The code example is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>js获取当前图片宽高的示例</title>
<script type="text/javascript">
function imgSize(){
var myImg = document.querySelector("#sky");
var currWidth = myImg.clientWidth;
var currHeight = myImg.clientHeight;
alert("当前 width=" + currWidth + ", " + "当前 height=" + currHeight);
}
</script>
</head>
<body>
<img src="/static/imghwm/default1.png" data-src="./1/png" class="lazy" id="sky" style="max-width:90%" alt="How to get the width of an image in css" >
<p><button type="button" onclick="imgSize();">获取</button></p>
</body>
</html>When we click the get button, the imgSize() method defined above will be called, and the querySelector() method can get the id="sky" in the document. element, that is, the obtained img image. Then get the current width and height of the element (unit: pixels) through the .clientWidth and clientHeight properties.

clientWidth attribute represents the internal width of the element. This property includes padding but excludes vertical scrollbars (if any), borders, and margins, and its value is rounded to an integer.
clientHeight can be calculated by CSS height CSS padding - the height of the horizontal scroll bar (if present).
