How to solve the problem that uniapp cannot scroll

With the popularity of smartphones, the demand for mobile applications is also getting higher and higher. Accordingly, many developers have begun to use cross-platform development frameworks, among which uniapp is a popular choice. However, sometimes developers find that they encounter some tricky issues when developing applications using uniapp. One of the common problems is that uniapp applications cannot scroll.

This problem may appear on any page of your uniapp application, including home page, list page, details page, etc. In fact, this problem is not a problem with uniapp itself, but with the components and layout used. Below, we'll explore some common causes and solutions.

Cause 1: Incorrect height setting

When using uniapp to develop applications, many times we need to set the height of components or page elements. If this height is set incorrectly, it may cause the page to fail to scroll. To fix this, we need to make sure the height of our component or page element is set correctly.

Specifically, we can try the following steps:

1. Check whether the height of the container containing the component or page element is set correctly. The height of the container should be set to the minimum value that can cover all contained elements and ensure that it can scroll within the screen.
2. Check whether the height of the component or page element is set correctly. If the height of these elements is set incorrectly, it will also cause the page to become unscrollable. Specifically, the height of these elements should be set to flex-grow:1 or height:100%.
3. If the above two steps cannot solve the problem, you can try to use some layout components provided by uniapp, such as the scroll-view component. The scroll-view component can automatically add scrolling functionality to a component or page element, and the view can be scrolled by setting the scroll-y attribute.

Cause 2: Incorrect component style

Another reason that may cause the uniapp application to fail to scroll is that the component style setting is incorrect. Usually, this problem occurs most often when using some custom components or styles.

In order to solve this problem, we can try the following steps:

1. Check whether the style of the component is correct. You should make sure that no overflow:hidden or other properties that prevent scrolling are set in the style.
2. If our page uses multiple components and one of the components cannot be scrolled, we can try to achieve the purpose of scrolling by adjusting the component hierarchy. Specifically, we can try placing non-scrollable components above components that require scrolling.
3. If the above two steps cannot solve the problem, you can try to manually add scroll events to the component. This can be achieved by adding a touchmove event on the component and acting accordingly.

Conclusion

In general, it is very common to encounter the problem of not being able to scroll when developing applications using uniapp. This problem is usually caused by incorrect height settings for components or page elements or incorrect component styling. We can solve this problem by checking the corresponding settings and making corresponding adjustments. By setting the height and styling of components and page elements correctly, we can ensure that our uniapp apps scroll smoothly and provide users with a better user experience.
