The example in this article describes the method of randomly transforming images by clicking the mouse with js. Share it with everyone for your reference. The specific implementation method is as follows:
<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 onClick="swapPic();">
<img name="randimg" src="images/m09.jpg">
</a>
<br>
<font face="Verdana" size="-2">click image to change
</center>
</body>
</html>I hope this article will be helpful to everyone’s JavaScript programming design.
