Using PUT to delete in Node.js

In node.js, I can use

app.route('/').get(getObjectList).post(postAddObject).put(putDeleteObject);

but I don't know how to trigger ...put(putDeleteObject) in html.

Is it true that we are limited to post and get in html? When can I then use put? Is it only for REST requests through, for instance, jQuery?

How do you normally delete objects? I think it is more safe to go through a post request rather than a get request, but it would be great to chain it like I did in the code example, however, it is probably not possible if the html cannot distinguish between post and put. I have seen some examples where they use

<form method="post">
  <input type='hidden' name='_method' value='put'>
  <button type='submit'>Delete</button>
</form>

but it doesn't work for me.

Edit

I meant to use DELETE and not PUT, but the problem stay the same. I don't know how to change my html to support the DELETE request.

You didn't include it in the question but it looks like you're using Express. In that case you can use:

var methodOverride = require('method-override')
app.use(methodOverride('_method'))

And then you'll be able to use HTML forms like this one:

<form method="POST" action="/your/resource?_method=DELETE">
  <button type="submit">Delete</button>
</form>

And this in your route handlers:

app.route('/')
  .get(getObjectList)
  .post(postAddObject)
  .put(putObject)
  .delete(deleteObject);

If you want to use:

<form method="POST">
  <input type="hidden" name="_method" value="delete">
  <button type="submit">Delete</button>
</form>

then it's a little bit more complicated but still possible - for more info see:
