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.
ej.base.enableRipple(true);
//Initialize the control by preload files
var uploadObj = new ej.inputs.Uploader({
autoUpload: false,
asyncSettings: {
saveUrl: 'https://ej2.syncfusion.com/services/api/uploadbox/Save',
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());
};
