关于uniapp:uniapp点击上传图片后清除原来的图片数据

执行步骤：
点击“上传图片”按钮弹出弹窗，抉择图片点击“确定”图片上传胜利后弹窗敞开，再点击上传图片会发现弹窗会保留有上次选中图片的数据。
开发要求：
图片上传胜利后默认革除上一次选中上传的图片数据。

解决办法：

<view class="pop-up1" @click="rule1=true"> 弹窗 1 </view>
    <view class="sure_btn" @click="formData.type = 2;showOne()">
        <p> 上传图片 </p>
    </view>
</view>


<!-- 弹窗 -->
<view class="boxBm test_pop" v-if="isLower">
    <view class="box2 share-state">
        <image class="img_close" @click="closePop" src="../../../static/img/koreaActive/close.png" mode=""></image>
        <view class="addImg">
            <image class=""@click="addImg(),imgItem=true"src="../../../static/img/japanActive/upload.png"mode=""></image>
        </view>
        <textarea class="active_text" maxlength="1000" @input="getText" v-model="formData.remarks" placeholder="您尊贵的意见和倡议......" />
        <button type="default" @click='uploadImage()'> 確定 </button>
        <view class="Img_box" v-if="imgItem" v-for="(item,index) in imgList" :key="index">
