I'm trying to fetch data through API , and the URL contains two object and I targeted the quizzes , "quizzes": [2 items], "warnings": []
quizzes return me two objects with their details.
what I'm trying to achieve is to add if statement to retrieve the grades (another API) depends on quiz name and it is working well , but I want to add inside it another if to retrieve grades depends on the another quiz name, please see the code below how to target posttest inside pretest they have the same key and I want the data to be changed depends on quiz name.
var get_quiz = {
"url": "MyURL"
};
$.ajax(get_quiz).done(function (get_quiz_res) {
var reslength = Object.keys(get_quiz_res).length;
for (let b = 0; b < reslength; b++) {
var get_grade = {
"url": "*******&quizid="+get_quiz_res.quizzes[b].id"
};
$.ajax(get_grade).done(function (get_grade_res) {
var posttest=''
if (get_quiz_res.quizzes[b].name === "Post Test"){
posttest = get_grade_res.grade;
}
if (get_quiz_res.quizzes[b].name === "Pre Test"){
var row = $('<tr><td>' + userincourseres[i].fullname + '</td><td>' + get_grade_res.grade + '</td><td>' + posttest + '</td><td>');
$('#myTable').append(row);
}
});
}
});
the userincourseres[i].fullname from another api and it is working.
You can use async/await with $ajax if your JQuery version is 3+.
const get_quiz = {
url: "MyURL",
};
(async function run() {
const get_quiz_res = await $.ajax(get_quiz);
const reslength = Object.keys(get_quiz_res).length;
for (let b = 0; b < reslength; b++) {
const get_grade = {
url: "*******&quizid=" + get_quiz_res.quizzes[b].id,
};
let posttest = "";
const get_grade_res = await $.ajax(get_grade);
if (get_quiz_res.quizzes[b].name === "Post Test") {
posttest = get_grade_res.grade;
}
if (get_quiz_res.quizzes[b].name === "Pre Test") {
var row = $(
"<tr><td>" +
userincourseres[i].fullname +
"</td><td>" +
get_grade_res.grade +
"</td><td>" +
posttest +
"</td><td>"
);
$("#myTable").append(row);
}
}
})();
I am currently trying to replace the name of a file in the Mid Server after a scheduled export.
The idea here is that the file goes with the name in the format "file_name_datetime" and the customer needs "datetime_file_name" for the file to be correctly read by another system.
My main idea was to rename the file after the export to the correct format, but if there is a way of changing the file name to the required one I could do that also.
I would love to hear from you guys as I have no idea how can I do this.
Thanks in advance.
If anyone is interested in the answer, see below:
Script include:
initialize: function() {
this.filePath = gs.getProperty('directory_path');
this.midServer = gs.getProperty('midserver');
this.authMidServerBase64 = gs.getProperty('authmidserver');
},
nameChange: function(exportSetName) {
var exportGr = new GlideRecord("sys_export_set_run");
exportGr.addEncodedQuery("set.nameSTARTSWITH" + exportSetName);
exportGr.orderByDesc("completed");
exportGr.query();
if (exportGr.next()) {
var attachSysID = exportGr.ecc_agent_attachment.sys_id;
}
var attachGr = new GlideRecord("sys_attachment");
attachGr.addEncodedQuery("table_sys_idSTARTSWITH" + attachSysID);
attachGr.query();
if (attachGr.next()) {
var attachName = attachGr.file_name;
var attachDate = attachName.match((/\d+/));
var newName = attachDate + '_' + exportSetName + '.csv';
}
var jspr = new JavascriptProbe(this.midServer);
jspr.setName('FileNameChange'); // This can be any name
jspr.setJavascript('var ddr = new MidServer_script_include(); res = ddr.execute();');
jspr.addParameter("verbose", "true");
jspr.addParameter("skip_sensor", "true"); // prevent Discovery sensors running for the ECC input
jspr.addParameter("filename", this.filePath + "\\" + attachName);
jspr.addParameter("filePath", this.filePath);

I am new to the IOT world and have been confused why I have not been able to use the Eclipse Paho JavaScript Client to connect to test.mosquitto.org.
I have used Port: 8080 and Path: /mqtt as has been suggested in other paho-mqtt questions, but am met with a Failed to connect: AMQJS0007E Socket error:undefined when using this Eclipse web client.
I have used the HiveMQ WebClient and have been able to connect, publish and subscribe to both test.mosquitto.org (Port 8080) and iot.eclipse.org (Port 443).
I have noticed that HiveMQ sources mqttws31.js compared to Paho Eclipse's paho-mqtt.js, but am unsure of the significance.
I would say there are two parts to this question:
What am I missing to get the Eclipse Paho JavaScript Client to connect to test.mosquitto.org ?
What is the difference between mqttws31.js and paho-mqtt.js that allows one to connect to test.mosquitto.org relatively painlessly compared to the other?
Thanks !

