How do I send data to JSON''s property in jade(pug)?

Question

At first, I send data to Jade template in Nodejs.

app.get('/', function(req, res){ var arr = new Array( {firstname: 'Gil-dong', lastname: 'Hong'}, {firstname: 'Yeong-sil', lastname: 'Jang'} ); var jsonEncode = JSON.stringify(arr); var jsonDecode = JSON.parse(jsonEncode); res.render('/show', {arr: jsonDecode, prop: 'firstname'}); });

Next, I want to get 'prop' for arr's property.(in Jade template)

1)

div= arr[0].prop

2)

div= arr[0].#{prop}

3)

var p = !{JSON.stringify(prop)} div= arr[0].p

But nothing works. How can I send data to JSON's property?

You can use [] to access JavaScript Object property by a variable, so change your code to div= arr[0][prop]
