capture client events in seaside?
Locked
 
|
Hi what is the best way to capture a client-side event in seaside?
I have a menu that includes a select box. I would like to capture the select event so that I can update a view when the selection changes.
html select list: (Dao new) allProducts; callback: [ :value | productEntryAction value].
I guess I could wrap it in a form and put a 'go' submitButton next to it, but that seems so 2004 ;) Is there anything better? _______________________________________________ seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

html select list
onChange: (html jQuery ajax callback: [ do your stuff here ]).

thanks. I had a feeling it involved jquery or javascript; This looks much scary than I was expecting. ;)

hmm. I tried your suggestion and it's almost working, but I don't see how to get the current selection value back. If I replace the [do your stuff here] block with one that accepts an argument, like [:val | doSomethingWIth: val] I get an exception stating that the block wants an argument, but it's not being called with one.
I tried to use html select callback: to get the selected value (this seems to be what the example on the Jquery/seaside web pages show), but it never gets invoked:
html select
list: Dao new allProducts; selected: currentProduct; callback: [ :value | currentProduct := value ];
onChange: (html jQuery ajax callback: [ productEntryAction value: currentProduct]).
Any other suggestions would be appreciated. Thanks again. On Sun, Sep 11, 2011 at 2:46 PM, Milan Mimica <[hidden email]> wrote: html select list _______________________________________________ seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

| selectId | You could try something like (untested): html select id: (selectId := html nextId); list: Dao new allProducts;
selected: currentProduct; callback: [ :value | currentProduct := value ]; onChange: (html jQuery ajax script: [ :s |
s << "render updates here"]; serialize: (html jQuery id: selectId)) On 13 September 2011 14:18, Larry White <[hidden email]> wrote: hmm.

The callback won't be executed until the select element is serialized (either via ajax or submission), so in order to get the currently selected value, you will need to serialize first.

There's a very nice, but deprecated, method on WASelectTag called beSubmitOnChange that does exactly what I wanted. Having to explicitly serialize the selected text and lookup the text on the server seems like a tiny step backwards.
