Unable to access ng-model values within ng-repeat loop

I'm having trouble setting ng-model values within an ng-repeat statement.

When I repeat this div with an array of JSON objects, I am able to print the 'ID' value of the object in any element. However, I can't use that as the ng-model value for the checkbox inside. I must be making a mistake somewhere. Any suggestions on what that might be?

I would greatly appreciate it if someone could take a look and offer some guidance.

For reference, here is a link to a codepen showcasing the issue: Code pen link

Answer №1

When assigning a value to a checkbox model, it is typically boolean, representing true or false, unless specified otherwise. This allows for only two options.

Instead of using 'id' as the model attribute, consider using another attribute that can store a boolean value. For example, why not use 'isSelected'?

<div ng-controller="quoteController" ng-app="MyApp" class="benefits-container">
    <!-- benefits -->
      <div class="benefit" ng-class="{'selected': pe.id}" ng-repeat="pe in policyEnhancementsArr | filter: {type:'optional'}">
          <div class="top">
              <md-checkbox ng-model="pe.isSelected" class="blue"></md-checkbox>
              <h5 class="item">{{pe.name}}</h5>
              <h5 class="prize">{{pe.loading}}</h5>
          </div>
          <div class="bottom">
              <p>{{pe.limitDisplay}}</p>
          </div>
      </div>
  </div>

Then update the 'isSelected' value:

...
{
  "id": "PVC022",
  "name": "NCD Protector",
  "limit": null,
  "limitDisplay": "N/A",
  "desc": "<TBC>",
  "type": "optional",
  "loading": 0.0,
  "isSelected": true
},
...

I just completed writing code that is very similar, except for the filter you used with ng-bind. I recommend checking out the article where they suggest utilizing ng-value.

Answer №3

Try implementing ng-repeat and ng-model in the same line for a more efficient code structure.

Here is an example of what you can do:

<div class="benefit" ng-class="{'selected': pe.id}" ng-repeat="pe in policyEnhancementsArr | filter: {type:'optional'}">
          <div class="top">
              <md-checkbox ng-model="pe.id" class="blue"></md-checkbox>

Instead of the above, try this approach:

<div class="benefit" ng-class="{'selected': pe.id}" ng-repeat="pe in policyEnhancementsArr | filter: {type:'optional'}" 
ng-model="pe.id">
              <div class="top">
                  <md-checkbox  class="blue"></md-checkbox>
