RIOT.JS - Loops

We can iterate through RIOT array of primitives or of Objects and create/update the html elements on the go. Using "each" construct we can achieve it.

  • Create array − Create an array of object.

this.cities = [
   { city : "Shanghai" , country:"China" , done: true },
   { city : "Seoul"    , country:"South Korea" },
   { city : "Moscow"   , country:"Russia"      }
];

  • Add each attribute − Now use the "each" attribute.

<ul>
   <li each = { cities } ></li>
</ul>

  • Iterate array of objects − Iterate the array using object properties.

<input type = "checkbox" checked = { done }> { city } - { country }

Example

Following is the complete example.

custom7Tag.tag

<custom7Tag>
   <style>
      ul {
         list-style-type: none;
      }
   </style>
   <ul>
      <li each = { cities } >
         <input type = "checkbox" checked = { done }> { city } - { country }
      </li>
   </ul>
   <script>
      this.cities = [
         { city : "Shanghai" , country:"China" , done: true },
         { city : "Seoul"    , country:"South Korea" },
         { city : "Moscow"   , country:"Russia"      }
      ]; 
   </script>
</custom7Tag>
