你不能在JavaScript对象键中使用-。如果需要使用-，则必须使用"或'进行转义：
jQuery('.mit div')
.attr({'data-slick':'{"slidesToShow": 3, "slidesToScroll": 1}'});
英文:
You can't have a - in a JavaScript object key. If you need one, then you have to escape it with " or ':
jQuery('.mit div')
.attr({'data-slick':'{"slidesToShow": 3, "slidesToScroll": 1}'
});
