我想使javascript库功能不起作用

Question

I wanted to call the run function that should call the other and action will be done on the base of element_id

 NGL = {}
NGL.SceneBuilder = function() {

  var yamlFile = 'http://example.com/main.yaml'
  var parseYaml = function() {
  }
  var buildScene = function() {
    // other code

    simulationStarted(element_id);
  }

  return {
    run: function(element_id) {
      parseYaml();
      buildScene(element_id);

    }
  }

}
NGL.SceneBuilder.run('#someid');

Answer 1

You're not executing your factory so NGL.SceneBuilder is a function, not an object having the run property. Call the function :

NGL.SceneBuilder = (function() {

  ...

})(); // <<===

Note also that you forget to declare the element_id parameter in buildScene but maybe is it just for the question.
