How does uniapp implement the left swipe to delete product function?

With the development of mobile Internet, e-commerce apps are becoming more and more popular, and shopping is becoming more and more convenient. In some e-commerce apps, users can operate products through the sliding interface, such as swiping left to delete products. So, how to swipe left to delete items in uniapp? This article will introduce it to you in detail.

1. First of all, it needs to be made clear that uniapp is a development framework based on Vue.js, so our component implementation will be more Vue.js-based. In Vue.js, we generally use the v-for instruction and arrays for dynamic rendering. Therefore, we can also use a similar method to render our product list in uniapp.
2. Next, we need to implement the function of swiping left to delete products. We can use the movable-view component provided by uni-app. This component can implement dragging effects on the x-axis. In the movable-view component, we need to set the following properties of the movable-view component:

Among them, x is the position of the movable-view component, and the unit is rpx. In our product list, each product should be a movable-view component.

3. In the movable-view component, we need to add a delete button, which should be displayed when the movable-view component slides left beyond a certain distance. In vue.js, we can use the v-if directive to dynamically control the display and hiding of elements, and in uniapp, we can also use conditional rendering to achieve this.
4. When the user clicks the delete button, we need to remove the current product. In Vue.js, we can achieve this through the splice method of the array. Similarly, this method can also be used in uniapp. We can use a custom event to listen for the click event of the delete button and trigger the event in the child component to delete the current product. See the following sample code for specific operations:

         {{item.title}} {{item.price}} {{item.number}}   删除    

Through the above sample code, we can implement the left-swipe to delete product function in uniapp. It should be noted that the product list here is just an example. In actual situations, we need to obtain the product list from the API and render it dynamically. At the same time, we also need to turn the deletion operation into an asynchronous operation, that is, when deleting an item, we need to send a request to the server. Here we only introduce the basic operations in uniapp, and the specific implementation needs further improvement.
