1. 编辑已上传的图片

this.picsList.push({url: picsURL})

2.上传图片后隐藏上传框

upload
    action="none"
    :auto-upload="false"
    list-type="picture-card"
    :on-change="picsChange"
    :on-remove="picsRemove"
    :limit="1"
    :file-list="picsList"
    :class="noneStyle:picsList.length===0,picStyle:picsList.length === 1}">
        


picsChange(file, filelist){
    ...
    this.picsList = filelist
    ...
},
picsRemove(file, filelist) {
    this.picsList=[]
},
