the following acquisition is empty, how can I get it? Do not use offsetWidth
-sharpdiv {
width: 100px;
height: 100px;
background-color: red;
}
var div = document.getElementById("div")
console.log(div.style.width) if your element is not styled in style , then you can't get it through dom.style.XXX .
you can get it from getComputedStyle . Specific usage
</div>[getComputedStyle]<a>1</a>[currentStyle]<a>2</a>:
var ele = document.getElementById("div");
var style = window.getComputedStyle ?
window.getComputedStyle(ele, "") :
ele.currentStyle;
