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>