I think I am a bit late...but I leave here for posterity.
The Paho JS library has undergo a series of changes before release 1.0.3 and the last one 1.1.0.
If you refer to a mqttws31.js probably you was using a version earlier than 1.0.3, because from 1.0.3 the main js file was renamed to paho-mqtt.js.
Can be the reason why something in your code was working differently from HiveMQ version.
I tried to sum the situation here
I've been trying this for a while now, but I can't get my head around what's wrong. Maybe I've tried so many ways that I'm not even sure this piece of code is right anymore.
Basically I'm trying to use the track.scrobble method from the Last.fm API, sending a batch of tracks.
That's the code I have, and it's always returning Invalid method signature. Does anyone can give me some help here, please?
UPDATE
Based on mccannf answer, I've changed the code, but am still getting the error:
var apiUrl = "http://ws.audioscrobbler.com/2.0/";
var apiMethod = "track.scrobble";
var apiKey = "MY_API_KEY";
var apiSecret = "MY_API_SECRET";
var key = "MY_SESSION_KEY";
var apiSig = "";
var lastfmScrobble = function (data) {
var dataToScrobble = setTiming(data);
var albums = [];
var artists = [];;
var timestamps = [];
var tracks = [];
var dataToHash = "";
for (var i = 0; i < dataToScrobble.tracks.length; i++) {
albums["album["+ i.toString() + "]"] = dataToScrobble.album;
artists["artist[" + i.toString() + "]"] = dataToScrobble.artist;
timestamps["timestamp[" + i.toString() + "]"] = dataToScrobble.tracks[i].split("|")[1];
tracks["track[" + i.toString() + "]"] = dataToScrobble.tracks[i].split("|")[0];
}
dataToHash += albums.sort().join("");
dataToHash += "api_key" + apiKey;
dataToHash += artists.sort().join("");
dataToHash += "method" + apiMethod;
dataToHash += "sk" + key;
dataToHash += timestamps.sort().join("");
dataToHash += tracks.sort().join("");
dataToHash += apiSecret;
apiSig = $.md5(unescape(encodeURIComponent(dataToHash)));
var songsToScrobble = {};
$.extend(songsToScrobble,
albums.sort(),
{ api_key: apiKey },
{ api_sig: apiSig },
artists.sort(),
{ method: apiMethod },
{ sk: key },
timestamps.sort(),
tracks.sort());
$.ajax({
url: apiUrl,
type: "POST",
data: songsToScrobble,
success: function (data) {
console.log(data);
}
});
}
Now the object sent has the correct format (JSON). What can still be wrong?
I did a quick sample JS Fiddle of your code.
The dataToHash is like this:
album[0]Achtung Babyalbum[1]Achtung Babyapi_keyxxxBLAHxxxartist[0]U2artist[1]U2methodtrack.scrobbleskkkkFOOkkktimestamp[0]1379368800timestamp[1]1379369000track[0]Onetrack[1]The FlymmmySecrettt
The songsToScrobble variable in the code above looked like this:
{ "album": [
"album[0]Achtung Baby",
"album[1]Achtung Baby"
],
"api_key":"xxxBLAHxxx",
"api_sig":"8dbc147e533411a41ba9169f59e65b3a",
"artist":["artist[0]U2","artist[1]U2"],
"method": "track.scrobble",
"sk":"kkkFOOkkk"
"timestamp": [
"timestamp[0]1379368800",
"timestamp[1]1379369000"
],
"track": [
"track[0]One",
"track[1]The Fly"
]
}
I believe songsToScrobble should look like this:
{ "album[0]": "Achtung Baby",
"album[1]": "Achtung Baby",
"api_key":"xxxBLAHxxx",
"api_sig":"8dbc147e533411a41ba9169f59e65b3a",
"artist[0]": "U2",
"artist[1]": "U2",
"method": "track.scrobble",
"sk":"kkkFOOkkk"
"timestamp[0]": "1379368800",
"timestamp[1]": "1379369000",
"track[0]": "One",
"track[1]": "The Fly"
}
Only other minor point is to make sure dataToHash is UTF-8 encoded before you convert to MD5 hash.
Edit
This is how I created the data for the ajax call. NOTE: this is untested - I don't have a last.fm account.
var songsToScrobble = {};
function addDataToScrobble(parentElement, inputData) {
if ($.isArray(inputData)) {
$.each(inputData, function(index ,element) {
songsToScrobble[parentElement + "[" + index + "]"] = element;
dataToHash += parentElement + "[" + index + "]" + element;
});
} else {
songsToScrobble[parentElement] = inputData;
dataToHash += parentElement + inputData;
}
}
for (var i = 0; i < data.tracks.length; i++) {
albums.push(data.album);
artists.push(data.artist);
// The tracks are coming in the format: title|timestamp
timestamps.push(data.tracks[i].split("|")[1]);
tracks.push(data.tracks[i].split("|")[0]);
}
addDataToScrobble("album", albums);
addDataToScrobble("api_key", apiKey);
addDataToScrobble("artist", artists);
addDataToScrobble("method", apiMethod);
addDataToScrobble("sk", key);
addDataToScrobble("timestamp", timestamps);
addDataToScrobble("track", tracks);
apiSig = $.md5(unescape(encodeURIComponent(dataToHash+apiSecret)));
songsToScrobble["api_sig"] = apiSig;
$.ajax({
url: apiUrl,
type: "POST",
data: songsToScrobble,
success: function (data) {
console.log(data);
}
});
I am trying get paged json responses from Topsy (http://code.google.com/p/otterapi/) and am having problems merging the objects. I want to do this in browser as the api rate limit is per ip/user and to low to do things server side.
Here is my code. Is there a better way? Of course there is because this doesn't work. I guess I want to get this working, but also to understand if there is a safer, and/or more efficient way.
The error message I get is ...
TypeError: Result of expression 'window.holdtweetslist.prototype' [undefined] is not an object.
Thanks in advance.
Cheers
Stephen

You are calling Merge as an static method, but declared it as an "instance" method (for the prototype reserved word).
Remove prototype from Merge declaration, so you'll have:
window.holdtweetslist.Merge = (function(ob)...
This will fix the javascript error.
This is Vipul from Topsy. Would you share the literal JSON you are receiving? I want to ensure you are not receiving a broken response.
THanks to Edgar and Vipul for there help. Unfortunately they were able to answer my questions. I have managed to work out that the issue was a combination of jquery not parsing the json properly and needing to use jsonp with topsy.
Here is a little test I created that works.
Create a doc with this object on it ....
RUN TEST
You will need JQUERY
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
And put the following in a script too. The is cycle through the required number of tweets from Topsy.
Thanks again everyone.
