I'm trying to figure out how to map this async function onto an array that I am using. The code that I tried is returned undefined since the promise isn't completing.
I am using NPM twit and this is the function that is supposed to return a number when an ID is passed into it
ids = ['1084212656771350532','2450457644','1244639845743570948','1081269935031140353','1227966230511980550','752215003143430145']
T.get('statuses/user_timeline', { user_id: id, count: 100, exclude_replies: true, include_rts: false }, function (err, data, response) {
if (err) {
console.log('err');
} else {
var rtTotal = 0;
var likeTotal = 0;
for (var i = 0; i < data.length; i++) {
rtTotal += data[i].retweet_count;
var rtAverage = rtTotal / data.length;
}
for (var i = 0; i < data.length; i++) {
likeTotal += data[i].favorite_count;
var likeAverage = likeTotal / data.length;
}
}
var influenceScore = (.33 * rtAverage) + (.2 * likeAverage) + (.33 * (data[0].user.followers_count)) + (.14 * (data[0].user.statuses_count));
console.log(influenceScore);
return influenceScore;
})
For example the result should be an array with numerical values
[1123.11, 9200, 21882, 1011, 23110.22]

Need to find out "chacesofrain" for each of the time for the next 14 days
Can only print the chanceofrain for the first day.Not sure how I can get for the rest of the days?
[![$('#weather-click').click(function() {
var state = $('#state')
.val()
.trim();
var country = $('#country')
.val()
.trim();
var queryURL = `http://api.worldweatheronline.com/premium/v1/weather.ashx?key=[API_KEY]&q=${state},%20${country}&format=json&num_of_days=14`;
$.ajax({
url: queryURL,
method: 'GET'
}).then(function(response) {
console.log(response);
var weather = response.data.weather;
console.log(weather);
for (var i = 0; i < weather.length; i++) {
var hourly = weather[i].hourly;
console.log(hourly);
for (var k = 0; k <= hourly.length; k++) {
var chanceOfRain = hourly[k].chanceofrain;
console.log(chanceOfRain);
}
// setTimeout(function() {
// for (var k = 0; k <= hourly.length; k++) {
// var changeOfRain = hourly[k].chanceofrain;
// console.log(changeOfRain);
// }
// }, 4000);
}
});

I expect chanceofrain for all the days logged in the browser
But the output shows for only 1 day
I'm trying to create a Parse cloud code function that returns the same result as a GET on parse/classes/MyClass but with the IDs of the relations.
I've done it for one object, but I can't make it work in a loop to get all the objects.
This is how I'm trying to get all the objects. It's working without the for loop and with r as a response.
Parse.Cloud.define('get_ClassName', function(request, response) {
let query = new Parse.Query('ClassName');
var ret = {};
query.find({useMasterKey: true}).then(function(results) {
for (var i = 0; i < results.length; i++) {
ret[i] = {};
const relQuery = results[i].get('status').query();
relQuery.find({useMasterKey: true}).then(function(res) {
var ids = {};
for (var j = 0; j < res.length; j++) {
ids[j] = res[j].id;
}
var status = {...status, id: ids};
status["className"] = "Status";
var r = {...r, status: status};
r["tag"] = results[i].get("tag");
ret[i] = r; //Can't access ret
//response.success(r); //Working
})
}
response.success(ret);
});
});
This is the actual result for the working version:
{
"result": {
"status": {
"id": {
"0": "xxxxxx",
"1": "xxxxxx"
},
"className": "Status"
},
"tag": "value"
}
}
response.success(ret); will run before relQuery.find finish in for loop.
Use Promise.all()
or Async await and refactor your logic.
I comment on your code about your missing.
Parse.Cloud.define('get_ClassName', function(request, response) {
let query = new Parse.Query('ClassName');
var ret = {};
query.find({useMasterKey: true}).then(function(results) { // Asyncronous
for (var i = 0; i < results.length; i++) {
ret[i] = {};
const relQuery = results[i].get('status').query();
relQuery.find({useMasterKey: true}).then(function(res) { // Asyncronous
var ids = {};
for (var j = 0; j < res.length; j++) {
ids[j] = res[j].id;
}
var status = {...status, id: ids};
status["className"] = "Status";
var r = {...r, status: status};
r["tag"] = results[i].get("tag");
ret[i] = r; //Can't access ret
//response.success(r); //Working
console.log(`index {i}`, r);
})
}
console.log(`response will be called`);
response.success(ret); // Called before `relQuery.find` finish
});
});
I am trying to add values in a multidimensional array in JavaScript, but it doesn't seem to work. I get "variable not defined" error in snippet but can't see any variable which is not defined.
Does anyone have any idea what's going wrong here?
Many Thanks,
Hassam
var abc = "11:00, 11:10, 12:20,12:30";
var split = abc.split(",")
var limits = new Array();
var alltimes = [[],[]];
//var split = ["11:00", "11:10", "12:20","12:30"];
var x = 0;
for (var i = 0; i < split.length -1 ; i++) {
limits.push(split[i]);
// alert(split.length );
if(i%2 === 1) // If odd value
{
alert(limits);
for (var j = 0;j<2; j++)
{
// alert(limits[j]);
alltimes[x][j] = limits[j];
}
limits.length = 0;
x++;
}
// alert(split.length + 2);
//
}
alert(alltimes);
// console.log(abc)
This is my JavaScript code
$(document).ready(function(){
$('.timepicker').click(function(){
var ajaxurl = 'Ajax.php',
data = {'action': 'Hassam'};
$.post(ajaxurl, data, function (response) {
// $('#timepicker').timepicker('option', 'disableTimeRanges', [abc]);
var split = response.split(",");
var x = 0;
for (var i = 0; i < split.length -1 ; i++) {
limits.push(split[i]);
alert(split.length );
if(i%2 === 1) // If odd value
{
for (var j = 0;j<2; j++)
{
// alert(limits[j]);
alltimes[x][j] = limits[j];
}
limits.length = 0;
x++;
}
alert(split.length + 2);
//
}
alert(alltimes);
// console.log(abc)
});
There is very simple solution to achieve what you want.
var split = ["11:00", "11:10", "12:20", "12:30"];
var alltimes = [];
while (split.length) {
alltimes.push(split.splice(0, 2));
}
console.log(alltimes);
I'm writing a program in JS for checking equal angles in GeoGebra.
This is my first JS code, I used c# formerly for game programming.
The code is:
var names = ggbApplet.getAllObjectNames();
var lines = new Set();
var angles = new Set();
var groups = new Set();
for(var i=0; i<names.length; i++)
{
if(getObjectType(names[i].e)==="line")
{
lines.add(names[i]);
}
}
for(var i=0;i<lines.size;i++)
{
for(var j=0;j<i;j++)
{
var angle = new Angle(i,j);
angles.add(angle);
}
}
for(var i=0;i<angles.size;i++)
{
var thisVal = angles.get(i).value;
var placed = false;
for(var j=0;j<groups.size;j++)
{
if(groups.get(j).get(0).value===thisVal)
{
groups.get(j).add(angles.get(i));
placed = true;
}
}
if(!placed)
{
var newGroup = new Set();
newGroup.add(angles.get(i));
groups.add(newGroup);
}
}
for(var i=0;i<groups.size;i++)
{
var list="";
for(var j=0;j<groups.get(i).size;j++)
{
list = list+groups.get(i).get(j).name;
if(j != groups.get(i).size-1)
{
list = list+",";
}
}
var comm1 = "Checkbox[angle_{"+groups.get(i).get(0).value+"},{"+list+"}]";
ggbApplet.evalCommand(comm1);
var comm2 = "SetValue[angle_{"+groups.get(i).get(0).value+"}+,0]";
ggbApplet.evalCommand(comm2);
}
(function Angle (i, j)
{
this.lineA = lines.get(i);
this.lineB = lines.get(j);
this.name = "angleA_"+i+"B_"+j;
var comm3 = "angleA_"+i+"B_"+j+" = Angle["+this.lineA+","+this.lineB+"]";
ggbApplet.evalCommand(comm3);
var val = ggbApplet.getValue(this.name);
if(val>180)
{val = val-180}
this.value = val;
ggbApplet.setVisible(name,false)
});
function Set {
var elm;
this.elements=elm;
this.size=0;
}
Set.prototype.get = new function(index)
{
return this.elements[index];
}
Set.prototype.add = new function(object)
{
this.elements[this.size]=object;
this.size = this.size+1;
}
It turned out that GeoGebra does not recognize Sets so I tried to make a Set function.
