piteto

@piteto

Feel free to ask your question here @Pickorita plenty willing to help. If it's a lot of code, put it in a codepen or jsfiddle

Nickey Pickorita

@Pickorita

I can't put it in codepen

its quite large and in dreamweaver

There are just 3 elements that I need to align but I think I messed up something so its just aligning wrongly

    "5439": {

    }
};
// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));

// Only change code below this line
function updateRecords(id, prop, value) { 
  if (value=="") {
    delete collection[id][prop];
    return collection;
  }
  switch(prop) {
    case "tracks":
      if (collection.hasOwnProperty(prop)) {
        collection[id][prop].push(value);
      }
      else {collection[id][prop]= [value];}
      break;     
    default:
      collection[id][prop] = value;      
             }

  return collection.hasOwnProperty(prop);
}

// Alter values below to test your code
console.log(updateRecords(2468, "tracks", "Free"));

guys why is it returning false

when it obv should return true because 2468 has a property called tracks

no need to look at the whole code, just tell me why the returned boolean is false

Hi! Does anyone here use UI Router? I have a problem with my code, been trying to find other solutions for about an hour now, help is pretty much appreciated!
Here's my HTML base:

<ul class="formSteps uk-margin-large-top">
            <li ui-sref-active="active">
                <a ui-sref=".substep" class="removeLink">Basic Information</a>
            </li>
            <li ui-sref-active="active">
                <a ui-sref=".step_four" class="removeLink">Business Information</a>
            </li>
            <li ui-sref-active="active">
                <a ui-sref=".step_five" class="removeLink">Business Activity</a>
            </li>
            <li>
                <a class="removeLink">Documents</a>
            </li>
            <li>
                <a class="removeLink">Gallery</a>
            </li>
            <li>
                <a class="removeLink">Employee</a>
            </li>
            <li>
                Complete
            </li>
        </ul>

        <!-- Substeps for step1 go here -->
        <div ui-view="substep"></div>

<div class="br-form-container">
            <div class="page-header text-center">
                <!-- Our nested state views will be injected here -->
                <div ui-view></div>
            </div>
        </div>

Here's my route.js:

// Adding state for substeps
            .state('business_registration.substep', {
                url: '/1-sub',
                data: { activeTab: 'business'},
                controller: 'AccountBusinessController',
                params: {
                    businessType: null
                },
                controllerAs: 'abc',
                views: {
                    '': {
                        templateUrl: 'business/step1.html'
                    },
                    'substep@business_registration.substep': {
                        templateUrl: 'business/substep.html'
                    }
                }
            })

What I'm trying to do is to have 2 separate step progress counter, where the substep consists of substeps for different views, but it doesn't show up in the page.

var x = 0;

x += 1.01;
x += 2.05;

console.log(x);

//why does this equal 3.0599999999999996
//and not 3,06???
