我使用js加载大图像，当鼠标悬停以列出缩略图ok时。但不要工作到多重。
如何：悬停 .thumbs .item 属于 boximg_01 或 boximg_02 .... 仅在中加载图像 boximg_1 或 boximg_02 宽度1 js函数。倍数 boximg_* 仅加载元件的img。
现在什么时候悬停 thumbs img 属于 boximg_01 它在两个方向上运行两个大img boximg_01 & boximg_02 ```
$(document).ready(function() {
$(".box-image .thumbs img").hover(function() {
var imgpath = $(this).attr("dir");
$(".box-image .image").html("");
});
});

image {

max-width: 348px;
margin: 0 auto;
float: left;
background: red;
}

thumbs, .thumbs {

width: 100%;
margin: 0 auto;
display: flex;
float: left;
}
.thumbs .item {width: 100px; height: 100px;}

  $(".box-image .thumbs img").hover(function() {
    var imgpath = $(this).attr("dir");
    $(this).closest(".box-image").find(".image").html("<img src=" + imgpath + ">");

# thumbs, .thumbs {

  width: 100%;
  margin: 0 auto;
