Re: [Haskell-beginners] Options for creating a multiple select form via Yesod

The best way for code contributions in general is to submit a pull request on Github. If that's a problem, sending a patch via email works as well (either directly to me or to web-devel). Michael On Sat, Jun 11, 2011 at 1:14 AM, Michael Litchard wrote:

Hey! I just added multiSelectField to the Forms library. I'm only getting the first value selected, but I think that's because of how I'm using multiSelecrField. I'm going to try to change the client code to fix this. I'll let you know how it goes. when I get a maybeMultiSelectField added I'll show you what I have. What would be the best way to submit this?

Hi Michael,

There's nothing jQuery or Javascript specific about a multi-select field: it's just a normal select field with a "multiple" attribute. I would recommend taking the selectField code from yesod-form and modifying it to be multi-select. I'll likely do this myself eventually, but it could be a good learning experience in Yesod (and a great introduction to contributing to the framework if you're so inclined).

I'm trying to create a multiple select form, as illustrated on the following: http://api.jquery.com/selected-selector/

Here's the options I see possible:

(1) Write a jQuery widget. (2) Use plain javascript via Julius (3) Use the low-level functions in Yesod.Form to write a widget (4) Use a pre-existing function that does what I need, but am not aware of this functionality

(1) has appeal as it looks like something small I can contribute to the project. It will take me some extra time to figure out the details. But, I had a look at the other jQuery widgets and they seem to provide an approachable model to follow.

(2) This looks like the most straight-forward approach. I'm just learning javascript so would have to figure out how to capture values in Haskell from the form.

(3) This looks like the most difficult way. I don't think I know enough about the low-level functions in Yesod.Form to be able to accomplish this in a timely manner.

(4) This is the best scenario. There's already a way to do this right now, and I just haven't identified it. If this is the case, I would appreciate being pointed in the right direction.

Until informed otherwise, I'm evaluating options 1 and 2. All feedback welcomed. Thanks to all who made Yesod possible.
