data:image/png；base64,拼接字符串，无法展示图片

data:image/png;base64,拼接字符串，无法展示图片

错误代码

// vue3
const normalImg = computed(() => store.getters.SignalImg);
const img = computed(() => {
  returnreturn "data:image/png;base64," + normalImg;
});

展示图片

正确代码

const normalImg = computed(() => {
  return `data:image/png;base64,${store.getters.SignalImg.replace(/[\r\n]/g,"")}`;
});

无法上传同一张图片

// 解决方案
<template>
	<div>
		<input 
			id="inputImg" 
			src="normalImg"
			 @change="onChange($event)"
	</div>
</template>
<script setup>
	const onChange = (e) => {
		 document.querySelector('#""inputImg').value = ''
	}
</script>
