<script setup>

import { UploaderComponent as EjsUploader } from '@syncfusion/ej2-vue-inputs';

const path = {
  saveUrl: 'https://services.syncfusion.com/vue/production/api/FileUploader/Save',
  removeUrl: 'https://services.syncfusion.com/vue/production/api/FileUploader/Remove'
}

const onSelect = (args) => {
  if (initial) { initial = false; return; }
  args.isModified = true;
  let oldFiles = uploadObj.value.ej2Instances.getFilesData();
  let filesData = args.filesData.concat(oldFiles);
  let modifiedData = sortFileList(filesData);
  args.modifiedFilesData = modifiedData;
};

const sortFileList = (filesData) => {
  let files = filesData;
  let fileNames = [];
  for (let i = 0; i < files.length; i++) {
    fileNames.push(files[i].name);
  }
  let sortedFileNames = fileNames.sort();
  let sortedFilesData = [];
  for (let name of sortedFileNames) {
    for (let i = 0; i < files.length; i++) {
      if (name === files[i].name) {
        sortedFilesData.push(files[i]);
      }
    }
  }
  return sortedFilesData;
};
