我想在滚动时获取一些匹配元素的位置。 但是,每个元素的输出数字相同。
输出:
Object {top: 2480, left: 0}
Object {top: 2480, left: 0}
Object {top: 2480, left: 0}
为什么每个元素的偏移量相同? 滚动时,值也会发生变化。
编辑:好的。该代码段可在此处运行,但不在我的网站上。非常烦人。答案 0 :(得分:0)
问题在于使用.each。
它应该像这样使用:
var $animatedEls = $('.marked');
$(window).scroll(function(e) {
$.each($animatedEls, function(index, item) {
console.log($(item).offset());
}
}
