Uploading a file with FormData and multer

Question

I have successfully managed to upload a file to a Node server using the multer module by selecting the file using the input file dialog and then by submitting the f

Answer 1

to post a FormData object accepted by multer the upload function should be like this:

function uploadFile(fileToUpload, url) { 
    var formData = new FormData();
    //append file here 
    formData.append('file', fileToUpload, fileToUpload.name);
    //and append the other fields as an object here
    /* var user = {name: 'name from the form',
        email: 'email from the form' 
        etc...       
    }*/
    formData.append('user', user);

    // This function simply creates an XMLHttpRequest object
    // Opens the connection and sends form_data
    doJSONRequest("POST", "/tracks/upload", null, formData, function(d) {
        console.log(d);
    })
}
