使用原生js实现以下效果:点击容器内的图标,图标边框变成border:1px solid red,点击空白处重置
const box = document.getElementById('box');
function isIcon(target) {
return target.className.includes('icon');
}
box.onClick = function(e) {
e.stopPropagation();
const target = e.target;
if (isIcon(target)) {
target.style.border = '1px solid red';
}
}
const doc = document;
doc.onclick = function(e) {
const children = box.children;
for(let i; i < children.length; i++) {
if (isIcon(children[i])) {
children[i].style.border = 'none';
}
}
}
