结合jQuery可拖动、可拖放和可排序

Question

我试图将jQuery可拖动、可拖放和可排序相结合；然而，我一直有问题。有人能帮帮我吗？

• A、 B、C、D、E瓷砖可在上部可放下和可分拣之间移动

此外，我正试图在必要时在任何位置停用和重新激活所有这些。

这是我的，但它很有缺陷，也不漂亮：

JS

var gameContainer = $(".game");

var myTray = $(".tray").sortable({
    containment: gameContainer,
    helper: "clone",
    revert: 100,
    tolerance: "pointer",
    update: function(ev, ui) {
        ui.item.addClass("ontray").css({
            "left": "0px",
            "position": "static",
            "top": "0px"
        });
    }
}).disableSelection();

var setTileDraggable = function(tileSelector) {
    tileSelector.draggable({
        connectToSortable: myTray,
        containment: gameContainer,
        helper: "original",
        revert: "invalid"
    }).disableSelection();
};

var myBoard = $(".board").droppable({
    accept: ".tile:not(.red)",
    drop: function(ev, ui) {
        if (ui.draggable.hasClass("ontray")) {
            // tile (not red) coming from tray, place it into .tiles child div
            var cloneTile = ui.draggable.clone().removeClass("ontray").show();
            myBoard.children(".tiles").append(cloneTile);
            var dropx = ui.offset.left - myBoard.offset().left;
            var dropy = ui.offset.top - myBoard.offset().top;
            cloneTile.css({
                "left": dropx + "px",
                "position": "absolute",
                "top": dropy + "px"
            });
            setTileDraggable(cloneTile);
            ui.helper.remove();
            ui.draggable.remove();
        }
    }
}).disableSelection();

var myCustomTile = $(".custom").droppable({
    accept: ".tile.red",
    drop: function(ev, ui) {
        if (ui.draggable.hasClass("ontray")) {
            // red tile coming from tray
            var cloneTile = ui.draggable.clone().removeClass("ontray").show();
            myCustomTile.append(cloneTile);
            setTileDraggable(cloneTile);
            setTileClick(cloneTile);
            ui.helper.remove();
            ui.draggable.remove();
        } else {
            // red tile staying, move back to original position
            ui.draggable.stop(true, false).animate({
                "left": "0px",
                "top": "0px"
            });
        }
    }
}).disableSelection();

// set up draggables
setTileDraggable(myBoard.children(".tiles").find(".tile"));
setTileDraggable(myCustomTile.find(".tile"));

好吧，我想起来了：http://codepen.io/anon/pen/jxDCt这实际上效果很好。

Answer 2

如果你把所有的盒子都分类，这将是一个容易得多的项目，因为它们有现成的方法可以轻松地相互连接。下面是您的示例的快速实现：

现场演示

$('.alpha').sortable({
  connectWith: '.gamma',
  receive: function (event, ui) {
    if ($(ui.item).hasClass('special')) {
      ui.sender.sortable('cancel');
    }
  }
});

$('.beta').sortable({
  connectWith: '.gamma',
  receive: function (event, ui) {
    if (!$(ui.item).hasClass('special')) {
      ui.sender.sortable('cancel');
    }
  }
});

$('.gamma').sortable({
  appendTo: document.body,
  items: '.tile',
  connectWith: '.alpha, .beta',
  receive: function (event, ui) {
    //console.log(event, ui.item);
    //ui.item.remove(); // remove original item
  }
});

你可以看到它主要是

• 设置排序表，并且
• 根据您的规格，创建接受或拒绝特定类型瓷砖的自定义接收事件
