javascript - Read the contents of a "file" object? -
so have "file" object (retrieved handling file drag , drop desktop). can send files server ajax, , throw them javascript handle them. possible read contents of without doing this?
here, play around fiddle. drag file box , use variable file
.
i've tried of methods of object...no luck. can contents of file dragged browser?
ps: send files server this:
var ajaxrequest = new xmlhttprequest(); ajaxrequest.open("returnrawpostdata.php"); ajaxrequest.send(file);
i might have missed in code above, that's because 1 doesn't use plain js ajax calls anymore.
using links martin mally (thanks lot!), came this:
var file = e.datatransfer.files[0],read = new filereader(); read.readasbinarystring(file); read.onloadend = function(){ console.log(read.result); }
where read.result
holds contents of file.
