Is there a JavaScript InDesign function to get ID value

I used the command to export the hard drive ID to drive C:
var command="wmic diskdrive get SerialNumber > C:/idhdd.txt";
app.system("cmd.exe /c\""+command+"" );
I get the text file
SerialNumber
2012062914345300
Is there a JavaScript statement to remove SerialNumber, I just want to get the ID in the text file and save it to the hard drive C.

Here's ready-to-use getDriveIDs() function that should work in any Adobe app and will return array of HDD ID strings for you. I hope this can be easily generalized for other scenarios with Windows scripting inside Adobe scripting ;-)
//----------------------------------------------------------------------//
// Detects IDs (serial numbers) of connected drives and returns them as array of strings.
var getDriveIDs = function() {
var idFile = File(Folder.temp + '/saved_hdd_serials.txt');
var scriptFile = File(Folder.temp + '/dump_hdd_serials.bat');
var scriptContent = 'wmic diskdrive get SerialNumber > ' + idFile.fsName + '\n';
var ids = []
withTempFile(scriptFile, scriptContent, function() {
scriptFile.execute();
$.writeln(idFile.length == 0); // wait for asynchronous script execution to finish
$.sleep(1);
withTempFile(idFile, undefined, function(file, lines) {
ids = lines.slice(1);
});
});
return ids;
};
//----------------------------------------------------------------------//
// utilities
var withTempFile = function(file, content, callback) {
if (undefined == content) { // read temp file
file.open('r');
content = [];
while (!file.eof)
content.push(file.readln());
} else { // write temp file
file.open('w');
file.write(content);
content = undefined;
}
file.close();
callback(file, content);
file.remove();
}
//----------------------------------------------------------------------//
// main: demo
var ids = getDriveIDs();
alert('Drive IDs:\n\t' + ids.join('\n\t'));

Google Drive + Script throws permissions error even through I'm owner and granted permission

I'm trying to create a basic script on a 12-hour timer trigger that loops through each of my Google Calendars by their ICAL URL, and downloads the ICAL for a folder on my Google Drive (for backup purposes). It throws this error
"No item with the given ID could be found, or you do not have permission to access it. (line 23, file "Code")" (Line #23 is var folder... )
Running the script does download and save the ICAL file on the first run through the loop (and if I manually pass in each unique ICAL URL one at a time), but the error then terminates the loop. Seeing as how I've authorized access already and am the owner of everything here, I'm not sure what else I need.
var calendarsToSave = [
"https://calendar.google.com/calendar/ical/inXXXXXXX.com/privateXXXX/basic.ics",
"https://calendar.google.com/calendar/ical/XXXXX.com_XXXXXXup.calendar.google.com/private-XXXXXXX/basic.ics"
];
var folder = '123xxxxxxxxv789'; // my gdrive folder
function downloadFile(calendarURL,folder) {
var fileName = "";
var fileSize = 0;
for (var i = 0; i < calendarsToSave.length; i++) {
var calendarURL = calendarsToSave[i];
var response = UrlFetchApp.fetch(calendarURL, {muteHttpExceptions: true});
var rc = response.getResponseCode();
if (rc == 200) {
var fileBlob = response.getBlob()
var folder = DriveApp.getFolderById(folder); // << returns a permissions error thus terminating the for loop
var file = folder.createFile(fileBlob);
fileName = file.getName();
fileSize = file.getSize();
}
var fileInfo = { "rc":rc, "fileName":fileName, "fileSize":fileSize };
return fileInfo;
} // end for loop
}

Updated: You are also re-initializing a variable that already exists from the parameters and as a global variable so we can remove the parameter if you want to keep the global variable.
We can also move the place where you get the Google Folder object. It stays the same every time so we don't need to retrieve it again.
var calendarsToSave = [
"https://calendar.google.com/calendar/ical/inXXXXXXX.com/privateXXXX/basic.ics",
"https://calendar.google.com/calendar/ical/XXXXX.com_XXXXXXup.calendar.google.com/private-XXXXXXX/basic.ics"
];
var folder = '123xxxxxxxxv789'; // my gdrive folder
function downloadFile(calendarURL) {
var fileName = "";
var fileSize = 0;
var gfolder = DriveApp.getFolderById(folder);
for (var i = 0; i < calendarsToSave.length; i++) {
var calendarURL = calendarsToSave[i];
var response = UrlFetchApp.fetch(calendarURL, {muteHttpExceptions: true});
var rc = response.getResponseCode();
if (rc == 200) {
var fileBlob = response.getBlob()
var file = gfolder.createFile(fileBlob);
fileName = file.getName();
fileSize = file.getSize();
}
var fileInfo = { "rc":rc, "fileName":fileName, "fileSize":fileSize };
return fileInfo;
} // end for loop
}
Let see where that gets us.

