@YaroNew - just came back - in your post here: :point_up: October 27, 2016 10:20 PM it was really the ; at the end of the line for (var j=0; j< arr[i].length; j++); that was causing the problem. If you just removed that erroneous semicolon from the end of that for loop line, it would have worked fine, extra braces not necessary (but a good idea to have them for clarity.)

@khaduch thanks that's work, but how in earth the for loop knows its block end with out {}

@khaduch
@walidashri - if you do not open a block of code with {} braces, then the next single line of code will be the body of the for loop. In this case, having the ; there was essentially setting up a "null" code statement to execute. If that wasn't there, then the single line that performed the multiplication would be the for loop's body.
@walidashri - but if you read coding guidelines, they'll tell you not to do that single-line block, and use braces to make it clear where the code body begins and ends.

@walidashri
@khaduch so
for(whatever)
do some// gonna be executed 
do some 2 // won't be excuted?

@sharkantropo
Hello, anyone could help me to figure out a current issue I have with an intermediate frontEnd challenge
Ken Haduch
@khaduch
@walidashri - yes, the first do some would be executed the number of times that the for loop dictates, and the do some 2 would be executed after that loop finished, most likely only one time (unless it was another for loop, for example.)

@sharkantropo
@khaduch https://codepen.io/Sharkantropo/full/jrpbqX/ Alright, my Jquery code seems to work, but everytime I request to search wiki pages by putting the keyword and afterwards press enter, the page displays the results below but it autorefresh immediately and clean everything. ( nevermind the css and html, they are just there for staple)
Ken Haduch
@khaduch
@sharkantropo - are you using a <form for your page? Clicking the submit button on a form submits and reloads the page. You can put a method preventDefault() in your code to prevent the default action, which is to submit the page back to the server. There are other ways to do it, too - let me go check out your code page.
Ken Haduch
@khaduch

@sharkantropo - if you modify your code to add that line event.preventDefault(); in this place:

          if(event.which == 13)
               {
                  var searchTerm = $("#searchWord").val();
                  if (searchTerm !== "") {
                              ajaxAgent(searchTerm);
                            event.preventDefault();
                                  } 
                   else {

I believe that it will fix your problem.
(Pardon the sloppy indentation.)

sharkantropo
@sharkantropo
@khaduch No problem, I can understand it well enough. I'll add it right away.
@khaduch It worked, thanks !.

Hey guys, any ideas on why my background-image will not fill the entire div it is currently in? I am looking at ID: 'space_1_HeroSection_2'

http://codepen.io/vinarius/pen/XjELAK?editors=1100

it only displays the image as far as there is text
Ken Haduch
@khaduch
@vinarius - I'm not seeing an image at all - it is giving me a network error something to the effect of this: NetworkError: 403 Forbidden - https://photos-1.dropbox.com/t/2/AACQbonHAQBC7QYPL8rj0GTY7OQ2mrXltHocKAZTTvKUXA/12/342555477/jpeg/32x32/1/_/1/2/conference%20room.jpg/EPDI0tYCGMUCIAIoAg/dfk-NckShDZqECnhwWS11EMF2VxBylYCfc9JnMEiAug?size=2048x1536&size_mode=3" - I think that there is a different way to get the URL for a dropbox image? I mean for public sharing? I forget how to do that, but I was able to find something on the dropbox interface to get a URL for sharing?
Mark
@vinarius
hmmm
JD Tadlock
@jdtdesigns
use photobucket.com
Sorin Ruse
@sorinr
@vinarius i can see the img and its full width of the container. only you have applied that bg on a col-xs-3 div
Mark
@vinarius
@sorinr that's probably the mk design img. that's supposed to be that way. it's the conference room that im trying to fix.
Sorin Ruse
@sorinr
@vinarius you get a 403 forbidden response. recheck the url maybe something wrong there
Mark
@vinarius
ill ha ve to look into that
not sure why
ah
figured that out. had to replace www with dl
Sorin Ruse
@sorinr
@jdtdesigns just pm-ed you

i used the following code for settimeout

var timer;
$("#twitchSearch").on("input", function() {
    if (timer) { clearTimeout(timer); }
  $("#twitchDiv").empty();
    timer =  setTimeout(loadTwitch, 150);  
});

and the following code to set up loadtwitch (very little change in the beginning)

function loadTwitch(){  
  var search=$('input').val();

the result still the same with flashing, any way to improve?
this is my code: http://codepen.io/c0d0er/pen/RGLxpQ?editors=0010

Sorin Ruse
@sorinr
@vinarius and why do you camelcase classes and ids ?. in html and css these attributes are case insensitive
Mark
@vinarius
@sorinr that is incorrect information
they are case sensitive
c0d0er
@c0d0er
the flashing is when i input anything in the search field
Sorin Ruse
@sorinr
@vinarius sorry. u r right

hey guys, I need a bit of help. the basic layout for my site is this: boxes that link to something. then there are 2 links within those boxes that let you edit the object and delete the object. I had to use JavaScript to achieve this because it required Ajax. my problem is this: when I delete something I have it confirm that you want to delete that object. but if you hit cancel then it directs you to the object (because of the box's event listener). how can I stop this? here are the listeners:
var boxes = document.querySelectorAll('.filled.box');
for(var i = 0; i < boxes.length; i++){
    boxes[i].addEventListener('click', function(){
        window.location='/tips/' + findId(this);
    });
    boxes[i].querySelector('.edit').addEventListener('click', function(){
        window.location='/tips/' + findId(this.parentElement.parentElement) + '/edit';
    });
    boxes[i].querySelector('.destroy').addEventListener('click', function(){
        var id = findId(this.parentElement.parentElement);
        if(confirm("Are you sure?")){
            $.ajax({
                url: '/tips/' + id,
                type: 'DELETE',
                success: function(result) {
                    window.location='/tips';
                }
            });
        }
        else{
            window.location='/tips';
        }
    });
}

Hello! So I want to build a Simon Says App and I need some help. What I want is when I click start, after a time period the green button will turn white and then back to green after which JS will wait for the event where the user will press the green button. How do I write this in code?
$('.start').click(function(){
  setTimeout(function(){
  $('.btn-green').css("background-color","white");
   },1000);
});
