C# 发生回发时，特定的JQuery效果将停止工作

我有一个动态创建的

，我正在尝试使用

FadeIn

FadeOut

效果。但是，当回发发生时，这些Jquery效果将停止工作。加载页面时，一切正常，但如果发生回发，它们将停止

动态创建DIV

如果替换元素，事件处理程序将不再绑定到新的元素（因为它们是全新的、独立的元素），即使它们与最初执行代码绑定它们时的条件相匹配。您需要使用：

在这种情况下，您应该使用“on”，而不是将事件绑定到对象

$(document).on({
     mouseenter: function(e) {
         $(this).find(".botaoExcluir").fadeIn();
     },
     mouseleave: function(e) {
         $(this).find(".botaoExcluir").fadeOut();
     }
}, '.linhaImovel');
