I am using the EXPORT-CSV plugin for Highcharts to export data to csv. (Thank you to the developers of this plugin!) When testing in Safari on a Mac, however, the exported csv file does not take the filename as expected from
exporting: {
filename: "FancyFileName"
}
and instead just uses the default Highcharts name "chart". All the built-in export types do use the desired filename from Safari, and the csv also gets the desired filename from all the other standard browsers I have tested.
Here is a fiddle.
How can Safari be convinced to use the filename I give it? Thanks for your help.
The hard coded filename is coming from the php script written on the server. You can find that script on php script for download of file with hardcoded file name
You can use that same code on your local machine server. To do that
create a php file on your local server.
copy the above code in it.
change url www.highcharts.com/studies/csv-export/csv.php in export.csv library to your local server url.
change the name whatever you wish to using $_POST['variablename']
Variable name should be pass when making post call from export.csv library and use in php file using $_POST
Highcharts.post(url, {
data: content,
name: name,
type: MIME,
extension: extension
});
This is the code used in export.csv library for making post call. I have added extra parameter name to be used in my php script for dynamic filename.

I am trying to localize a push notification text while inside a Parse Cloud function and after many tries I was not able to have working solution. Is there a way to localized text inside a Parse Server cloud function?
So, for anyone looking for a solution, I used the following library: i18n-node.
Then in the cloud code (I am using Typescript):
import i18n from 'i18n';
//... other imports
i18n.configure({
locales:['en', 'it'],
directory: __dirname + '/locales'
});
And then inside a cloud function is possible to run:
i18n.__({phrase: "Hey, well done!", locale: locale}
Where locale can come from the request or, in my case, from the user's device language preference.
I had the same problem, and solve it with UTF-8 encoding before sending the notification.
npm package: UTF8
Usage:
var utf8 = require("utf8");
// encode before sending the text
text = utf8.encode(text);
How to change url path of socket.io.js
my socket.io.js is located at
https://192.168.236.100/socket.io/socket.io.js
what if i want to change it like:
https://192.168.236.100/socket.conference/socket.io.js
thank you
It is not as simple as changing the this._path value or passing in the path option to the constructor because if you change that, it also affects how a socket.io client must connect to the server too, not only how the socket.io.js file is served.
The simplest way I could find to make the socket.io.js file appear to be coming from a different path and not change anything else is to just create a new route for it like this:
app.get("/socket.conference/socket.io.js", function(req, res) {
res.sendFile(path.join(__dirname, "node_modules/socket.io-client/socket.io.js"));
});
This assumes that socket.io is installed locally in the directory that your app file is running from. If it is installed somewhere differently, then you need to find where the /socket.io-client/socket.io.js path/file is and use the right path to that.
This works with this client <script> tag:
<script src="/socket.conference/socket.io.js"></script>
I'm trying to implement a local copy of a TileJSON in an iOS app through Cordova. The issue I'm having is that OpenLayers doesn't seem to recognise the JSON file as valid and thus doesn't show any tiles. I have tried local and remote versions of the same TileJSON and looked at the Console Logs, the local one has a status of "error" (but no explanation as to what that error might be...).
I think the issue is down to the fact that the JSON file is being loaded using a file: URL, rather than http:. I have put the JSON file on a remote server and this not only loads fine but actually loads the tiles from the local path.
Can OpenLayers be tricked into accepting the local file as a valid JSON file? Can Cordova be forced to load local files via HTTP? I think either of these options would fix the issue.
Thanks
EDIT: Here's the code I'm using to load the TileJSON:
var mapLayer = new ol.layer.Tile({
source: new ol.source.TileJSON({
url: getPhoneGapPath() + 'tiles.json',
crossOrigin: 'anonymous'
})
});
this.map.addLayer(mapLayer);
function getPhoneGapPath() {
var path = window.location.pathname;
path = path.substr( path, path.length - 10 );
return path;
}
The getPhoneGapPath() function is used to get the path to the webroot of the Cordova app.
This is probably related to a bug in OpenLayers, https://github.com/openlayers/ol3/issues/5647. The fix will be in the next release.
