function($scope, $q) {
$scope.extractArchive = function(zipfile) {
var dfd = $q.defer();
var reader = new FileReader();
reader.onerror = dfd.reject.bind(dfd);
reader.onload = function(e) {
if (!reader.result) dfd.reject(new Error("Unknown error"));
var zip = new JSZip(reader.result);
return dfd.resolve(zip);
};
reader.readAsArrayBuffer(zipfile);
return dfd.promise;
}
function onArchiveChange(evt) {
var target = evt.dataTransfer || evt.target;
var file = target && target.files && target.files[0];
$scope.extractArchive(file)
.then(function(zipFile) {
console.log(zipFile)
})
}
angular.element(document.querySelector('#archiveUpload01')).on('change', onArchiveChange);
}
])

Use the async method to get a promise of the content (which behave like $q):
zip.file("Positions.csv").async("text")
.then(function success(txt) {
console.log("csv is", txt);
}, function error(e) {
console.error(e);
});
Edit: the code above is for JSZip v3, you use JSZip v2:
var txt = zip.file("Positions.csv").asText();
console.log("csv is", txt);
zip.file("Positions.csv") will give you the ZipObject you show on your image.
Edit 2: extractArchive, written for JSZip v3, looks like:
$scope.extractArchive = function(zipfile) {
return JSZip.loadAsync(zipfile); // JSZip v3 can read Blobs and Files
}; // returns a promise of a JSZip instance
You can then chain other promises:
$scope.extractArchive(zipfile).then(function (zip) {
return zip.file("Positions.csv").async("arraybuffer");
}).then(function (buf) {
var blob = new Blob([buf]);
// ...
})
