上传完成
1.HTML
<div class="rz-picter">
<img :src="avatar" class="img-avatar">
<input type="file" name="avatar" id="uppic" accept="image/gif,image/jpeg,image/jpg,image/png" @change="changeImage($event)" ref="avatarInput" class="uppic">
</div>
2.js
data() {
return {
avatar: require('../assets/jia.jpg'), //站位图
}
},
图片一定要以require 的方式引入 这里的图片仅用来美化 并不是上传的图片
3.js 写方法
changeImage(e) {
var file = e.target.files[0]
var reader = new FileReader()
var that = this
reader.readAsDataURL(file)
reader.onload = function(e) {
that.avatar = this.result
}
},
就这么几段代码一个上传功能就写好了
附上写此功能所有代码：
<template>
<div>
<div class="color-black" style="text-align: center;margin-top: 0.4rem;">请上传本人名片照片</div>
<div class="rz-picter">
<img :src="avatar" class="img-avatar">
<input type="file" name="avatar" id="uppic" accept="image/gif,image/jpeg,image/jpg,image/png" @change="changeImage($event)" ref="avatarInput" class="uppic">
</div>
<div class="yzbtn">立即认证</div>
</div>
</template>
<script>
import { Toast } from 'mint-ui'
export default {
name: 'renzheng',
data() {
return {
avatar: require('../assets/jia.jpg'),
}
},
methods: {
// 判断如果没有图片不能上传
if(document.getElementById('uppic').value.length == '') {
Toast('请上传图片');
return;
}
},
changeImage(e) {
var file = e.target.files[0]
var reader = new FileReader()
var that = this
reader.readAsDataURL(file)
reader.onload = function(e) {
that.avatar = this.result
}
},
},
}
</script>
<style>

.img-avatar {

/*立即验证*/
.yzbtn {

},
reader: new FileReader(),
}
},
methods: {
add_img(event){
let img1=event.target.files[0];
let type=img1.type;//文件的类型，判断是否是图片
let size=img1.size;//文件的大小，判断图片的大小
if(this.imgData.accept.indexOf(type) == -1){
Toast('请选择我们支持的图片格式！');
return false;
}
if(size>3145728){
Toast('请选择3M以内的图片！');
return false;
}
this.reader.readAsDataURL(img1);
var that=this;
this.reader.onloadend=function(){
that.imgs.push(this.result);
}
},
submitBtn() {
console.log(this.imgs);
// 此处是上传图片的接口，上传的图片为base64格式且为一个数组，需要后台接受处理
},
},
}
</script>
