Custom JavaScript Display and Grading
-------------------------------------
Custom JavaScript display and grading problems allow you to create your own learning tool
using HTML and other standard Internet languages and then add the tool directly
into Studio. When you use this problem type, Studio embeds your tool in an
inline frame (IFrame) so that your students can interact with it in the LMS. You can grade
your students' work using JavaScript and some basic Python, and the grading
is integrated into the edX grading system.
This problem type doesn't appear in the menu of advanced problems in Studio. To
create a JavaScript input problem type, you'll create a blank advanced problem,
and then enter your code into the component editor.

Create a Custom JavaScript Display and Grading Problem
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#. Create your JavaScript application, and then upload all files associated with
that application to the **Files & Uploads** page.
#. In the unit where you want to create the problem, click **Problem**
under **Add New Component**, and then click the **Advanced** tab.
#. Click **Custom JavaScript Display and Grading**.
#. In the component that appears, click **Edit**.
#. In the component editor, modify the example code according to your problem.
- If some elements of your problem are located in different places, you need to
bypass the same-origin policy (SOP). To do this, change **sop="false"**
in line 8 to **sop="true"**. For more information, see
`same-origin policy <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Same_origin_policy_for_JavaScript>`_.
#. Click the **Settings** tab.
#. Set **Maximum Attempts** to a number larger than zero.
#. Click **Save**.
To re-create the example problem above, follow these steps.
#. Go to :ref:`Appendix F` and use the code samples to create the following files.
- webGLDemo.html
- webGLDemo.js
- webGLDemo.css
- three.min.js
**Note** *If you need to bypass the SOP, you'll also create a jschannel.js file.*
#. On the **Files & Uploads** page, upload the files you just created.

.. note:: When you create a JavaScript Input problem, keep the following in mind.
- The webGLDemo.js file defines the three JavaScript functions (**WebGLDemo.getGrade**,
**WebGLDemo.getState**, and **WebGLDemo.setState**).
- The JavaScript input problem code uses **WebGLDemo.getGrade**, **WebGLDemo.getState**,
and **WebGLDemo.setState** to grade, save, or restore a problem. These functions must
be global in scope.
- **WebGLDemo.getState** and **WebGLDemo.setState** are optional. You only have to define
these functions if you want to conserve the state of the problem.
- **Width** and **height** represent the dimensions of the IFrame that holds the
application.
- When the problem opens, the cone and the cube are both blue, or "unselected." When
you click either shape once, the shape becomes yellow, or "selected." To unselect
the shape, click it again. Continue clicking the shape to select and unselect it.
- The response is graded as correct if the cone is selected (yellow) when the user
clicks **Check**.
- Clicking **Check** or **Save** registers the problem's current state.
