Altering the content of a span within a list item using AngularJS

Recently, I encountered some HTML code that looks like this...

<ul id="sidemenu" class="wraplist wrapper-menu">
 <li class="auto" ng-class='{"active": active == 1 }' ng-click="makeActive(1)">
    <span class="arrow material-icons">arrow_down</span>
 <li>
 <li class="auto" ng-class='{"active": active == 2 }' ng-click="makeActive(2)">
    <span class="arrow material-icons">arrow_down</span>
 <li>
<ul>

Whenever ng-click=makeActive() is triggered, I aim to replace the text 'arrow_down' with 'arrow_right' for that specific < li> element only. Additionally, if the same element is clicked again, I want to switch it back to 'arrow_down'. The span text of all other < li> elements should remain unchanged. Is there a way to achieve this using AngularJS, potentially through angular.element? Or would another approach be more suitable?

Answer №1

When using keyboardArrow, it refers to only one variable. To handle this, you will need to create two separate scope variables: keyboardArrow1 and keyboardArrow2

<ul id="sidemenu" class="wraplist wrapper-menu">
     <li class="auto" ng-class='{"active": active == 1 }' ng-click="makeActive(1)">
        <span class="arrow material-icons">{{ keyboardArrow1 }}</span>
     <li>
     <li class="auto" ng-class='{"active": active == 2 }' ng-click="makeActive(2)">
        <span class="arrow material-icons">{{ keyboardArrow2 }}</span>
     <li>
<ul>

Update

To meet your specific requirements, I have created a customized example on Plunker.

Just updated my response based on our previous conversation in the comments section.

1) To start off, define keyboardArrow1 and keyboardArrow2 in your controller:

$scope.keyboardArrow1 = 'A';
$scope.keyboardArrow1 = 'B';

2) Next, you can showcase these values as follows:

<ul>
  <li ng-class="{'active': active == keyboardArrow1}" ng-click="makeActive(keyboardArrow1)">
    {{keyboardArrow1}}
  </li>
  <li ng-class="{'active': active == keyboardArrow2}" ng-click="makeActive(keyboardArrow2)">
    {{keyboardArrow2}}
  </li>
</ul>

Please take note that I have also made adjustments to the ng-class condition.

3) Lastly, when a <li> element is clicked, invoke the makeActive() function:

$scope.makeActive = function(arrow) {
    $scope.active = arrow;
}
