Lezione #id-jqmobile-2013-0014#

JQuery Mobile permete di nascondere dinamicamente le colonne di una tabella che riteniamo meno importanti.

Prima vedi il codice in azione! >

Poi vedi il codice, da notare:

<table data-role="table" id="table-column-toggle" data-mode="columntoggle" class="ui-responsive table-stroke">

data-role=”table” -> tabella
data-mode=”columntoggle” -> attivo selettore colonne
id=”table-column-toggle” -> id obbligatorio per associare la tabella al bottone che selezionerà le colonne
data-column-btn-text=”Columns to display…” Testo personalizzato per il bottone di selezione.
class=”ui-responsive table-stroke” Responsive con parametri di default di:

data-priority="1"
Displays the column at 320px (20em)
data-priority="2"
Displays the column at 480px (30em)
data-priority="3"
Displays the column at 640px (40em)
data-priority="4"
Displays the column at 800px (50em)
data-priority="5"
Displays the column at 960px (60em)
data-priority="6"
Displays the column at 1,120px (70em)

Priorità delle colonne:
data-priority=”1″ -> assegno la priorità

        <th>Senza attributi non posso essere rimossa</th>
	<th data-priority="1">Sono molto importante</th>
	<th data-priority="3">Sono mediamente importante</th>
	<th data-priority="5">Sono poco importante</th>
