我jQuery用来检查 adiv是否滚动。它适用于window，但不适用于特定的 div。
Works fine:
工作正常：
$(window).scroll(function() {
console.log('scroll happened');
});
Not Wokring Fine:
不工作很好：
$('.ui-multiselect-checkboxes').scroll(function(){
console.log('scroll happened');
});
HTMLI am using ERIC Hynds Multiselect. So scroll is present on its ulwith class ui-multiselect-checkboxes. You can see live example here
HTML我正在使用 ERIC Hynds Multiselect。所以滚动出现在它ul的 class 上ui-multiselect-checkboxes。你可以在这里看到现场示例

Try:
尝试：
$(document).on('scroll', '.ui-multiselect-checkboxes', function(){
console.log('scroll happened');
});
This is because these elements are dynamically created by multiselect plugin.
这是因为这些元素是由多选插件动态创建的。

创建委托事件，因为这些事件是由您的多选插件动态创建的。
$(document).on('scroll', '.ui-multiselect-checkboxes', function(){
console.log('scroll happened');
});

Try something like this
尝试这样的事情
$(document).ready(function(){
$('.ui-multiselect-checkboxes').bind('scroll',chk_scroll);
});
function chk_scroll(e)
{
var elem = $(e.currentTarget);
if (elem[0].scrollHeight - elem.scrollTop() == elem.outerHeight())
{
console.log("Scrolled");
}
}
回答by Pratik
Solved
解决了
<script>
$(function() {
$(".ui-multiselect-checkboxes").on('scroll', function () {
console.log('scroll happened');
});
});
</script>
//OH I CHECKED ITS WORKING. Now
//哦，我检查了它的工作。现在
Just check place all files you have in header of this HTML ,just Create a folder and place files accordingly inside "jQuery MultiSelect Widget Demo_files" FOLDER
只需检查将所有文件放置在此 HTML 的标题中，只需创建一个文件夹并将文件相应地放置在“jQuery MultiSelect Widget Demo_files”文件夹中
And then check console //NEW SOLUTION
然后检查控制台 //NEW SOLUTION
