将嵌套数组从node.js服务器传递到ejs页面

Question

I have this object:

 { id: 22, user: 'Username', born: '06/10/1975', ralationships: [ { profession: 'Joiner' }, { profession: 'Farmer' }, { company: 'Summer Sun Ranch', nickname: 'SunRanch' } ] } 

The above array is the output of a console.log(myArr[x]);

Then I pass it to ejs trough

  res.render('index', {
            lista: myArr
        });

The ejs index is this:

 <h1>Persone</h1> <ul> <% lista.forEach(function(elemento,i){ %> <li> <%= elemento.user %> </li> <ul> <% for (var j = 0; j < elemento[i].relationships.length; j++) {%> <li> <%= elemento[i].relationships[j] %> </li> <% } %> </ul> <% }) %> </ul> 

I am completely unable to handle the relationship sub-array in any way (the above code is just one of many try). The sub array seems missing.

Update: in the ejs I put this line

<%- JSON.stringify(elemento) %>

I receive back this: {"id":22,"user":"Username","born":"06/10/1975","relationships":[]}

This means that the relationships are passed empty from the node.js server What's wrong? Thanks a lot!

Answer 1

 lista.forEach(function(elemento,i){ 

So elemento is the object which has a user property and a ralationships property.

And i is the position that object olds in the lista array.

Thus:

 elemento[i].relationships 

… is nonsense: elemento is not lista .

You could use

elemento.relationships

or

lista[i].relationships

(You also need to spell ralationships (sic) consistently).

Answer 2

The problem was in the server.js. Thanks for the help.
