In recent years, the user experience of mobile applications has become an area that designers and developers pay more and more attention to. Using a smooth, easy-to-use interface becomes the key to an app winning over users. As part of the user experience, sliding to delete can make application operations more convenient and allow users to find the content they need more quickly, so it is often used in various applications.

This article will introduce the method of implementing side sliding deletion in uniapp.

1. Background

uniapp is a cross-platform development tool based on the Vue.js framework. By using uniapp, developers can easily develop functions that can be used on multiple platforms (including iOS, Android , H5, etc.).

User experience is crucial when developing mobile applications. Side-swipe deletion is a user-friendly method and can usually be used for operations such as deleting list items. Therefore, implementing side-swipe deletion in a mobile application can make the application easier to use and improve user satisfaction.

2. Implementation method

In uniapp, you can use the swipeout component to implement the side-swipe deletion function. The Swipeout component is a component based on the Vue.js framework that can be used to create list items with sliding deletion functionality. The following will introduce how to implement the swipeout component in uniapp.

1. Create a list

First, you need to create a list, which can be a static list or a dynamic list that gets data from the API. For example, you can create a static list that contains some sample data.

<template>
  <view>
    <view>
      <text>{{ item.title }}</text>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      list: [
        { title: &#39;列表项1&#39; },
        { title: &#39;列表项2&#39; },
        { title: &#39;列表项3&#39; },
        { title: &#39;列表项4&#39; },
        { title: &#39;列表项5&#39; }
      ]
    };
  }
};
</script>

2. Add the swipeout component

Next, add the swipeout component on each list item. In order for users to see the effect of sliding to delete, a button or icon needs to be added to the component.

<template>
  <view>
    <swipeout>
      <view>
        <text>{{ item.title }}</text>
      </view>
      <view>
        <text>删除</text>
      </view>
    </swipeout>
  </view>
</template>

<script>
export default {
  data() {
    return {
      list: [
        { title: &#39;列表项1&#39; },
        { title: &#39;列表项2&#39; },
        { title: &#39;列表项3&#39; },
        { title: &#39;列表项4&#39; },
        { title: &#39;列表项5&#39; }
      ]
    };
  }
};
</script>

<style>
.right {
  width: 100px;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
}
</style>

In the above code, the content slot in the swipeout component is used to specify the content of the list item, and the action slot is used to specify the button that floats out when sliding to the left. When reusing the swipeout component, the autoClose attribute can specify whether the current side slide item will be automatically closed when the next side slide item is opened.

3. Add a delete method

Finally, add a delete method that can delete the corresponding list item from the data source when the delete button is clicked. For example, add the delete method in the above sample code as follows:

<template>
  <view>
    <swipeout>
      <view>
        <text>{{ item.title }}</text>
      </view>
      <view>
        <text>删除</text>
      </view>
    </swipeout>
  </view>
</template>

<script>
export default {
  data() {
    return {
      list: [
        { title: &#39;列表项1&#39; },
        { title: &#39;列表项2&#39; },
        { title: &#39;列表项3&#39; },
        { title: &#39;列表项4&#39; },
        { title: &#39;列表项5&#39; }
      ]
    };
  },
  methods: {
    removeItem(index) {
      this.list.splice(index, 1);
    }
  }
};
</script>

<style>
.right {
  width: 100px;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
}
</style>

In the above code, a method named removeItem is added to delete the list item at the specified index from the list array. Added a @click event on the delete button to trigger the removeItem method.

After completing the above operations, the slide-to-delete function can be successfully applied in the application.

3. Summary

It is very simple to implement the side-swipe deletion function in uniapp. You only need to use the swipeout component. By developing the side-swipe deletion function, the application can be made easier to use and the user experience can be improved. This is a necessary step to gain user trust and favor for your app.
