作者：bettyjones
这篇文章主要介绍了element-ui upload组件多文件上传的示例代码，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
之前有一篇写的如何同时传递form表单及upload组件文件，如果有多个upload文件该如何传递呢
上代码
html
<el-form ref="newform" :model="newform" :rules="rules">
<el-form-item prop="expName" label="">
<el-input v-model="newform.expName" placeholder="" style="width:75%">
</el-input>
</el-form-item>
<el-form-item prop="expSn" label="">
<el-input v-model="newform.expSn" placeholder="" style="width:75%">
</el-input>
</el-form-item>
<el-form-item label='' prop="groupName">
<el-select v-model="newform.groupName" placeholder="" style="width:75%" @change="newSelectGroup($event)">
<el-option
v-for="item in groupOptions"
:key="item.groupId"
:label="item.groupName"
:value="item.groupId">
</el-option>
</el-select>
</el-form-item>
<el-form-item label="" prop="subGroupName">
<el-select v-model="newform.subGroupName" placeholder="" style="width:75%" @change="newSelectSubGroup($event)">
<el-option
v-for="item in subGroupOptions"
:key="item.subGroupId"
:label="item.subGroupName"
:value="item.subGroupId">
</el-option>
</el-select>
</el-form-item>
<el-form-item label="" prop="expvmDifficulty">
<el-rate v-model="newform.expvmDifficulty" :max="5" style="line-height: 2;"></el-rate>
</el-form-item>
<el-form-item label="" prop="expvmInstruction">
<el-upload
class="upload-demo"
drag
ref="uploadhtml"
:action="upload_url"
:auto-upload="false"
:before-upload="newHtml"
accept=".html, .htm">
<div class="el-upload__text">将文件拖到此处，或<em>点击上传</em></div>
<div slot="tip" class="el-upload__tip">实验信息上传，只能传(.html/.htm)文件</div>
</el-upload>
</el-form-item>
<el-form-item label="" prop="expvmFiles">
<el-upload
class="upload-demo"
drag
ref="uploadfile"
:action="upload_url"
:auto-upload="false"
:before-upload="newFiles"
multiple>
<div class="el-upload__text">将文件拖到此处，或<em>点击上传</em></div>
<div slot="tip" class="el-upload__tip">实验信息附件上传，只能传(.file)文件</div>
</el-upload>
</el-form-item>
<el-form-item label="" prop="expvmVideo">
<el-upload
class="upload-demo"
drag
ref="uploadvideo"
:action="upload_url"
:auto-upload="false"
:before-upload="newVideo"
accept=".mp4">
<div class="el-upload__text">将文件拖到此处，或<em>点击上传</em></div>
<div slot="tip" class="el-upload__tip">实验视频上传，只能传(.mp4)文件</div>
</el-upload>
</el-form-item>
<el-form-item style="text-align:center">
<el-button type="primary" @click="newSubmitForm()" class="yes-btn">
确 定
</el-button>
<el-button @click="resetForm('newform')">
重 置
</el-button>
</el-form-item>
</el-form>
js
data () {
return {
upload_url: 'aaa', // 随便填一个，但一定要有
uploadForm: new FormData(), // 一个formdata
rules: {}, // 用到的规则
newform: {
expName: '',
groupName: '',
expSn: '',
subGroupName: '',
expvmDifficulty: 1
}
}
}
methods
newSubmitForm () {
this.$refs['newform'].validate((valid) => {
if (valid) {
this.uploadForm.append('expName', this.newform.expName)
this.uploadForm.append('expSn', this.newform.expSn)
this.uploadForm.append('groupId', this.newgroupId)
this.uploadForm.append('subGroupId', this.newsubgroupId)
this.uploadForm.append('expvmDifficulty', this.newform.expvmDifficulty)
newExp(this.uploadForm).then(res => {
if (res.code === 400) {
this.$message.error(res.error)
} else if (res.code === 200) {
this.$message.success('上传成功！')
}
})
this.$refs.uploadhtml.submit() // 提交时触发了before-upload函数
this.$refs.uploadfile.submit()
this.$refs.uploadvideo.submit()
} else {
console.log('error submit!!')
return false
}
})
},
newHtml (file) { // before-upload
this.uploadForm.append('html', file)
return false
},
newFiles (file) {
this.uploadForm.append('file[]', file)
return false
},
newVideo (file) {
this.uploadForm.append('video', file)
return false
}
newExp函数是作为一个前后端交互的函数
export function newExp (data) {
return axios({
method: 'post', // 方式一定是post
url: '你的后台接收函数路径',
timeout: 20000,
data: data // 参数需要是单一的formData形式
})
}
PHP代码，后台接收
public function newExp() {
$param = $this->request->post(); // 获取页面表单传值
$files = $this->request->file(); // 接收到的文件
}
注意
this.uploadForm.append('file[]', file)
这里是接收多文件一定要是数组形式的file[]
