How to upload programmatically in EJ2 JavaScript File Upload

08 Sep 20265 minutes to read

You can upload a file programmatically using the upload method. Use the getFilesData public method to retrieve the selected files from the Uploader. The file list returned by getFilesData can be passed to the upload method to trigger an upload for specific files without user interaction.

The upload method accepts an array of file objects (as returned by getFilesData) and behaves differently based on its arguments:

  • If this method receives any files as arguments, only those files will be uploaded.
  • If no arguments are provided, all the selected files will be uploaded.
ej.base.enableRipple(true);

//Initialize the control by preload files
var uploadObj = new ej.inputs.Uploader({
    autoUpload: false,
    asyncSettings: {
        saveUrl: 'https://services.syncfusion.com/js/production/api/FileUploader/Save',
        removeUrl: 'https://services.syncfusion.com/js/production/api/FileUploader/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());
};
