使用HTML+CSS+Javascript 制作——当鼠标点击屏幕时,出现星星闪烁的效果
实现代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style>
*{
margin: 0;
padding: 0;
}
</style>
</head>
<body>
<script>
document.body.style.backgroundColor = "#000"
document.onclick = function(event){
let img = document.createElement("img")
img.src = "0.gif"
img.style.position = "absolute"
document.body.appendChild(img)
img.onload = function(){
const img_w = parseInt(getComputedStyle(img).width)
const img_h = parseInt(getComputedStyle(img).height)
w = getRandom(50, 200)
h = img_h/img_w * w
img.style.width= w + "px"
img.style.height = h + "px"
img.style.left = (event.pageX - w/2) + "px"
img.style.top = (event.pageY - h/2) + "px"
}
}
function getRandom(min, max){
return min + Math.ceil((max - min)*Math.random())
}
</script>
</body>
</html>
