仿照el-upload 封装自己的上传控件（el-upload 移动端无法吊起相机）

input选择图片的那个选择在h5的时候在去年下半年突然无法无法出现唤醒相机的选项  不知道出现的原因 

发现el-upload作为h5的时候无法吊起相机 

又因为需要对服务端地址图片进行回显（处于编辑功能的情况下 非新增 新增el-upload 可以实现回显）  两个功能el-upload都不能很好的支持 所以自己仿照el-upload 做了上传组件的封装

具体代码如下图所示

<template>
    <div style="display: flex; height: 100%;">
        <div v-for="(item,idx) in httpLits" :key="item" class="listitem">
            <div class="inner">
                <img :src="`${item}`">
                <div class="delete" @click="delimg(idx)">
                    <i class="el-icon-delete"></i>
                </div>
            </div>
        </div>
        <div class="inputbox" v-if="httpLits.length !== 5" :class="httpLits.length > 0 ? 'listitem' : ''">
            <i class="ri-camera-fill"></i>
            <span>{{ httpLits.length === 0 ? '添加图片' : `还可添加${5 - httpLits.length}张`
            }}</span>
            <input v-if="inputshow" type="file" name="image" :accept="'image/*'" @change="onchangeImgFun"
                style="position: absolute; width: 100%;height: 100%;opacity: 0;" />
        </div>
    </div>
</template>

    },
    methods: {
        onchangeImgFun(e) {
            console.log(e.target.files)
            var file = e.target.files[0];
            this.inputshow = false
            let formData = new FormData()
            formData.append('image', file)
            axios({
                method: 'post',
                url: `xxxx`,
                data: formData
            },

            ).then(res => {
                this.httpLits.push(res.data.data.image)
                this.$emit('input', this.httpLits)
                this.inputshow = true
            }).catch(() => {
                alert('上传失败')
            })
        },
        // 删除图片
        delimg(idx) {
            this.httpLits.splice(idx, 1)
