I'm running a loop and trying to insert the multiple values from an array while running it.
Here is the code:
function GetJobsToCourseID(index, jobData){
if((jobData != undefined)||(jobData != null)){
var extrArray = [];
for(var i = 0 ; i< jobData.length; i++){
extrArray = jobData[i];
for (var j=0; j<extrArray.length; j++)
{
console.log(extrArray[j]);
requestID = new Request("SELECT IDKey from dbo.Jobz where SubJobFamily ='"+extrArray[j]+"'", function(err, rowCount){
if (err) {
console.log(err);
}
else { connection111.reset(function(err){});
}
});
}
}
}
requestID.on('row', function(columns) {
for (var i = 0; i <columns.length; i++)
{
console.log(columns[i].value, "Please work");
if (columns[i].value == null || columns[i].value == undefined) {
console.log('NULL');
} else {
}
}
connection111.execSql(requestID);
});
}
As you can see I'm trying to insert the j element of my tempArray(I dont think it should work anyways, because of how Tedious connections work)
What would be the approach then - extracting each array element and populating it withing the SQL table using Tedious?
Fixed it by adding a connection pool and an changing the second loops var j to let j ... 'tedious' is really tedious...
here is the code:
function GetJobsToCourseID(index, jobData){
if((jobData != undefined)&&(jobData != null)){
var extrArray = [];
var newArray = [];
for(var i = 0 ; i< jobData.length; i++){
extrArray = jobData[i];}
for (let j=0; j<extrArray.length; j++){
pool.acquire(function (err, connection1111) {
if (err)
console.error(err);
requestID = new Request("SELECT IDkey from dbo.Jobz where SubJobFamily ='"+extrArray[j]+"'", function(err, rowCount){
if (err) {
console.log(err);
}
else {connection1111.reset(function(err){});}});
requestID.on('row', function(columns) {
for (var i = 0; i <columns.length; i++){
if (columns[i].value == null || columns[i].value == undefined) {
console.log('NULL');
} else {
arty.push(columns[i].value);
console.log(arty);
}}
});
connection1111.execSql(requestID);
});}
pool.on('error', function (err) {
console.error(err);
});
}}

I'd like to send base64 image as an attachment to a trello card through the API
POST /1/cards/[card id or shortlink]/attachments
There's a file field but it does not specify how should look the data there.
Refs: https://developers.trello.com/advanced-reference/card#post-1-cards-card-id-or-shortlink-attachments
Any idea?
Short answer: Trello's API only works to attach binary data via multipart/form-data. Examples below.
Long answer:
The Trello API to add attachments and images is frustratingly under-documented. They do have a coffeescript Client.js for those of us using Javascript to simplify all the basic operations: https://trello.com/1/client.coffee
Using the vanilla Client.js file I have been able to attach links and text files. While the CURL example shows pulling a binary file in from a hard drive, that doesn't work for those of us completely on a server or client where we don't have permissions to create a file.
From a LOT of trial and error, I've determined all binary data (images, documents, etc.) must be attached using multipart/form-data. Here is a jQuery snippet that will take a URL to an item, get it into memory, and then send it to Trello.
var opts = {'key': 'YOUR TRELLO KEY', 'token': 'YOUR TRELLO TOKEN'};
var xhr = new XMLHttpRequest();
xhr.open('get', params); // params is a URL to a file to grab
xhr.responseType = 'blob'; // Use blob to get the file's mimetype
xhr.onload = function() {
var fileReader = new FileReader();
fileReader.onload = function() {
var filename = (params.split('/').pop().split('#')[0].split('?')[0]) || params || '?'; // Removes # or ? after filename
var file = new File([this.result], filename);
var form = new FormData(); // this is the formdata Trello needs
form.append("file", file);
$.each(['key', 'token'], function(iter, item) {
form.append(item, opts.data[item] || 'ERROR! Missing "' + item + '"');
});
$.extend(opts, {
method: "POST",
data: form,
cache: false,
contentType: false,
processData: false
});
return $.ajax(opts);
};
fileReader.readAsArrayBuffer(xhr.response); // Use filereader on blob to get content
};
xhr.send();
I have submitted a new coffeescript for Trello developer support to consider uploading to replace Client.js. It adds a "Trello.upload(url)" that does this work.
I've also attached here for convenience in JS form.

my calculated route works good so far, but I have some trouble with my destination address.
When the destination is within a pedestrian area (city center), this destination (lat, long) will set to the next valid street. This is probably how it supposed to be, but it's important that I get the route until the specific destination address. What I want: E.g. I drive into the pedestrian area or I drive as far as possible by car and then walk to the destination.
Anyone has an idea how I can solve this problem? I am using the following code, the code works so that is not the problem:

I've been trying to get this works, but I don't know what's wrong, can you guys help me? I tried WebRTC code with modification like this.
Both caller and callee enter the web
Web will create channel based on their username
Caller clicks the call button and sends message to spesific channel to some user's username. When caller clicks the call button, he then creates peerConnection and adds localStream
Callee will receive message, and the process goes on like WebRTC sample code. When callee receives an offer, he then creates peerConnection and adds localStream, then creates and sends answer
My code goes like this
var my_username = '{{ current_username }}';
var friend;
var localVideo;
var remoteVideo;
var localStream;
var remoteStream;
var channel;
var channelReady = false;
var pc;

When it comes to waitForRemoteVideo, the function calls the else condition. But the blob url for remoteVideo exists.
It's funny that I've been searching for the error and re-writing the code for like three times, and suddenly after posted my question here, I realized my mistake.
Here in the function processSignallingMessage..
if (data_message.type === 'offer') {
// Callee creates PeerConnection
if (!started)
maybeStart();
pc.setRemoteDescription(new RTCSessionDescription(data_message));
friend = send_info.from;
doAnswer();
} else ....
Should be like this:
if (data_message.type === 'offer') {
friend = send_info.from;
// Callee creates PeerConnection
if (!started)
maybeStart();
pc.setRemoteDescription(new RTCSessionDescription(data_message));
doAnswer();
} else ....
because callee need variable friend to be filled before sending candidate message.
