我正在尝试让以下代码工作，但它没有：
$.each($("input, select"), function (index, input) {
input.addEventListener("invalid", function () {
this.scrollIntoView({
behavior: 'smooth',
block: 'center'
});
});
});
这说明的是：对于我的表单中的每个输入和选择，添加一个侦听"无效"状态的事件侦听器(如果任何输入或选择无效，则在提交表单时触发(。事件侦听器将以平滑的动画滚动输入或选择进入页面中心的视图。
但它既不会滚动到页面中心，也不会流畅。我的输入和选择会立即滚动到页面顶部。
将控制台日志添加到事件侦听器告诉我事件侦听器正在响应，"this"确实是指正确的输入或选择：
console.log('this =', this);
那么为什么这对我不起作用呢？

下面是一个演示问题的 JSFiddle：
https://jsfiddle.net/gib65/j1ar87yq/
尝试使用箭头函数，以便this正确绑定到您的回调。
$.each($("input, select"), function (index, input) {
input.addEventListener("invalid", () => {
this.scrollIntoView({
behavior: 'smooth',
block: 'center'
});
});
});
