Achieve File Upload Programmatically in JavaScript (ES5) Uploader control

08 May 2023 / 1 minute to read

You can upload a file programmatically using the upload method. Get the selected files data from the getFilesData public method in uploader.

The upload method behaves differently based on its arguments.

  • If this method receives any files as arguments, those files only start to upload.
  • If it has no argument, all the selected files start to upload.

//Initialize the control by preload files
var uploadObj = new ej.inputs.Uploader({

        removeUrl: 'https://ej2.syncfusion.com/services/api/uploadbox/Remove'
    }
});
uploadObj.appendTo('#fileupload');

document.getElementById('first').onclick = function (args) {
    uploadObj.upload(uploadObj.getFilesData()[0]);
};

document.getElementById('full').onclick = function (args) {
    uploadObj.upload(uploadObj.getFilesData());
};
