I pass a variable title to my html document and access it there like this:

<h2><%= title %></h2> 

How can I access the same variable inside the <script> tag? I tried the following but it gives me an error:

<script>
    console.log(title);
</script>

Uncaught ReferenceError: title is not defined

Is this because the variable is in a different scope?

EDIT: I wanted to keep things simple in this post but based on the answers I realize that I should have mentioned that I use an external file for my script:

<script src="/javascripts/script.js"></script>

In this script I use jQuery for some stuff and I need the variable titlethere.

You can't access template variables in rendered output due to the nature of templates. However, you could render a javascript variable of the same name that is set to the literal value of the template variable. For example:

  • Are you using ejs templates?
  • Yes, that's correct.
  • Thanks, but it is not quite what I need. I thought stuff inside the tag would be evaluated the same way as if I did it in an external file. Your solution does not work in my external file: Uncaught SyntaxError: Unexpected token <
  • Why can't you place the suggested template partial before your <script src="/javascripts/script.js"></script>? Then your /javascripts/script.js should have access to title just fine due to (global) scoping (assuming that you're rendering the output that contains <script src="/javascripts/script.js"></script> and it's not from a static file being served).
  • I tried this, but it does not compile there either.
  • What does "it does not compile" mean?
  • My editor says expression expected and if I run it anyways it says in the console: Uncaught SyntaxError: Unexpected token <
  • This does not compile for me :(
  • Read the accepted answer here. Depending upon how you've configued express/ejs you may need to approach it differently.
