scrollIntoView的语法

用法如下:

element.scrollIntoView();
element.scrollIntoView(true);
element.scrollIntoView(alignToTop);
element.scrollIntoView(scrollIntoViewOptions);

alignToTop是一个布尔值，true 元素对齐到祖先元素的顶部，false 元素对齐到祖先元素的底部，默认是true
scrollIntoViewOptions是一个布尔值或以下选项的对象：

{
     behavior: 'auto' | 'instant' | 'smooth',
     block: 'start' | 'end'
}
