Question

当我使用焦点事件和滚动事件时，我看到当我通过键盘中的 TAB 键聚焦元素的同时，我与窗口绑定的滚动事件也会被触发。为了满足我的要求，当我使用 TAB 键进行聚焦时，我必须停止触发滚动事件。任何人都可以帮助我吗？

提前感谢有关此问题的任何类型的建议。代码段如下：

＆＃13;

function toggleSection() {
	var elm = document.getElementById("support-bar");
	if(elm.style.right === "") {
		elm.style.right = "0";
	} else {
		elm.style.right = "";
	}
}

function expandIfNot() {
	console.log('Focussed');
	var elm = document.getElementById("support-bar");
	if(elm.style.right === "") {
		elm.style.right = "0";
	}
}

document.addEventListener("scroll", function(){
	console.log('Scrolled New');
	var elm = document.getElementById("support-bar");
	elm.style.right = "";
});
