页面使用
只上传文件的形式
<template>
<div class="upload">
<Button text="批量导入" background="#36395C" color="#fff" :icon="true" @click.native="handleExportBtn" />
// ...
<ImportData
:showDialogVisible="exportVisible"
:downloadDemoUrl="downloadStandardSpeech"
:uploadFileUrl="uploadFileUrl"
@dialogVisible="closeVisible"
/>
</div>
</template>
<script>
import ImportData from '@/views/components/ImportData.vue'
export default {
name: "index",
components: {
ImportData,
},
data() {
return {
// 导入弹框显示和隐藏
exportVisible: false,
downloadStandardSpeech: `${process.env.VUE_APP_EXPORTDEOM_API}/fileResources/templates_standardSpeech.xlsx`, // 模板下载文件地址,
uploadFileUrl: 'http://10.0.0.10:3000/v1/inspectionSpeechArt/importExcel' // 可以写在配置文件中
};
},
computed: {
userAccountID() {
return this.$store.state.user.userAccountID;
},
},
// created() {
// this.getDataList();
// this.getCheckType();
// },
activated() {
this.getDataList();
this.getCheckType();
},
watch:{},
methods: {
// 导入
handleExportBtn(){
this.exportVisible = true
},
// 关闭导入
closeVisible(){
this.exportVisible = false
// 刷新列表等操作
},
},
};
</script>
<style lang="scss" scoped>
</style>
上传文件和其他必传参数的形式
<template>
<div class="upload">
<Button text="批量导入" background="#36395C" color="#fff" :icon="true" @click.native="handleExportBtn" />
// ...
<ImportData
:showDialogVisible="exportVisible"
:downloadDemoUrl="downloadStandardSpeech"
:uploadFileUrl="uploadFileUrl"
:otherUploadData="otherUploadData"
@dialogVisible="closeVisible"
/>
</div>
</template>
<script>
import ImportData from '@/views/components/ImportData.vue'
export default {
name: "index",
components: {
ImportData,
},
data() {
return {
// 导入弹框显示和隐藏
exportVisible: false,
downloadStandardSpeech: `${process.env.VUE_APP_EXPORTDEOM_API}/fileResources/templates_standardSpeech.xlsx`, // 模板下载文件地址,
uploadFileUrl: 'http://10.0.0.10:3000/v1/inspectionSpeechArt/importExcel',
otherUploadData: {},
};
},
computed: {
userAccountID() {
return this.$store.state.user.userAccountID;
},
},
// created() {
// this.getDataList();
// this.getCheckType();
// this.otherUploadData = { key : 'value' };
// },
activated() {
this.getDataList();
this.getCheckType();
this.otherUploadData = { key : 'value' };
},
watch:{},
methods: {
// 导入
handleExportBtn(){
this.exportVisible = true
},
// 关闭导入
closeVisible(){
this.exportVisible = false
// 刷新列表等操作
},
},
};
</script>
<style lang="scss" scoped>
</style>
效果如下
