这对我有用。
在这里小提琴:
var selectedObjs;
var draggableOptions = {
start: function(event, ui) {
//get all selected...
if (ui.helper.hasClass('selected')) selectedObjs = $('div.selected');
else {
selectedObjs = $(ui.helper);
$('div.selected').removeClass('selected')
}
},
drag: function(event, ui) {
var currentLoc = $(this).position();
var prevLoc = $(this).data('prevLoc');
if (!prevLoc) {
prevLoc = ui.originalPosition;
}
var offsetLeft = currentLoc.left-prevLoc.left;
var offsetTop = currentLoc.top-prevLoc.top;
moveSelected(offsetLeft, offsetTop);
selectedObjs.each(function () {
$(this).removeData('prevLoc');
});
$(this).data('prevLoc', currentLoc);
}
};
$('.drag').draggable(draggableOptions).click(function() {$(this).toggleClass('selected')});
function moveSelected(ol, ot){
console.log("moving to: " + ol + ":" + ot);
selectedObjs.each(function(){
$this =$(this);
var p = $this.position();
var l = p.left;
var t = p.top;
console.log({id: $this.attr('id'), l: l, t: t});
$this.css('left', l+ol);
$this.css('top', t+ot);
})
}
感谢 ChrisThompson 和 green 提供了几乎完美的解决方案。
