Math.round((imgnum - 1) * randnum) + 1; } while (rand1 == useRand); useRand = rand1; document.randimg.src = images[useRand].src; } // End --> </script> <a> <img name="randimg" src="images/m09.jpg"> </a> <br> <font face="Verdana" size="-2">click image to change </center> </body> </html>
希望本文所述对大家的javascript程序设计有所帮助。
