AngularJS is patiently waiting for the tag to be loaded into the DOM

I am trying to incorporate a Google chart using an Angular directive on a webpage and I want to add an attribute to the element that is created after it has loaded. What is the most effective way to ensure that the element exists before adding the attribute?

After exploring various sources, it seems like the directive I have should work but it's not functioning as expected:

.directive('vdfWidgetGoogleChart', ['$timeout', function ($timeout) {
return {
 restrict: 'E',
  //replace: true,
  templateUrl: 'widgetgooglechart.html',
  link: function ($scope, elem, attrs) {
      function addTabIndex () {
        elem.find('svg').attr({tabindex: -1});
      }
      $timeout(addTabIndex);
  },
  scope: {
    chartObject: '='
  }
}

javascript angularjs

Answer №1

When it comes to charting, my personal preference is to append attributes directly to the SVG element. This approach allows for a more angular process as opposed to searching for individual elements.

Another method is to create a controller and a directive specifically for the SVG element that relies on that controller. By structuring your code in this way, the svg directive should be triggered when an SVG element is a child of that directive. (Note: I have not personally tested this method)

<div controller-directive=".."><svg></svg></div>

In this setup, your code will recognize the SVG element once the controller is present as its parent.

Alternatively, you can modify your code to periodically check for the presence of the SVG element every 100ms until it is found.

function addTabIndex () {
    var svg = elem.find('svg');

    if (svg.length != 0)
        svg.attr({tabindex: -1});
    else
        $timeout(addTabIndex, 100);
}

$timeout(addTabIndex);
