jquery - JQuery toggleClass 不适用于动态数据

问题描述

从我的代码中，当我单击共享图标时，它会弹出并显示一些社交媒体共享图标。仅当单击共享图标然后单击交叉（X）图标时，切换才有效。如果我单击共享图标并单击页面上的其他位置，然后单击交叉（X）图标切换不起作用。谁能建议如何解决这个问题。

var courseslist = "";
for(var i=0; i<3;i++){

courseslist += "<div class='card__share'>";
courseslist += "<div class='card__social'>";
courseslist += "<a class='share-icon facebook' href='#'><span class='fa fa-facebook'></span></a>";
courseslist += "<a class='share-icon twitter' href='#'><span class='fa fa-twitter'></span></a>";
courseslist += "<a class='share-icon googleplus' href='#'><span class='fa fa-google-plus'></span></a>";
courseslist += "</div>";
courseslist += "<a id='share' class='share-toggle share-icon' href='#'></a>";

解决方案

问题是 z-index 不适用于position: static. 您需要将共享切换相对定位，然后才能正常工作。

.share-toggle {
  position:relative;
  z-index: 2;
}
