取消上传或关闭弹窗再打开后,上传相同图片无法成功
this.$refs.file.value ='' // 清空上传文件中遗留文件
选择后得到base64码,可以预览图片
// 选择文件
fileChange(e) {
this.form.file = e.target.files[0];
this.form.name = this.form.file.name
// 展示成图片Base64 格式
var reader = new FileReader()
reader.readAsDataURL(this.form.file)
reader.onload = function (result) {
console.log(result)
this.img = result.target.result
}
},
在页面中预览
<img :src=" 'data:image/png;base64,' + this.img">
但是因为现在上传的是excel所以无法预览。文章来源:https://www.toymoban.com/news/detail-640939.html
