+在 JavaScript 中，与触摸事件对应的鼠标事件分别是：
+
+- `touchstart` 对应 `mousedown`
+- `touchend` 对应 `mouseup`
+
+因此，将你的代码中的触摸事件改为鼠标事件后，代码可以改写为：
+
+ 
+ 1.
+```javascript
+// 监听 mousedown 事件
+container.addEventListener('mousedown', function() {
+  hideDataLabels(chart);
+});
+
+// 监听 mouseup 事件
+container.addEventListener('mouseup', function() {
+  showDataLabels(chart);
+});
+```
+
+或者也可以改成为:
+ 
+ 2.
+ ```javascript
+ // 监听 mouseenter 事件
+ container.addEventListener('mouseenter', function() {
+   hideDataLabels(chart);
+ });
+
+ // 监听 mouseleave 事件
+ container.addEventListener('mouseleave', function() {
+   showDataLabels(chart);
+ });
+ ```