Your "folder" variable is outside the function, causing the data to be inaccessible to the "downloadFile" function.
Google apps coding seems to require variables to be in a function to be defined. I would recommend moving both "calendarsToSave" and "folder" to the inside of "downloadFile"
Here is an example that will return your error:
var folder = '1HSFBPfPIsXWvFEb_AalFYalkPwrOAyxD';
function myFunction() {
var folder = DriveApp.getFolderById(folder);
var name = folder.getName();
Logger.log(name);
}
And here is one that will return the file name:
function myFunction() {
var folder = '1HSFBPfPIsXWvFEb_AalFYalkPwrOAyxD';
var folder = DriveApp.getFolderById(folder);
var name = folder.getName();
Logger.log(name);
}

Export to csv in ui-grid : exporterAllDataFn fires only when we have more than one page

exporterAllDataFn event fires only when we have more than one page : when i reduce the page size and i have two pages it fires but when i have only one page it doesn't fire.i have some code in exporterAllDataFn that must be run each time . is there any solution or other way to run some piece of code before exporting ?!!

you can use it to call a new function which you can handle the downloading of CSV:
exporterAllDataFn: function () {
$scope.downloadCSV();
}
and handled the csv here:
$scope.downloadCSV = function () {
paramsObj['query'] = $scope.keyword;
$scope.downloadCSVPromise = Material.query(paramsObj, function (response) {
if (response && response.partSearchList && response.partSearchList.length > 0) {
$scope.noData = false;
$scope.numFound = response.numFound;
**var csv = JSON2CSV(response.partSearchList);**
//window.open("data:text/csv;charset=utf-8," + escape(csv))
if (window.navigator.msSaveOrOpenBlob) {
var blob_ie = new Blob([decodeURIComponent(encodeURI(csv))], {
type: "text/csv;charset=utf-8;"
});
navigator.msSaveBlob(blob_ie, 'FileName.csv');
}
var date = new Date();
var today = date.toString().substr(4,20);
var regex = new RegExp(" ", 'g');
today = today.replace(regex, '_');
var fileNm = 'AGSExtract_'+today+'.csv';
var downloadLink = document.createElement("a");
var blob = new Blob(["\ufeff", csv]);
var url = URL.createObjectURL(blob);
downloadLink.href = url;
downloadLink.download = fileNm;
document.body.appendChild(downloadLink);
downloadLink.click();
document.body.removeChild(downloadLink);
} else {
$scope.noData = true;
}
});
};
Above solution is for server side full data, if you are using client side pagination then check for JSON2CSV and pass the $scope variable which has the table data.
Hope this helps :)

