  • 通过input标签来上传文件

  • 单文件上传

  1. <input type="file" @change="handleFile">
  2. <!-- 存放图片 -->
  3. <img v-if="curImgUrl!=''" :src="baseImg+curImgUrl" alt="" srcset="" style="width:200px;height:auto;">
  4. <button @click="toUpload">上传</button>
  1. const handleFile = ()=>{
  2. // console.log(window.event.target.files);
  3. let filePaths = window.event.target.files[0];
  4. let obj = {file:filePaths};
  5. fileUrl.value = obj;
  6. }
  7. const toUpload = ()=>{
  8. // 创建一个表单数据
  9. var data = new FormData();
  10. data.append("file",fileUrl.value.file);
  11. uploads(data).then((res)=>{
  12. console.log(res);
  13. alert(res.message);
  14. if(res.code==1){
  15. curImgUrl.value = res.data.img;
  16. }
  17. })
  18. }

  • 多文件上传
  1. <!-- 多文件上传 -->
  2. <input type="file" id="back" ref="backfile" multiple @change="handleFile2" />
  3. <div class="btCont">

  3. //清空原有缩略图
  4. if (filePaths.length === 0) {
  5. //未选择,则返回
  6. return
  7. } else {
  8. //清空数组中原有图片
  9. selFiles.value.length = 0;
  10. }
  11. //把新选中的图片加入数组
  12. for( var i=0;i<filePaths.length; i++ ){
  13. let file = filePaths[i];
  14. let one = {
  15. file:file,
  16. }
  17. selFiles.value.push(one);
  18. }
  19. }
  20. const toUpload2 = ()=>{
  21. // 创建一个表单数据
  22. var data = new FormData();
  23. //遍历文件,添加到form
  24. for( var i=0;i<selFiles.value.length; i++ ){
  25. let fileOne = selFiles.value[i].file;
  26. data.append("file[]",fileOne);
  27. }
