How to solve the problem of sliding deletion on the mobile side in Vue development

With the popularity of mobile devices, more and more applications have begun to support mobile use, and the sliding deletion function has also become a part of users' daily use. An important interaction requirement. In Vue development, how to flexibly implement the sliding delete function on the mobile terminal has become one of the focuses of developers. This article will introduce a method to solve the problem of sliding deletion on the mobile terminal. I hope it will be helpful to Vue developers.

First of all, we need to clarify the implementation principle of sliding deletion. On the mobile side, sliding deletion usually monitors touch events and determines whether the user wants to delete an element based on the sliding direction and distance of the finger. A common implementation method is to use the transform attribute of CSS to displace elements, and use transition effects to make the deletion action smoother.

In the development of Vue, we can use Vue's custom instructions to implement the sliding delete function. First, we need to listen to the touch events of the mobile device and obtain the user's sliding direction and distance. Then, based on this data, decide whether to display the delete button and achieve the sliding delete effect.

Next, let’s implement this idea in detail. First, create a custom directive in the Vue project and name it v-swipe-delete. In this directive, we can register some listeners for touch events, such as touchstart, touchmove and touchend. Through these events, we can obtain the position information of the finger on the screen.

Next, in the v-swipe-delete command, we can determine whether the user wants to delete an element based on the sliding direction of the finger. For example, if the finger slides to the right, we can think that the user wants to delete an element. At this time, we can set the transform attribute of the element to a negative value to make it slide to the left and hide the delete button. Conversely, if the finger slides to the left, we can set the element's transform property to a positive value, causing it to slide to the right and display the delete button.

In addition, we can also add some transition effects to increase the smoothness of sliding deletion. For example, in the CSS style of an element, we can add the transition attribute to create a transition effect from hiding to showing or from showing to hiding.

Finally, in order to implement the delete function when clicking the delete button, we can bind a click event to the delete button. In the click event, we can use Vue's data loop binding mechanism to remove the elements that need to be deleted from the data list.

To sum up, the idea of solving the problem of sliding deletion on the mobile terminal is as follows: First, create a custom instruction in the Vue project to listen to touch events to obtain finger position information. Then, based on the sliding direction and distance of the finger, it is judged whether the user wants to delete an element. According to the judgment result, the position attribute of the element is changed to achieve the effect of sliding deletion. Finally, bind the click event to the delete button to implement the delete function.

Through the above steps, we can easily implement the sliding delete function on the mobile side in Vue development. This method is not only flexible and scalable, but also has a smooth effect and meets the user's interaction needs. I hope the introduction in this article can be helpful to Vue developers when solving the problem of sliding deletion on the mobile terminal.
