Putting a print button on my page - "Add helpers to snapshot and pass objects in request parameters"

[riley]

I have been doing the research on putting a print button that will take the contents of my page - a simple HTML table - maybe open up a popup or a dialog and printing the contents of the page on pressing the button.]

What is the fastest way to do this?

My research led me to these links below:

1) https://groups.google.com/forum/#!topic/liftweb/Q_7vTMgEJbw

2) https://groups.google.com/d/topic/liftweb/vPkJ9m0SqlI/discussion

3) http://www.assembla.com/spaces/liftweb/tickets/978-add-helpers-to-snapshot-and-pass-objects-in-request-parameters

Finally I access this: https://app.assembla.com/spaces/liftweb/tickets/978-add-helpers-to-snapshot-and-pass-objects-in-request-parameters/details

and I click on the below link to see what is at the other end of the link, 

(In revision:614098d4098bd6ce89e529f8638e877b440be92c) Closes #978. Added snapshot capability to RequestVar and allow RequestVar to be put in groups and snapshotted as a group

I created an Assembla account just to access this, but I get a Not Permitted page,

Anyway. I wanted to know jhow #978 was closed and where in the Lift source I can find the implementation that solves the original OP's question of putting a print button, which happens to be exactly what I want also.

thanks for your time

You can use `SHtml.link` to build a link that runs a function that sets the

request var appropriately.

A quick example:

val myEntity = currentEntity.is

"a [href]" #> SHtml.link("/url/to/thing", () => currentEntity(myEntity), _)

This will point to /url/to/thing, but append a query parameter that will

ensure that `currentEntity` gets set to its previous value.

The flip side of this is I would suggest trying to structure your URL

such that this isn't necessary, perhaps by having `/entity/id` and using

a Menu.param to look up the appropriate object.

But, if that won't work, SHtml.link should!

Thanks,
