• Javascript push() - undefined output

  I currently try to safe data of different users in an array using the push() function.
  Here is my current code:

  function data()
  {
  
      var information = [];
      var imgs = '';
      var percentage;
  
      var imgs = 'ABC';
      var percentage = '1';
  
      information.push({ imgs: imgs, chance: percentage });
  
      var imgs = 'DEF';
      var percentage = '2';
  
      information.push({ imgs: imgs, chance: percentage });
  
      console.log(information);
  
      information.forEach(function(deposit)
      {
          var deposit=deposit.imgs;
          var chance=deposit.chance;
  
          console.log(deposit);
          console.log(chance);
      });
  
  
  }
  

  This is the output of console.log(information):

  [ { imgs: 'ABC', chance: '1' }, { imgs: 'DEF', chance: '2' } ]
  

  And this is the output of information.forEach(function(deposit):

  ABC
  undefined
  DEF
  undefined
  

  At that's my problem. As you can see, it outputs the chance as undefined however it should output 1 and 2. Anyone know why it do that and know how I can fix it?
• Pymongo MapReduce as sum of subarray element

  I'm trying to perform MapReduce on this kind of data set:

   {
  "_id": "599861ce7ce78cd973746906",
  "name": "Macias Rosario",
  "col": [
    {
      "date": "15/03/2016",
      "name": "MAGNEATO",
      "amount": 313.86
    },
    {
      "date": "08/08/2016",
      "name": "FORTEAN",
      "amount": 151.06
    },
    {
      "date": "05/11/2014",
      "name": "ECRATIC",
      "amount": 291.68
    }
  ]
  

  }

  Goal is to sum up all amount for name Macias Rosario. Currently I did with my code to group all by subelements this.col.name on this way:

  mapper = Code("""
                             function() {   
                             for (var index = 0; index < this.col.length; ++index) {
                                  var col = this.col[index];
                                  emit(col.name, col.amount );
                              }   
                             }
                             """)
          reducer = Code("""
                             function(key, values) {
                                 var total =  0;
                                 for( var i = 0; i < values.length; ++i){
                                      total += values[i];
  
  
                                 }
                                 return value.price;
                             }
                 """)
          result = collection.map_reduce(mapper, reducer, "myresult")
  

  Has anyone have some idea how to reference, or group by this.name and not this.col.name because I don't know anymore and I'm driving nuts? PS don't suggest me to use aggregate, did that way, want to try on this way also :) Kind regards,
• How to fit JSON.parse into Promise.all?

  I got this code to retrieve a batch of matches from Riot Games League of Legends API:

  const matches = await Promise.all(matchlist.matches.map(function(match){
      return qRequest(server, "/match/v3/matches/" + match.gameId);
  }));
  

  The return value is a JSON formatted String. So matches ends up beeing an array of JSON Strings. I need the JSON parsed though, so that matches is an array of objects.

  I just can't wrap my head around how to fit JSON.parse in here?
• I'm trying to trigger the HTML5 color picker's popup with JQuery

  When an input[type=color] is clicked, a color picker opens in a popup window. I'd like to trigger this with JS.

  HTML

  <div id="customColorPick"></div>
  <input id="customColorPickInput" type="color" />
  

  JQuery

  $("#customColorPick").click(function() {
      $("#customColorPickInput").click();
  });
  

  Why does this not work?
• Decimal one place input type only number Ionic 3 latest version (3.9.2) I'm using

  I'm using ionic latest version 3.9.2. and I'm facing one problem. I have one input box. input type number, when user input in text box they allow only one digit after the decimal. and in input box maximum only one decimal allow not more than one.

  Examples: 
  1) 1407.1
  2) 6449496.8
  3) 1.1
  

  Like this only user can input one digit after decimal
• Q.all promise never runs then callback

  I am bit lost as to how Q.all works. I have the following code snippet (jsfiddle):

  function callUrl(remoteEndPoint){
    return $.ajax({
      url: remoteEndPoint,
      method: "GET",
      dataType: "json",
      contentType: "application/json; charset=utf-8",
      success: function (data) {
        console.dir(data);
      },
      error: function (xhr, textStatus, errorThrown) {
              console.error("error");
      }
    });
  }
  Q.all([callUrl("https://httpbin.org/get"), callUrl("https://httpbin.org/undefined")]).then(function(){
      console.log("Done");
  });
  

  The first call to callUrl will succeed, the second will fail (will return an error as the url does not exist). I am expecting the Q.all to execute the then callback like what ajax.always does but this isn't the case.

  Am I doing something wrong?
• onClick new input box add not working in angularJs. What to do?

• Changing routing location from a function

  So I want to change the routing location in AngularJS using $location.path within a function, but It doesn't work.

  app.controller('globalCtrl', function($scope, $route, $location){

   };
  
   $scope.changePath("/login");
  }
  

  How should I call the function or what should I do?
