How to set src in vue

Vue is a popular JavaScript framework that makes it easy to build modern web applications. In Vue, you can use the src attribute to load images, audio files, or video files. Setting the src attribute allows Vue to bring external resources into your application. In this article, we will take a deeper look at how to set up src using Vue.

1. Use v-bind directive to set src

You can use v-bind directive to set src attribute in Vue template. The v-bind directive allows you to bind JavaScript expressions with HTML attributes.

For example, you can set the src attribute of an image in a Vue template using the following code:

<img v-bind:src="imagePath">

In this case, you need to store the image path in the JavaScript variable imagePath. You can define the imagePath variable in the data attribute of the Vue component as follows:

<script>
  export default {
    data() {
      return {
        imagePath: '/path/to/image.jpg'
      }
    }
  }
</script>

In this code, the data attribute of the Vue component contains a variable called imagePath, which stores the path to the image. In the Vue template, we bind this variable with the image's src attribute using the v-bind directive.

2. Set the src attribute directly

You can also set the src attribute directly without using the v-bind directive. This may be more convenient for some developers because you don't need to store the image path in a variable.

For example, you can use the following code to set the src attribute of the image in the Vue template:

<img src="/path/to/image.jpg">

In this code, we set the src attribute of the image directly without using the v-bind directive .

3. Use computed properties to set src

Vue also provides computed properties for dynamically calculating the values ​​of other properties. You can set the src attribute of an image using computed properties.

For example, you can set the src property of an image in a Vue template using the following code:

<template>
  <div>
    <img v-bind:src="imageSrc">
  </div>
</template>

<script>
  export default {
    data() {
      return {
        imageUrl: '/path/to/image.jpg'
      }
    },
    computed: {
      imageSrc() {
        return this.imageUrl + '?random=' + Math.random()
      }
    }
  }
</script>

In this case, we define a computed property called imageSrc, which is dynamically calculated The src attribute of the image. This allows you to dynamically update the src attribute, for example by adding a random number to the URL to refresh the cache.

Summary

Setting the src attribute in Vue is very simple. You can use the v-bind directive, set properties directly or use computed properties. This allows you to easily load images, audio files or video files and makes Vue applications more flexible and scalable.
