New line in express.js message

问题

Is it possible to make a new line in the message notification?

"\n" or "\r\n" just disappear but there's no new line set. I also tried var endOfLine = require('os').EOL; instead of \n. Doesn't work sadly.

res.render('settings.ejs', {
        user: req.user,
        isAuthenticated: true,
        message: 'Changed User(s):' + changearray + '\n(Notice: You can\'t affect Users with higher Settingrights.)'
        });

Probabbly a stupid/easy question but I don't get it working... Thanks in advance.

You can use html tags. The reason why they are not getting displayed is because I suppose you must be using escaped text. You need to use the unescaped syntax if you want to render the tags in your html string:

res.render('settings.ejs', {
        user: req.user,
        isAuthenticated: true,
        message: 'Changed User(s):' + changearray + '<br />(Notice: You can\'t affect Users with higher Settingrights.)'
        });

Here's how to display unescaped text in your view:

<%- message %>
