Why isn't the Angular expression being evaluated during runtime?

Exploring Angular and encountering an issue.

This is my HTML code:

<ul class="board-list gutter js-board-list clearfix">

   <li class="" ng-repeat="board in boardsUserOwns.success.boards">
        <a class="js-open-board highlight-icon    unknown" ng-click="getBoardDetails('{{board[0]}}')" href="" style="  background-color: #0E74AF; ">
        <span class="thumbnail" style=" ; background-color: #0E74AF; "></span>
        <span class="fade"></span>
        <span class="board-list-item-name" title="Geneva">{{board[0]}}</span>
        </a>
   </li>
<ul>

The specific line in question:

<a class="js-open-board highlight-icon    unknown" ng-click="getBoardDetails('{{board[0]}}')" href="" style="  background-color: #0E74AF; ">

contains the Angular JS expression {{board[0]}}.

After loading the page, the console displays this output:

<a class="js-open-board highlight-icon    unknown" ng-click="getBoardDetails('userwithbelongsto1')" href="" style="  background-color: #0E74AF; ">

which functions correctly.

However, upon clicking the a tag, the controller logs the unevaluated Angular code:

$scope.getBoardDetails = function(boardName)
{
   console.log("The board name is " + boardName)
}

In the console, it shows:

 The board name is {{board[0]}}

Feeling confused about where I might be going wrong.

Appreciate any guidance provided.

Answer №1

Try using `getBoardDetails(board[0])` without the curly braces.

The reason behind seeing `{{board[0]}}` printed in the console is because that string is being passed as the boardName argument to the function. In your current setup, calling `getBoardDetails('{{board[0]}}')` means invoking the function with the string `{{board[0]}}`. However, when the HTML is parsed, it correctly replaces that expression.

Answer №2

When a grid element is clicked, I need to show individual boards. The board_id is retrieved from the database. What should be my next step? Figure URL: https://i.sstatic.net/x0Sn2.png

app.config(['$stateProvider', function($stateProvider) {

  $stateProvider
  .state('board.boardDescription', {
      url: '/:bid',
      templateUrl:'js/main/templates/board.html'
    })
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<ul class="board-list gutter js-board-list clearfix" >
                    <li ng-repeat="board in boardName">
                     <a ui-sref="board.boardDescription({bid:board._id})" class="js-open-board highlight-icon" style="background-color: #0066A1;">
                       <span class="details">
                          <span class="board-list-item-name">{{board.name}}</span>
                        </span>
                      </a>
                    </li>
                  </ul>
