preventDefault 禁止根级div默认事件子级div滚动条滚动无效怎么解决？

我写了一个页面上下滑动翻页，当我手指放到中间有内容的那个div范围内时，禁止了touchmove事件，用的是{

                    //阻止默认事件发生
                    e.preventDefault()
                    //阻止冒泡事件发生
                    e.stopPropagation()
                    e.nativeEvent.stopImmediatePropagation();}

但是中间那个div（有内容的那个）的滚动条就无法在手机上滚动了，在PC端电脑上可以滚动，请问大神，这个怎么解决？代码如下：

e.nativeEvent.stopImmediatePropagation();方法是防止对事件流中当前节点中和所有后续节点中的事件侦听器进行处理。此方法会立即生效，并且会影响当前节点中的事件侦听器。而这里只需要对当前事件侦听器进行处理，所以这里不需要，注释掉即可，还有绑定需要滚动的那个div的对象，绑定个touchmove事件中e.stopPropagation()防止冒泡即可。
