How to learn the template?

[xyaw Li]

I try to modify the file :      /edx-platform/lms/templates/student_account/account_settings.underscore

I add the code in red . But it is not working . 

I would like to know :

  1.  What is the kind of the template grammar?( Python template? or others? )  ( I would like to learn and then I could modify my code )

  2. I could not find what's wrong with the code in red  . Do you have any suggestion ?

    <div class="account-settings-sections">
        <% _.each(accountSettingsTabs, function(tab) { %>
            <div id="<%- tab.name %>-tabpanel" class="account-settings-tabpanels <% if (!tab.class) { %> hidden <% } %>" aria-label="<%- tab.label %>" role="tabpanel"></div>
        <% }); %>
        <% if (tab.name === "nid_tab_name") { %>
            .......the code I want to do.........
        <% } %>
    </div>

EDX uses underscore js 

EDX has logs at edx/apps/edx/bin/log for each section. 

You probably know wether the html file you have belongs to CMS , LMS or both due to the folder structure and you can check what is going on exactly.

Tab.name is properly opened and closed, I am pretty sure the "role="tabpanel" is not properly closed as it should be  "role="tabpanel"" and it makes no sense to open double brackets within a double bracket field.

Consider using single brackets within double bracket fields  making it "role='tabpanel'" but this is barely a start on fixing what is wrong. 

The log has all the information you need.
