How to execute js with Jade?

问题

i was wondering how to execute js before rendering?

This fails

-#{somejs} // Outputs just the js-code
p #{somejs()} // Executes the js-code, but doenst render the html

// In EJS I just write. But how can i do this with node?

<%- somejs() %>

// I try to use express-messasges (https://github.com/visionmedia/express-messages) with Jade instead of ejs

回答1:

The following both work for me:

- var test = Math.sqrt(16);
  div #{test}

or

div #{Math.sqrt(25)}

If possible, would you please post your somejs()? Are you certain that it is producing a HTML string?

回答2:

To use express-messages with jade use this code in your template:

- var m = messages()
!= m

回答3:

In jade simply use - someJS() for more example see the jade website and the in the readme