Basically it collects all lines into a set, calculates the angles between them, groups them and makes checkboxes to trigger visuals.
the GeoGebra functions can be called via ggbApplet and the original Workspace commands via ggbApplet.evalCommand(String) and the Workspace commands I used are the basic Checkbox, SetValue and Angle commands.
The syntax for GeoGebra commands are:
Checkbox[ <Caption>, <List> ]
SetValue[ <Boolean|Checkbox>, <0|1> ]
Angle[ <Line>, <Line> ]
Thank you for your help!
In short, the syntax error you're running to is because of these lines of code:
function Set {
and after fixing this, new function(index) / new function(object) will also cause problems.
This isn't valid JS, you're likely looking for this:
function Set() {
this.elements = [];
this.size = 0;
}
Set.prototype.get = function(index) {
return this.elements[index];
};
Set.prototype.add = function(object) {
this.elements[this.size] = object;
this.size = this.size + 1;
};
Notice no new before each function as well.
I'm not sure what you're trying to accomplish by creating this Set object though - it looks like a wrapper for holding an array and its size, similar to how something might be implemented in C. In JavaScript, arrays can be mutated freely without worrying about memory.
Here's an untested refactor that removes the use of Set in favour of native JavaScript capabilities (mostly mutable arrays):
var names = ggbApplet.getAllObjectNames();
var lines = [];
var angles = [];
var groups = [];
for (var i = 0; i < names.length; i++) {
if (getObjectType(names[i].e) === "line") {
lines.push(names[i]);
}
}
for (var i = 0; i < lines.length; i++) {
for (var j = 0; j < i; j++) {
angles.push(new Angle(i, j));
}
}
for (var i = 0; i < angles.length; i++) {
var thisVal = angles[i].value;
var placed = false;
for (var j = 0; j < groups.length; j++) {
if (groups[j][0].value === thisVal) {
groups[j].push(angles[i]);
placed = true;
}
}
if (!placed) {
groups.push([angles[i]]);
}
}
for (var i = 0; i < groups.length; i++) {
var list = "";
for (var j = 0; j < groups[i].length; j++) {
list += groups[i][j].name;
if (j != groups[i].length - 1) {
list += ",";
}
}
var comm1 = "Checkbox[angle_{" + groups[i][0].value + "},{" + list + "}]";
ggbApplet.evalCommand(comm1);
var comm2 = "SetValue[angle_{" + groups[i][0].value + "}+,0]";
ggbApplet.evalCommand(comm2);
}
function Angle(i, j) {
this.name = "angleA_" + i + "B_" + j;
var comm3 = "angleA_" + i + "B_" + j + " = Angle[" + lines[i] + "," + lines[j] + "]";
ggbApplet.evalCommand(comm3);
var val = ggbApplet.getValue(this.name);
if (val > 180) {
val -= 180;
}
this.value = val;
ggbApplet.setVisible(name, false);
}
Hopefully this helps!
Your function definition is missing the parameter list after the function name.
Also, you're initializing the elements property to an undefined value. You need to initialize it to an empty array, so that the add method can set elements of it.
function Set() {
this.elements=[];
this.size=0;
}
I have a call:
var serve = function(teacher, callback) {
RE.createFakeMemberData(function(err, avgMember) {
//omitted
});
};
inside the createFakeMemberData, if I try to instantiate a mongoose model:
var statistic = new Statistic();
I get the error with the stack trace:
D:\Orkun\workspace\teb\tebesir-repo\scripts\engines\ResetEngine.js:61
var statistic = new Statistic();
^
TypeError: object is not a function

I think the 'this' is going out of scope or sth. I have also tried using bind..
RE.createFakeMemberData(function(err, avgMember) {

no joy..
