Creating Interactive Radio Button Options in Angular

In my Angular project, I have a simple JavaScript function that retrieves data from an API and then converts it into radio buttons. Here is the code snippet:

function parseRoles(jsonObj) {
        console.log("passed: " + jsonObj);
        var tempRoleArray = [];
        for (var i = 0; i < jsonObj.role.length; i++) {
          tempRoleArray.push("<input type='radio' ng-model='user.role' value='" + jsonObj.role[i].role + "'>" + jsonObj.role[i].description + "&nbsp;");       
        }
        $("#userRoleEntry").html(tempRoleArray);
      }

While this works perfectly on the JavaScript side, I encounter issues on the Angular side where "user.role" or "$scope.user.role" is not recognized, resulting in "not defined" errors. Could this be due to some difference in the input within the partial? Or could there be other reasons behind this inconsistency? I've come across suggestions that Angular may not handle these scenarios well... EDIT: It's worth noting that this input is not the only one in the form. The rest of the inputs are either collected or returned from the API. Therefore, I'm unsure if compiling against the scope would be appropriate as it might be an overkill solution. However, I could be mistaken about this assumption.

Answer №1

It might be more beneficial to consider updating the API rather than incorporating $compile into your JavaScript code!

The ideal approach would involve having the API return the jsonObj, allowing you to effortlessly construct your View in Angular.

Performing tasks such as this is not aligned with Angular's best practices:

$("#userRoleEntry").html(tempRoleArray);

Based on my assumption, your JSON structure resembles an array of objects.

$scope.roles = [{role: 'test', description: 'text'}]; // representing your "jsonObj.role"

Consequently, your HTML implementation should resemble the following:

<div ng-repeat="obj in roles">
  <input type="radio" ng-model="user.role" ng-value="obj.role"> {{obj.description}}
</div>

Answer №2

In order for Angular to recognize the DOM element, you must first compile it.

Refer to the documentation for various examples: https://angular.io/api/core/Compiler

One approach suggested by @pankajparkar is to use

$compile($("#userRoleEntry"))($scope)
to compile the specified element.
