How to pass data from jade to mongodb using NodeJS as the server language

I'm using NodeJS, Express, MongoDB, Mongoose and jade for the web app. I am wondering how I pass data from jade to mongodb. The data that I want to pass are texts inside certain divs that are appended to the web page as users create them.

Example.

<div class="c1">
  <div class="c2">
    Object 1
  </div>

  <div class="c2">
    Object 2
  </div
</div>

I want to pass the text inside class c2 divs to mongodb. As of right now, I'm using 

a(href="/save/", value="Publish", class="button") Publish

But the problem is that after if I press this link, it will get redirected to localhost:3000/save/ but all the populated divs will not get transported, as they shouldn't because I'm not passing anything. I'm thinking I should have some sort of onclick function for the link. But then I don't know where to go from there.

How do your users edit the texts inside the divs? Are you using contentEditable? While that's a nice feature, it requires some work and knowledge of web development to implement that properly.

I'd suggest the simplest and "proper" way to do it, would be use textareas instead of the divs, and just submit them as a form:

<form action="/save/" method="post" class="c1">
  <textarea name="c2" class="c2">
    Object 1
  </textarea>

  <textarea name="c2" class="c2">
    Object 2
  </textarea>

  <input type="submit" value="Publish">
</form>
