Using AngularJS to Bind a $scope Variable

As I work on constructing a directive in angularJS, I come across an issue where I am attempting to bind an object property from another variable to an HTML element. Here is an example:

angular.module('ng.box', codeHive.angular.modules)
.directive('boxView', function($compile) {
return {
    link: function(scope, element, attrs, ngModelCtrl) {
       var name = 'exampl';
        var htmlTemplate = '<div instance="'+scope[name].innerVal +'"  </div> ';

        var el = angular.element('<div/>');
        el.append(htmlTemplate);
        $compile(el)(scope);
        element.append(el);
    },
  };
})

I am struggling to find a way to connect this object property to the instance attribute in the HTML element.

 var htmlTemplate = '<div instance="'+scope[name].innerVal +'"  </div> ';

If anyone has any suggestions or guidance on how to solve this problem, I would greatly appreciate it. Thank you!

Answer №1

It's quite straightforward:

let htmlTemplate = '<div component="' + name + '.innerVal"  </div> ';

By the way, these two lines ought to be switched around:

    element.append(el); // this should come first
    $compile(el)(scope); // this should come second

The rationale behind this adjustment is that directives in the appended template may require other directives on the parent elements which might not be accessible during offline compilation.
