@FlintMayers - I think that a problem could be that you are looping through args.length, and it could be that the element that you are looking at first might be somewhere in the list but you aren't seeing it right away. You need to be able to look at the entire args list within your function before determining that the element is or isn't there. Using something like .indexOf() that gives you the answer in one shot is probably more efficient for this?

does anybody have any idea why self and social media appear in blue?

Ken Haduch

@khaduch

@Rubenricardo - because they are anchor elements (links) and that is the default color.

@FlintMayers

@khaduch You mean using indexof inside the for loop in the destroy function? or I don't need the for loop at all this way?

MaxLAB

@Max-LAB

@FlintMayers it is because for loop checks only first array member and that is 2. for loop initialise every time new element came in.

Ken Haduch

@khaduch

@Rubenricardo - you can override that, using CSS. Also, you have a typo on one of your attributes for the socialmedia link - hrer instead of href

@FlintMayers - use indexOf instead of a for loop - because you don't need to do both.

@FlintMayers

@khaduch How would I pass the whole args array inside the indexOf?

Ken Haduch

@khaduch

@FlintMayers - since it is in scope, you can just reference it, but if you look at the filter method, you can pass an optional argument that can be referenced via the this variable within the function. You could try it that way.

@Rubenricardo - you're welcome

Martynas

@FlintMayers

@khaduch

function destroy(element){
     if(element.indexOf(args) != 1){
        return element;
     }
  }

IGives me an error

@khaduch why i can't check it like that?

@khaduch I know I am passing in the whole array. I just don't know how to loop throug it without a for loop

Ken Haduch

@khaduch

@FlintMayers - where you have the element you have to have args instead - because .indexOf is an Array method, so your variable has to be an array.

Ritvars

@RitvarsZ

@adamgithub92 kts easy in css

Ken Haduch

@khaduch

so args.indexOf(element) is what you want, and you can just (or should just) pass the result of the comparison back, so you should try return args.indexOf(element) == -1;

Martynas

@FlintMayers

@khaduch changed it. But know it does the opposite of what is asked of me

@khaduch it filters out the wrong values


function destroyer(arr) {
  // Remove all the values
  var args = [];
  for(var i = 1; i < arguments.length; i++){
    args.push(arguments[i]);
  }

  function destroy(element){
     if(args.indexOf(element) != -1){
        return element;
     }
  }


  return arr.filter(destroy);
}

destroyer([3, 5, 1, 2, 2], 2, 3, 5);

@DarylKnapp

Hey @jdtdesigns are you still in here at all?

Martynas

@FlintMayers

@khaduch returns 3,5,2,2 while it should only return 1

Ritvars

@RitvarsZ

@adamgithub92 just do `element:hover{ backround-color: color;}

Ken Haduch

@khaduch

@FlintMayers - instead of doing !=, do === --- so you are testing the opposite sense of the value

@FlintMayers - oh, and double check what I posted here: :point_up: January 16, 2017 10:43 AM

you don't want to return the element, but the result of the .indexOf lookup...

Martynas

@FlintMayers

@khaduch thanks. it's solved now but i didn't quite get it

MaxLAB

@Max-LAB

@adamgithub92 as @RitvarsZ mention, you could

.result-item:hover{
    background-color: red;
}

Ken Haduch

@khaduch

@FlintMayers - take a few minutes to study what is going on - re-read the .filter() documentation and if you have further questions, just post them!

@RitvarsZ @Max-LAB yeah, i figured and tried that, but did't work

Muhammad Hasham

@MuhammadHasham23

https://codepen.io/Mohammad_Hasham/pen/JbWOWw?editors=1010

actually i am comparing user generated pattern with computer generated pattern and storing them in an array for comparison.The problem is in the compareArray function might be some logic mistake.

@khaduch

@ajayt365 - I had one that I started, not sure if it's the best, but here's a link: http://tutorialzine.com/2016/01/learn-sass-in-15-minutes/

@MohammadHasham - I'll give it a shot...

Muhammad Hasham

@MuhammadHasham23

@khaduch

MaxLAB

@Max-LAB

@adamgithub92 I tried on your pen, and it worked. If desired behavior is to change background color when hover returned result item

What is wrong with this API call?

$(document).ready(function(){
  var url = 'http://api.wunderground.com/api/myKey/geolookup/conditions/forecast/q/Canada/Toronto.json';
  $.getJSON(url,function(data){
    var request = JSON.parse(data);
    console.log(request[0]);
  });
})

Nothing logs to the console.
