<img :src="variable"> // just use : in front of an attribute and it will consider as v-bind
<img v-bind:src="variable"> // or you directly use v-bind, less commonly used
<img :src="'static string'"> // no point doing this, but just a reference of how it works
当您使用组合API时,您必须先导入ref等函数。
<template>
<img :src="data">
<img v-bind:src="data">
<img :src="getimg()">
</template>
<script setup>
import { ref } from 'vue'
const data = ref("./assets/4168-376.png") // prefer const over var cus this variable will never be reassigned
function getimg() {
// why are you using data1.value tho? It should be data.value
// also i don't think 'require' is needed here
return require(data1.value) // i just copy paste from your code
}
</script>
根据您的代码,您正在使用 Vue3 Composition API。您的代码中缺少一些内容,这些内容可能无法让您的应用正常运行。
ref等函数。<template> <img :src="data"> <img v-bind:src="data"> <img :src="getimg()"> </template> <script setup> import { ref } from 'vue' const data = ref("./assets/4168-376.png") // prefer const over var cus this variable will never be reassigned function getimg() { // why are you using data1.value tho? It should be data.value // also i don't think 'require' is needed here return require(data1.value) // i just copy paste from your code } </script>额外:当处理不需要参数的值时,通常使用
计算会更好。请参阅 Vue 计算属性<template> <img :src="data"> <img v-bind:src="data"> <img :src="getImg"> </template> <script setup> import { ref, computed } from 'vue' // import it first const data = ref("./assets/4168-376.png") const getImg = computed(() => { return data.value })
