changing the name of a variable within ng-include

Question

changing the name of a variable within ng-include

Here is some important HTML code:

<ng-include src="'app/views/order.html'"></ng-include>

Within the scope of this ng-include, there is a variable called trade. The structure of the trade variable is as follows:

var trade = {
    order: {}
}

The issue arises because the order.html file is expecting an order variable directly, not nested within trade.order.

How would you go about calling the ng-include and passing trade.order as the order variable?

Answer №1

ng-include accesses variables within the global scope, which is not recommended as it may cause issues.

Avoid using onload as it pollutes the global scope.

An alternative solution is to create a new directive that is more generic in nature

Here's how you can implement it:

<div ng-include-template="'app/views/order.html'" ng-include-variables="{ order: trade.order }"></div>

The directive code is as follows:

.directive(
  'ngIncludeTemplate'
  () ->
    {
      templateUrl: (elem, attrs) -> attrs.ngIncludeTemplate
      restrict: 'A'
      scope: {
        'ngIncludeVariables': '&'
      }
      link: (scope, elem, attrs) ->
        vars = scope.ngIncludeVariables()
        for key, value of vars
          scope[key] = value
    }
)

This directive avoids relying on the global scope by fetching and adding variables from the ng-include-variables object to its local scope.

I trust this explanation provides a cleaner and more versatile approach to handling variables.

To resolve this issue, you can implement a new directive:

angular.module('MyApp').directive('customTemplate', customDirective);

function customDirective() {
    return {
        templateUrl: function(element, attributes) {
            return attributes.customTemplate;
        },
        restrict: 'A',
        scope: {
            'templateVariables': '&'
        },
        link: function(scope, element, attributes) {
            var variables = scope.templateVariables();
            Object.keys(variables).forEach(function(key) {
                scope[key] = variables[key];
            });
        }
    };
}

Here is how you can use it:

<div custom-template="'myCustomTemplate.html'" template-variables="{ variable: 'myVariable' }"></div>

        }
    };
}
