I actually have a file input and I would like to retrieve the Base64 data of the file.
I tried:
$('input#myInput')[0].files[0] to retrieve the data. But it only provides the name, the length, the content type but not the data itself.
I actually need these data to send them to Amazon S3
I already test the API and when I send the data through html form with encode type "multipart/form-data" it works.
I use this plugin : http://jasny.github.com/bootstrap/javascript.html#fileupload
And this plugins gives me a preview of the picture and I retrieve data in the src attribute of the image preview. But when I send these data to S3 it does not work. I maybe need to encode the data like "multipart/form-data" but I don't know why.
Is there a way to retrieve these data without using an html form?

File Input and Output in C 1) Create a variable to represent the file. 2) Open the file and store this "file" with the file variable. 3) Use the fprintf or fscanf functions to write/read from the file.
To read a file, use FileReader , which enables you to read the content of a File object into memory. You can instruct FileReader to read a file as an array buffer, a data URL, or text.
input file element:
<input type="file" id="fileinput" /> get file :
var myFile = $('#fileinput').prop('files'); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
