有条件地显示EJS数据

Question

I am trying to reuse aa view in EJS. It just creates a list of the results of a database query. My code is

   <ul data-role="listview" data-theme="a">
    <% for(var i=0; i<records.length; i++) { %>
        <li><a href="#actions" onClick="SetCurrentCustomer(<%= records[i].ID %>)">
PROBLEM HERE---->    <%= records[i].Name %> <%= records[i].TOJ%></a></li>
    <% } %>
    </ul>

I would only like to show each records[i].Name and records[i].TOJ if they are defined or if the view is called from a certain route or whatever is easier. I have tried inserting a function to filter, but it just got ignored. How can i do this?

Like for , you can also use if in EJS:

<% if (someCondition) { %>
  <%= records[i].Name %> <%= records[i].TOJ %>
<% }; %>

Or, if you just want to prevent undefined being shown when a property isn't defined, you can use this:

<%= records[i].Name || '' %> <%= records[i].TOJ || '' %>

(be aware that this would fail for properties containing the number 0 or a boolean false )
