What should I do if uniapp search does not close?

With the continuous development of mobile applications, many developers have begun to use cross-platform development frameworks, such as UniApp, to build applications. UniApp can build native apps on both iOS and Android, reducing the workload of writing and maintaining code for different platforms. However, sometimes we encounter some strange issues, such as the search box not closing automatically when searching in the app. This problem may seem tricky, but it actually has some relatively simple solutions.

First of all, we need to understand the principle of Uniapp search. Search in Uniapp relies on the input component. When we enter content in the input component, it will trigger an input event. In this event, we can get the content in the input box and then use this content to search. However, after we finish typing and click the search button, the input boxes should automatically close, but in some cases, they may not close, causing the search box to continue to be displayed on the page, which is obviously undesirable.

So, how to solve this problem? Here are several solutions, you can choose one of them based on your actual needs, or adjust it to suit your needs.

Method 1: Use Vue's ref attribute

Add the ref attribute in the input component, then use $refs in the click event of the search button to access the input component and change the value of the input component Empty. The code is as follows:

<template>
  <input>
  <button>搜索</button>
</template>
<script>
  export default {
    data() {
      return {
        searchValue: &#39;&#39;
      }
    },
    methods: {
      handleSearch() {
        // 引用 input 元素
        this.searchInput.searchValue = &#39;&#39;
        // 进行搜索操作
      }
    }
  }
</script>

The advantage of this method is: it is very simple and only requires adding one line of code. However, this method may be less stable if your search box is a pop-up.

Method 2: Use the v-if attribute

In the click event of the search button, add a v-if attribute to control the display and hiding of the input box. When the search button is clicked, we hide the input box by changing the value of v-if. The code is as follows:

<template>
  <div>
    <input>
    <button>搜索</button>
  </div>
</template>
<script>
  export default {
    data() {
      return {
        showInput: true,
        searchValue: &#39;&#39;
      }
    },
    methods: {
      handleSearch() {
        this.showInput = false
        // 进行搜索操作
      }
    }
  }
</script>

The advantage of this method is that it is very stable and the search box will be automatically closed when the search is completed. However, the code is cumbersome and additional logic code needs to be added.

Method 3: Use the blur event of the input component

When the input box loses focus, we can use the blur event to close the input box. Add a blur event to the input component. When the input box loses focus, we can close the input box. The code is as follows:

<template>
  <input>
  <button>搜索</button>
</template>
<script>
  export default {
    data() {
      return {
        searchValue: &#39;&#39;
      }
    },
    methods: {
      handleBlur() {
        // 进行搜索操作
        // 关闭输入框
      },
      handleSearch() {
        // 进行搜索操作
        // 关闭输入框
      }
    }
  }
</script>

The advantage of this method is that it is very stable and can automatically close the input box when it loses focus. However, we need to add additional logic code and cannot solve the problem of automatically closing the input box when the search is completed.

Summary:

When implementing the search function in Uniapp, there may be a problem that the search box does not close automatically, but this is not impossible to solve. We can choose different solutions according to our needs. For example, use the ref attribute, v-if attribute, or the blur event of the input component to solve the problem. Different solutions have their pros and cons, depending on your actual needs.