URL encoding "data:image/jpg; base64" image

How can I encode the data:image/jpeg;base64 data url to be transmitted correctly through an AJAX POST. I have the following code xhr.open('POST', 'http://url-sent-to/image/' + saveImage + '&imageid=' + imageid.value, true); that is doing so now.
However, the URL http://url-sent-to/image/data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD…RRQAUUUUAFFFFABRRRQAUUUUAFFFFABRRRQAUUUUAFFFFAH/2Q==&imageid=testimagedata does not look like it will be correct, especially since it has = in it.
$(function () {
var fileInput = document.getElementById("file")
, renderButton = $("#renderButton")
, imgly = new ImglyKit({
container: "#container",
ratio: 1 / 1
});
// As soon as the user selects a file...
fileInput.addEventListener("change", function (event) {
var file;
var fileToBlob = event.target.files[0];
var blob = new Blob([fileToBlob], {"type":fileToBlob.type});
// do stuff with blob
console.log(blob);
// Find the selected file
if(event.target.files) {
file = event.target.files[0];
} else {
file = event.target.value;
}
// Use FileReader to turn the selected
// file into a data url. ImglyKit needs
// a data url or an image
var reader = new FileReader();
reader.onload = (function(file) {
return function (e) {
data = e.target.result;
// Run ImglyKit with the selected file
try {
imgly.run(data);
} catch (e) {
if(e.name == "NoSupportError") {
alert("Your browser does not support canvas.");
} else if(e.name == "InvalidError") {
alert("The given file is not an image");
}
}
};
})(file);
reader.readAsDataURL(file);
});
// As soon as the user clicks the render button...
// Listen for "Render final image" click
renderButton.click(function (event) {
var dataUrl;
imgly.renderToDataURL("image/jpeg", { size: "1200" }, function (err, dataUrl) {
// `dataUrl` now contains a resized rendered image with
// a width of 300 pixels while keeping the ratio
//Convert DataURL to Blob to send over Ajax
function dataURItoBlob(dataUrl) {
// convert base64 to raw binary data held in a string
// doesn't handle URLEncoded DataURIs - see SO answer #6850276 for code that does this
var byteString = atob(dataUrl.split(',')[1]);
// separate out the mime component
var mimeString = dataUrl.split(',')[0].split(':')[1].split(';')[0];
// write the bytes of the string to an ArrayBuffer
var ab = new ArrayBuffer(byteString.length);
var ia = new Uint8Array(ab);
for (var i = 0; i < byteString.length; i++) {
ia[i] = byteString.charCodeAt(i);
}
// write the ArrayBuffer to a blob, and you're done
//var bb = new BlobBuilder();
//bb.append(ab);
//return bb.getBlob(mimeString);
}
var blob = dataURItoBlob(dataUrl);
var fd = new FormData(document.forms[0]);
var xhr = new XMLHttpRequest();
var saveImage = dataUrl;
//console.log(saveImage);
fd.append("myFile", blob);
xhr.open('POST', 'http://url-sent-to/image/' + saveImage + '&imageid=' + imageid.value, true);
xhr.send(fd);
I have a fiddle setup for an example of what I'm doing. Essentially, the user will select an image, enter a description, and hit render. When you check the Javascript console, you'll see a Blob is created, and the POST message at the bottom: http://jsfiddle.net/mattography/Lgduvce1/2/

You're looking for encodeURI(), which will do exactly what you're looking for.
Note that you're missing a ? to start your querystring.
Also note that making URLs that long is a bad idea; you should send a POST request instead.

Save image file in sdcard in firefox OS

I am trying to save an image in sdcard. I am following this documentation.
$('.btnSave').on('click', function () {
var imageRawData = canvas.toDataURL("image/png") ;
var sdcard = navigator.getDeviceStorage("sdcard");
var file = new Blob([imageRawData], { type: "image/png" });
var request = sdcard.addNamed(file, "FilertedImage.png");
request.onsuccess = function () {
var name = this.result;
console.log('File "' + name + '" successfully wrote on the sdcard storage area');
}
request.onerror = function (e) {
console.log('Unable to write the file: ' + e.target.error.name);
}
});
In the documentation I found that "pictures only accepts Blob with a valid image mime type". So how can I convert imageRawData to valid image mime type using javascript.

I have done it like the following - Saves and then shares:
function saveAndSend(blob) {
var sdcard = navigator.getDeviceStorage("sdcard");
var request = sdcard.addNamed(blob, "test/mycanvas.png");
//could just share the blob instead of saving
request.onsuccess = function () {
var sharingImage = new MozActivity({
name: "share",
data: {
type: "image/*",
number: 1,
blobs: [blob],
filenames: ["mycanvas.png"],
filepaths: ["test/mycanvas.png"]
}
});
}
// An error could occur if a file with the same name already exist
request.onerror = function () {
alert('Unable to write the file: ' + this.error.name);
}
}
var cnv = document.getElementById('myCanvas');
cnv.toBlob(function (blob) {
//var sdcard = navigator.getDeviceStorage("pictures");
var sdcard = navigator.getDeviceStorage("sdcard");
var request = sdcard.delete("test/mycanvas.png");
//try to delete in case it exists
request.onsuccess = function () {
saveAndSend(blob);
}
request.onerror = function () {
saveAndSend(blob);
}
});

Your app also need to make sure that it has the appropriate device storage permissions.
See: https://github.com/mozilla-b2g/gaia/blob/master/dev_apps/ds-test/manifest.webapp#L13 for an example. ds-test is a test app I wrote for testing things in device storage.
