How to solve the problem of mobile scroll penetration in Vue development

The mobile scroll penetration problem means that on mobile devices, when scrolling an element, the page behind it will also be scrolled. This problem is often encountered in mobile development, especially when using the Vue framework to develop mobile applications. In order to solve this problem, we need to process the scroll event. Below we will introduce a method to solve the scroll penetration problem on the mobile terminal.

First of all, we can define a data attribute in the Vue instance to control the solution to the scroll penetration problem. We can name this propertyisScrollable. WhenisScrollableis true, the page can be scrolled, when it is false, the page cannot be scrolled.

Next, in the Vue template, we need to bind a scrolling event to the element that needs to be scrolled, and determine the value ofisScrollablein the event handling function. IfisScrollableis false, we can prevent the default behavior of the event to solve the scroll penetration problem.

The specific implementation method is as follows:

In this example, we bind a scroll event to the element that needs to be scrolled, and usepreventDefault( )method to prevent the default behavior of scroll events. In this way, whenisScrollableis false, the page cannot be scrolled, thereby solving the mobile terminal scroll penetration problem.

In order to better implement this solution, we can combine Vue's life cycle hook function to dynamically control the value ofisScrollable. For example, we can setisScrollableto true in Vue'smountedhook function, indicating that the page can be scrolled; in Vue'sbeforeDestroyhook function, setisScrollableSet to false, indicating that the page cannot be scrolled.

The following is an improved code example:

Through the above method, we can easily solve the mobile terminal scroll penetration problem and improve the user experience in Vue development.

In summary, the key to solving the scroll penetration problem on mobile is to control scrolling events and prevent default behavior. This problem can be solved well by defining a property in the Vue instance to control the default behavior of scroll events. At the same time, more flexible scrolling control can be achieved by dynamically setting the value of this property in the appropriate life cycle hook function.
