可以选择一个属性"；高度“；用Javascript？

我只想在CSS设置的图像中使用一个高度，然后在JS中捕捉这个渐变，并将宽度缩放到高度x2.25

---

可能吗？

您可能需要设置样式或

在本例中，我直接设置样式

const imgEl=document.querySelector（'img'））
console.log（'imgEl height:'，imgEl.getAttribute（'height'））
const divEl=document.querySelector（'div#d1'）
divEl.style.width=String（+imgEl.getAttribute（'height'）*2.25）+'px'

#d1，#d2{
边框样式：实心；
利润率：10px；
高度：100px；
宽度：100px；
}

第一组


div2

尝试或感谢它与Element#clientHeight一起工作！我尝试一下以下以下：：``````````````````````````````````````````````````````````````````````````````````厄厄厄厄厄厄厄厄厄厄厄厄厄厄厄厄厄厄厄UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUVAR=10；var hauteur=document.getElementById（“wlts”）.clientHeight var largeur=hauteur*multipleateur-document.getElementById（“wlts”）.style.width=largeur+“px”``这工作非常好！
