Guardar orden despues de hacer Drag and Drop de divs Tengo un administrador de tareas el cual guarda en una base de datos las tareas que tiene cada uno pendiente con sus respectivas prioridades.
El problema es...
al momento de imprimir en pantalla las tareas pendientes lo hago usando unas librerias que encontre por la web, las cuales permiten hacer drag and drop de lo q esta en pantalla. Encontre el punto en el cual se suelta el mouse y ahi es donde deberia..
"tomar el orden de las tareas en pantalla una vez q se cambiaron de lugar" para modificar en la base de datos las nuevas prioridades.
Si alguien tiene una leve idea de como hacerlo se lo agradezco
Adjunto las tres librerias que usa para hacer el drag and drop.
Código PHP:
(function($) {
//If the UI scope is not available, add it
$.ui = $.ui || {};
//Add methods that are vital for all mouse interaction stuff (plugin registering)
$.extend($.ui, {
plugin: {
add: function(module, option, set) {
var proto = $.ui[module].prototype;
for(var i in set) {
proto.plugins[i] = proto.plugins[i] || [];
proto.plugins[i].push([option, set[i]]);
}
},
call: function(instance, name, arguments) {
var set = instance.plugins[name]; if(!set) return;
for (var i = 0; i < set.length; i++) {
if (instance.options[set[i][0]]) set[i][1].apply(instance.element, arguments);
}
}
},
cssCache: {},
css: function(name) {
if ($.ui.cssCache[name]) return $.ui.cssCache[name];
var tmp = $('<div class="ui-resizable-gen">').addClass(name).css(
{position:'absolute', top:'-5000px', left:'-5000px', display:'block'}
).appendTo('body');
//Opera and Safari set width and height to 0px instead of auto
//Safari returns rgba(0,0,0,0) when bgcolor is not set
$.ui.cssCache[name] = !!(
((/^[1-9]/).test(tmp.css('height')) || (/^[1-9]/).test(tmp.css('width')) ||
!(/none/).test(tmp.css('backgroundImage')) || !(/transparent|rgba(0, 0, 0, 0)/).test(tmp.css('backgroundColor')))
);
try { $('body').get(0).removeChild(tmp.get(0)); } catch(e){}
return $.ui.cssCache[name];
},
disableSelection: function(e) {
if (!e) return;
e.unselectable = "on";
e.onselectstart = function() { return false; };
if (e.style) e.style.MozUserSelect = "none";
},
enableSelection: function(e) {
if (!e) return;
e.unselectable = "off";
e.onselectstart = function() { return true; };
if (e.style) e.style.MozUserSelect = "";
}
});
