我试图通过调用函数将溢出的flexbox容器的内容从一个div水平滚动到另一个div。
HTML #href和jQuery window.location满足了我的目的，但是他们也将容器滚动到窗口的顶部，而不是仅滚动容器的内容而不改变窗口位置。
我认为解决方案是：
var currentSlideFocus = $("#select_slide_" + currentSlide).position().left;
$("#slideWindow").scrollLeft(currentSlideFocus);
但是，currentSlideFocus的值只是我预期的10％，而scrollLeft的滚动行为量似乎只是currentSlideFocus的10％左右。是什么赋予了？
position（）。left是否测量元素左侧相对于其容器左侧的距离，还是我不正确地解释？
这是下面的骨架化项目的JSfiddle。谢谢。 https://jsfiddle.net/goneZoe/sf46ea03/

我想知道为什么我从position（）获得结果。离开我是，而不是仔细考虑CSS，我重新思考我使用变量的方式，而是走这条路线。奇迹般有效。
singleSlideWidth = $(".slide_frame").width();
slideMeasure = currentSlide - 1;
currentSlideDistance = singleSlideWidth * slideMeasure;
$("#slideWindow").scrollLeft(currentSlideDistance);
