How to get the content in text in uniapp

UniApp is a cross-platform development tool that allows you to write code once with Vue.js and perform rapid application development on multiple platforms. In the UniApp application, obtaining the content in the text may be a very common requirement, so this article will answer the question of how uniapp obtains the content in the text and help everyone use UniApp better.

1. What is text

In UniApp, text is a basic component used to display text content. Use the text component to display predefined text content directly in the view.

The usage of text is relatively simple. Just use the text tag in the template and then insert the text to be displayed. The sample code is as follows:

<template>
  <view>
    <text>{{ message }}</text>
  </view>
</template>

<script>
  export default {
    data() {
      return {
        message: 'Hello, UniApp!'
      }
    }
  }
</script>

In the above code, we The text component is used to display a string variable named message, whose value is "Hello, UniApp!". In this way we can display this text content on the page.

2. How to get the content in text

In UniApp, to get the content of the text component, you can use the built-in attribute text of the component. This attribute stores the text contained in the text component. content, you only need to call this property in the code.

The following is a sample code. We bind the button click event to a function, in which the text content in the text component is obtained and output to the console.

<template>
  <view>
    <!-- text 组件 -->
    <text>这是文本内容</text>

    <!-- button 组件 -->
    <button type="primary" @click="getText()">获取文本内容</button> 
  </view>
</template>

<script>
  export default {
    methods: {
      getText() {
        console.log(this.$refs.mytext.text);
      }
    }
  }
</script>

In the above code, we bind a function to the click event of the button component. When the button is clicked, the function will be called. This function uses the $refs feature in UniApp to obtain the text content in the text component, and then outputs the content to the console through the console.log function.

It should be noted that when obtaining text content, you must use $refs.mytext.text, where mytext is a reference to the text component and text is a built-in property, otherwise an error will occur.

3. Summary

Through the above code example, we can use this.$refs.mytext.text to obtain the text content in the text component. This method is very simple and has a relatively small amount of code, making it very suitable for most UniApp application scenarios.

Although the usage of the text component is relatively simple, it is also important to understand how to obtain its content. I hope the content of this article can help everyone use UniApp better.
