Ways to pass Angular variables to JavaScript while utilizing the $scope() function

This is my process for receiving input: extracting data from an sql table, passing it through php slim, integrating it into angularjs, and displaying it on a website.

I am looking to retrieve a variable in javascript that has been passed from php slim to angular.

Currently, I have the following code inside $( document ).ready(function() {:

var $element = $('div[ng-show="game"]');
var scope = angular.element($element).scope();
console.log(scope);

When executed, this code logs the scope object in the console.

Any suggestions on how to accomplish this task?

Answer №1

To implement a JQuery method in your Angular controller, simply define the method within the controller function.

//Controller
function myController($scope) {

    $scope.data = getDataFromServer();

    $scope.customMethod = function(){
       $('#someElement').html($scope.data.totalValue);
    }
}

Now you can easily invoke this method from your view using Angular directives.

//View
<div ng-controller="myController" ng-app>
   <div id="someElement"></div>
   <button ng-click="customMethod()">Click Me</button>
</div>

It is possible to pass data without using the scope method in Angular by following the steps outlined below. The process involves writing code within an Angular page for declaring, defining, and redefining variables, as well as incorporating some JavaScript.

A. Declaring and Defining Variables in Angular Page:

environmentStringify = {
'project_url':'172.23.77.82:4200/myangularproject/', 
'testMode':true
};
declare var environmentStringify: any;
environmentStringify = JSON.stringify(environment);

B. Writing Code in HTML Page:

<script type="text/javascript">
    var environmentStringify = "{{environmentStringify}}";
    var environment = null;

    function isJsonString(str) {
        try {
            JSON.parse(str);
        } catch (e) {
            return false;
        }
        return true;
    }

    function setJSEnvironmentVariable(){
        if(isJsonString(environmentStringify)){
            environment = JSON.parse(environmentStringify);
        } else {
            setTimeout(function(){
                setJSEnvironmentVariable();
            }, 500);
        }
    }

    setJSEnvironmentVariable();
  </script>
