ng-if for older (1.0.X) angularjs versions

ng_if.js

angular.module('future', []).directive('ngIf', [function() {
  return {
    transclude: 'element',
    priority: 600,
    terminal: true,
    restrict: 'A',
    $$tlb: true,
    compile: function ($element, $attr, $transclude) {
      return function link($scope, $element, $attr, ctrl){
        var block, childScope;
        $scope.$watch($attr.ngIf, function ngIfWatchAction(value) {

          if (!!value) {
            if (!childScope) {
              childScope = $scope.$new();
              $transclude(childScope, function (clone) {
                clone[clone.length++] = document.createComment(' end ngIf: ' + $attr.ngIf + ' ');
                block = {
                  clone: clone
                };
                angular.element($element).after(clone);
              });
            }
          } else {

            if (childScope) {
              childScope.$destroy();
              childScope = null;
            }

            if (block) {
              angular.element(block.clone).remove();
              block = null;
            }
          }
        });
      };
    }
  };
}]);

Sorry but how to call ng-if in html??

Thanks.

very much appreciated, thank you

you can also wrap it into

if(angular.version.major === 1 && angular.version.minor === 0) {
   ... rest of the code ...
}
