You can sort the selected files in uploader component by using the selected event. Refer to the following example.
// initialize Uploader component
var uploadObject = new ej.inputs.Uploader({
asyncSettings: {
saveUrl: 'https://ej2.syncfusion.com/services/api/uploadbox/Save',
removeUrl: 'https://ej2.syncfusion.com/services/api/uploadbox/Remove'
},
selected: onSelect
});
uploadObject.appendTo('#fileupload');
function onSelect(args) {
if (initial) { initial = false; return; }
args.isModified = true;
var oldFiles = uploadObj.getFilesData();
var filesData = args.filesData.concat(oldFiles);
var modifiedData = sortFileList(filesData);
args.modifiedFilesData = modifiedData;
}
function sortFileList(filesData) {
var files = filesData;
var fileNames = [];
for (var i = 0; i < files.length; i++) {
fileNames.push(files[i].name);
}
var sortedFileNames = fileNames.sort();
var sortedFilesData = [];
var index = 0;
for (var i = 0; i < sortedFileNames.length; i++) {
var name = sortedFileNames[i];
for (let i = 0; i < files.length; i++) {
if (name === files[i].name) {
sortedFilesData.push(files[i]);
}
}
}
return sortedFilesData;
