As an alternative, for those who likes more programmatic ways and syntax:
作为替代方案，对于那些喜欢更多编程方式和语法的人：
$('#container-element img').last().remove();
回答by CMS
You can use the :last-childselector to find the last appended element, then you can removeit:
您可以使用:last-child选择器来查找最后一个附加元素，然后您可以将其删除：
$('img:last-child', this).remove();
// get the last img element of the childs of 'this'

The code from the original question may generate errors (using "this" with the selector). Try the following approach:
原始问题中的代码可能会产生错误（在选择器中使用“this”）。尝试以下方法：
$("#container-element img:last-child").remove()

太棒了，非常感谢尤金，这真的帮助了我。我不得不删除一个表，我使用了以下代码。
$("#mydivId table:last-child").remove()

try this. Just added .not(':last-child') which excludes the last element in your collection. So you don't have to remove it.
尝试这个。刚刚添加了 .not(':last-child') ，它排除了集合中的最后一个元素。所以你不必删除它。
$(this).children("a:eq(0)").not(':last-child').append('<img src="'+ (arrowsvar.down[1])
+'" class="' + (arrowsvar.down[0])
+ '" style="border:0;" />'
);
