美国云服务器的html中点击图片放大的实现方法:
1.首先创建一个html文件。
2.在html文件中添加html代码架构。
<!DOCTYPE html>
<html>
<head>
<title>图片放大</title>
</head>
<body>
</body>
</html>
3.然后在html代码架构中的body标签里面使用img标签添加一张图片以及使用script标签添加一个函数实现鼠标点击图片放大的效果。
<div style=” width:300px; height:300px;margin-left:auto;
margin-right:auto; overflow:hidden; margin-top:100px;”>
<img id=”img” onmouseover=”bigger()” onmouseout=”smaller()”
src=”http://mat1.gtimg.com/www/images/qq2012/guanjia2.png”
style=”cursor:pointer;width:300px;height:300px;
transition:all 1s ease-out 0s; perspective-origin:bottom;”/>
<script type=”text/javascript”>
var img = document.getElementById(‘img’);
function bigger(){
img.style.width = ‘400px’;
img.style.height = ‘400px’;
img.style.marginTop = “-50px”;
img.style.marginLeft = “-50px”;
}
function smaller(){
img.style.width = ‘300px’;
img.style.height = ‘300px’;
img.style.marginTop = “0px”;
img.style.marginLeft = “0px”;
}
</script>
4.最后可通过浏览器方式阅读html文件查看设计效果。
完整示例代码如下:
<!DOCTYPE html>
<html>
<head>
<title>图片放大</title>
</head>
<body>
<div style=” width:300px; height:300px;margin-left:auto;
margin-right:auto; overflow:hidden; margin-top:100px;”>
<img id=”img” onmouseover=”bigger()” onmouseout=”smaller()”
src=”http://mat1.gtimg.com/www/images/qq2012/guanjia2.png”
style=”cursor:pointer;width:300px;height:300px;
transition:all 1s ease-out 0s; perspective-origin:bottom;”/>
<script type=”text/javascript”>
var img = document.getElementById(‘img’);
function bigger(){
img.style.width = ‘400px’;
img.style.height = ‘400px’;
img.style.marginTop = “-50px”;
img.style.marginLeft = “-50px”;
}
function smaller(){
img.style.width = ‘300px’;
img.style.height = ‘300px’;
img.style.marginTop = “0px”;
img.style.marginLeft = “0px”;
}
</script>
</body>
</html>
