L'ho capito !! In primo luogo, fare le file della griglia trascinabili (questa funzione dovrebbe essere chiamata in gridComplete gestore di eventi griglia):
function makeGridRowsDraggable() {
var $searchResultsGrid = $("#searchResultsGrid"),
$searchResultsRows = $("#searchResultsContainer .ui-row-ltr");
$searchResultsRows.css("cursor","move").draggable("destroy").draggable({
revert: "false",
appendTo: 'body',
cursor: "move",
cursorAt: {
top: 10,
left: -5
},
helper: function(event) {
//get a hold of the row id
var rowId = $(this).attr('id');
//use the row id you found to get the column text; by using the getCell method as below,
//the 'unformatter' on that column is called; so, if value was formatted using a
//formatter, this method will return the unformatted value
//(as long as you defined an unformatter/using a built-in formatter)
var theValue = $searchResultsGrid.jqGrid('getCell', rowId, 'desiredValue');
//set the data on this to the value to grab when you drop into input box
$(this).data('colValue', theValue);
return $("<div class='draggedValue ui-widget-header ui-corner-all'>" + theValue+ "</div>");
},
start: function(event, ui) {
//fade the grid
$(this).parent().fadeTo('fast', 0.5);
},
stop: function(event, ui) {
$(this).parent().fadeTo(0, 1);
}
});
}
Quindi, creare elementi droppable:
function createDroppableElements() {
$("#inputFieldOne, #inputFieldTwo").droppable({
tolerance: 'pointer',
hoverClass: 'active',
activate: function(event, ui) {
$(this).addClass("over");
},
deactivate: function(event, ui) {
$(this).removeClass("over");
},
drop: function(event, ui) {
var theValue = ui.draggable.data('colValue');
theValue = theValue .replace(/<br>/gi,'; ');
console.log("dropped value: " + theValue);
updateText($(this), theValue);
}
});
}
Creare un metodo di supporto per aggiungere testo a testo campo (che si aggiunge a ";"):
function updateText(txtTarget, theValue) {
var currentValue = txtTarget.val().trim();
if (currentValue.length > 0
&& currentValue.substr(currentValue.length-1) !== ";")
currentValue = currentValue + '; ';
currentValue += theValue;
txtTarget.val(currentValue);
}
