滚动加载时，来自数据库的更多数据无法在IE 11中运行

Question

I trie to load more data on scroll to the bottom. All works fine in Edge,Chrome,Firefox but not in IE 11. Nothing happens there

Here's my Code:

$(window).scroll(function() {
    if ($(document).height() <= $(this).scrollTop() + $(this).height()) {
        if (timer) {
            window.clearTimeout(timer);
        }
        timer = window.setTimeout(function() {
            // Magic goes here
        }, 400);
    }
});

Meta Tag is set to

<meta http-equiv="X-UA-Compatible" content="IE=edge">

Many thx

EDIT

If i open the debug mode on IE , everything works fine. No errors

Just tested your code example on IE11 and works perfectly fine. Here is the test code i ran in the browser:

var timer;

$(window).scroll(function(){        
    if ($(document).height() <= $(this).scrollTop() + $(this).height()) {
        if(timer) {
            window.clearTimeout(timer);
        }
        timer = window.setTimeout(function() {
            alert('bottom of page');
         });
     }
});

Are there any errors thrown in your console on IE11? Sharing more of the code in question would help, as there is no inherent reason for the example you have given to not work on IE11.
