Utilizing JSON Data in Angular Expressions for Dynamic Outputs

I have a PHP script that is returning this JSON data:

{
  "userData": {
    "userName": "knows_nothing",
    "userFullName": "Jon Snow",
    "userMoney": "124.01"
  }
}

Can anyone help me figure out how to access the variables (such as userName) in my webpage?

For example:

JavaScript

var app = angular.module('dashboard', []);
app.controller('userDataCtrl', function($scope, $http) {
    data = "{query:'userData'}"
    $.post("api/mysql.php", {query:'userData'})
    .then(function (response) {$scope.userData = response.userData;});
});

HTML

<div ng-app="dashboard">
    <div ng-controller="userDataCtrl">
        <h1> Username: {{ userData.userName }} </h1>
        <p> Balance: {{ userData.balance }} </p>
    </div>
</div>

I've been struggling with this for quite some time now.

Here's what it looks like when I `console.log(response.userData)

Object { userName: "knows_nothing", userFullName: "Jon Snow", userMoney: "124.01" }

Answer №1

As stated in the $http documentation, it is recommended to retrieve the response from response.data. Therefore, in this scenario:

...
.then(function (response) {$scope.userData = response.data.userData;});

will solve the issue.

Answer №2

It could be necessary to define the $scope.userData variable before using it inside the then-function.

Answer №3

Ensure to validate if your input is in array format. If it is indeed an array, you may need to implement the following logic: $scope.data = response[0].data.

If the issue persists, kindly provide the complete response structure for further assistance.
