本文介绍了vue+node实现图片上传及预览的示例方法，分享给大家，具体如下：
先上效果图
上代码
html部分主要是借助了weui的样式
<template>
<div>
<myheader :title="'发布动态'">
<i class="iconfont icon-fanhui1 left" slot="left" @click="goback"></i>
</myheader>
<div class="upload">
<div v-if="userInfo._id">
<!--图片上传-->
<div class="weui-gallery" id="gallery">
<span class="weui-gallery__img" id="galleryImg"></span>
<div class="weui-gallery__opr">
<a href="javascript:" rel="external nofollow" class="weui-gallery__del">
<i class="weui-icon-delete weui-icon_gallery-delete"></i>
</a>
</div>
</div>
<div class="weui-cells weui-cells_form">
<div class="weui-cell">
<div class="weui-cell__bd">
<textarea class="weui-textarea" v-model="content" placeholder="你想说啥" rows="3"></textarea>
</div>
</div>
<div class="weui-cell">
<div class="weui-cell__bd">
<div class="weui-uploader">
<div class="weui-uploader__bd">
<ul class="weui-uploader__files" id="uploaderFiles">
<li ref="files" class="weui-uploader__file" v-for="(image,index) in images" :key="index"
:style="'backgroundImage:url(' + image +' )'"><span @click="deleteimg(index)" class="x">×</span></li>
</ul>
<div v-show="images.length < maxCount" class="weui-uploader__input-box">
<input @change="change" id="uploaderInput" class="weui-uploader__input " type="file"
multiple accept="image/*">
</div>
</div>
</div>
</div>
</div>
</div>
<a class="weui-btn weui-btn_primary btn-put" style="margin: 20px " @click.prevent.once="put">发送</a>
</div>
<unlogin v-else> </unlogin>
</div>
</div>
</template>重点部分在于
<ul class="weui-uploader__files" id="uploaderFiles">
<li ref="files" class="weui-uploader__file" v-for="(image,index) in images" :key="index"
:style="'backgroundImage:url(' + image +' )'"><span @click="deleteimg(index)" class="x">×</span></li>
</ul>
<div v-show="!this.$refs.files||this.$refs.files.length < maxCount" class="weui-uploader__input-box">
<input @change="change" id="uploaderInput" class="weui-uploader__input" type="file"
