[Seaside] Using the select tag

[Boris Popov, DeepCove Labs]

Olivier,

 

No, you have a way of separately providing display ‘labels’ for your actual objects in the list,

 

(html select)

list: self countries;

selected: country;

enabled: [:ea | ea notNil];

labels: [:ea | ea ifNil: ['---'] ifNotNil: [ea name]];

callback: [:value | country := value].

Hi Boris,

This means that I must analyze the choice of the user from the text that is displayed on the screen. ok :-( 

But how can I must doing if my application supports many languages ?

The framework will pass an actual 'selected' object from your 'list' into the callback, what it puts in the 'value' in the HTML should be completely irrelevant to you.

		Hi,
		 
		I need to use a drop-down menu in a seaside application. In the 
		examples that I have found, the displayed values are initialized with #list:
		 
		html  select
		        list:  #(#Male  #Female);
		        selected:  self  contact  gender;
		        callback:  [  :value  |
		                value  =  #Male
		                ifTrue:  [  self  contact  beMale  ]
		                ifFalse:  [  self  contact  beFemale  ]  ].
		 
		In the browser, I get this HTML code :
		 
		<select  name="3"><option  value="1"selected="selected">Male</option><option
		  value="2">Female</option></select>
		 
		My problem is how to set the values for each<option>  tag ? I would 
		get something like :

	Why do you want to do this?
	 
	Cheers
	Philippe
