我有带有图标的按钮，我想在将鼠标悬停在该图标上时附加工具提示。

但它不起作用，请参见下面的示例：

$(document).ready(function() {
  $("#primaryTextButton").kendoButton({
    icon: "filter-clear"
  });
  $("#textButton").kendoButton({
    icon: "filter-clear"
  });

  var tooltip = $("#example").kendoTooltip({
    filter: "button[tooltip] > span",
    position: "top",
    content: function(e) {
      var target = e.target;
      if (target.parent().attr("tooltip")) {
        return target.parent().attr("tooltip");
      } else {
        return null;
      }

    }
  });
});
.demo-section p {
  margin: 0 0 30px;
  line-height: 50px;
}

.demo-section p .k-button {
  margin: 0 10px 0 0;
}

.k-primary {
  min-width: 150px;
}

使用 HTML 按钮有效。带有.k-button类的东西。

请参见下面的带有 HTML 按钮的工作示例：

您试图span在图标实际存在之前将其作为目标元素，因此您的过滤器失败了。

如果您将过滤器更改为此，您仍然可以在按钮悬停时显示工具提示：

filter: "button[tooltip]"

显然，这假设您不需要仅在 ICON 悬停时显示工具提示，但这取决于您的要求。:)