Also make sure that you configure Cordova to allow access to file:// urls when the application is served from a file:// url. The equivalent option in Chrome is --allow-file-access-from-files.
I have a Cordova/PhoneGap app which uses the camera to capture a picture. I need to access this picture to send to my server.
For Android I simply use $cordovaFile.readAsDataURL(cordova.file.dataDirectory, fileName)
However; on iOS the filename does not come back as such. My return value for iOS shows the path as
assets-library://asset/asset.JPG?id=539425FE-43AA-48E7-9865-D76348208AC7&ext=JPG
How can I access and read this image? I'd prefer to stick with $cordovaFile but just want to get it to work.
I am using CordovaCameraPreview plugin and the best I can get back from the picture taker handler seems to be something formed similar to:
assets-library://asset/asset.JPG?id=990355E1-200A-4E35-AAA1-7D461E3999C8&ext=JPG
assets-library://asset/asset.JPG?id=C49FF0EB-CCCB-45B2-8577-B13868D8DB29&ext=JPG
How can I convert this to a filename and path that I can read with $cordovaFile? According to their documentation (http://ngcordova.com/docs/plugins/file/) it looks like I need to use one of their paths for File System Layout. It works fine on Android using cordova.file.dataDirectory but can't figure out how to access on iOS
I've also tried using window.resolveLocalFileSystemURL(path) but am getting undefined as my result.
Update
I feel like I'm getting closer... using window.resolveLocalFileSystemURL(path,resolveOnSuccess, resOnError); I get more information
name: "assets-library"
fullPath: "/asset/asset.JPG?id=711B4C9D-97D6-455A-BC43-C73059A5C3E8&ext=JPG"
name: "asset.JPG?id=711B4C9D-97D6-455A-BC43-C73059A5C3E8&ext=JPG"
nativeURL: "assets-library://asset/asset.JPG?id=711B4C9D-97D6-455A-BC43-C73059A5C3E8&ext=JPG"
It looks like I now need to use the fullPath but still can't figure out how to access with $cordovaFile
If I try to use $cordovaFile.readAsDataURL(cordova.file.dataDirectory, data.name) where data.name is asset.JPG?id=711B4C9D-97D6-455A-BC43-C73059A5C3E8&ext=JPG I get a file not found error
Update 2
I have tried using every single File System Layout available at http://ngcordova.com/docs/plugins/file/ and receive the same File Not Found error on each one. Still no clue how to access a file in assets-library using $cordovaFile
I had success with a simple substitution, like this
fullPath = fullPath.replace("assets-library://", "cdvfile://localhost/assets-library/")
It works in iOS 9.3
I was struggling with a similar issue for a while, but I figured it out today. I also thought that the FileSystem APIs didn't work with assets-libary:// URIs -- but that is not the case.
You should be able to get access to the File object (as well as the actual image name) by using the following code:
resolveLocalFileSystemURL('assets-library://asset/asset.JPG?id=711B4C9D-97D6-455A-BC43-C73059A5C3E8&ext=JPG', function(fileEntry) {
fileEntry.file(function(file) {
var reader = new FileReader();
reader.onloadend = function(event) {
console.log(event.target.result.byteLength);
};
console.log('Reading file: ' + file.name);
reader.readAsArrayBuffer(file);
});
});
I'm new with lua but working on an application that works on specific files with given path. Now, I want to work on files that I download. Is there any lua libraries or line of codes that I can use for downloading and storing it on my computer ?
You can use the LuaSocket library and its http.request function to download using HTTP from an URL.
The function has two flavors:
Simple call: http.request('http://stackoverflow.com')
Advanced call: http.request { url = 'http://stackoverflow.com', ... }
The simple call returns 4 values - the entire content of the URL in a string, HTTP response code, headers and response line. You can then save the content to a file using the io library.
The advanced call allows you to set several parameters like HTTP method and headers. An important parameter is sink. It represents a LTN12-style sink. For storing to file, you can use sink.file:
local file = ltn12.sink.file(io.open('stackoverflow', 'w'))
http.request {
url = 'http://stackoverflow.com',
sink = file,
}
