当目前的div差不多达到下限时,我试图滚动到下一个div。
我正在使用jQuery插件MouseWheel。我有以下代码,滚动时运行动画scrollTop。但是当它达到某个期望点时才会达到它的下限。因为,某些div包含大量带图像的文本。
这是结构HTML
<html>
[...]
<body>
<div id="main">
<div class="item">
[Only a Image]
<!-- Only a Img? I'm 2px distance to the next div OK, ScrollTop When Scroll1 -->
</div>
<div class="item">
[Some Text]
<!-- mmmm Some text. Ok, I let you read this.. Scroll 1.. Scroll 2.. Scroll 3..
Wait! I'm 40px distance to the next div ... scrollTop -->
</div>
<div class="item">
[Some text with Image]
<!-- mmmm Some text with Image. Ok, I let you read this.. Scroll 1.. Scroll 2.. Scroll 3.. Scroll 4... Scroll 5.. Scroll 6..
Wait! I'm 40px distance to the next div ... scrollTop -->
</div>
<div class="item">
[....]
</div>
</div>
</body>
</html>
这是JS:
$('#main').on('mousewheel', '.item', function(e) {
if (e.deltaY < 0) {
$('html, body').animate({
scrollTop: $(e.currentTarget).next().offset().top
}, 1000);
} else {
$('html, body').animate({
scrollTop: $(e.currentTarget).prev().offset().top
}, 1000);
}
e.preventDefault();
});
答案 0 :(得分:0)
将元素的高度添加到偏移量
$('#main').on('mousewheel', '.item', function(e) {
if ($(document).scrollTop() >= $(e.currentTarget).offset().top+$(e.currentTarget).height();) {
$('html, body').animate({
scrollTop: $(e.currentTarget).next().offset().top;
}, 1000);
}
e.preventDefault();
});
