jquery-ui sortable / draggable order:奇怪的行为

标签: html jquery-ui

我将liul拖到另一个时发现了一种奇怪的行为:

print screen

如您所见,“项目1”显示为ul的第一项,但是萤火虫检查员将其显示为第二项。这种情况发生在我.draggable li并在.sortable上发布时(并非总是!)。 在某些时刻,我需要检查li的顺序,显然返回的顺序是在firebug检查员上显示的顺序而不是页面中显示的顺序。

修改: jsFiddle

js:

$('ul.draggable li').draggable({ 
    connectToSortable: ".sortable", 
    helper: function(event) {
        return $('<span class="t3Helper" />')
                .text($(this).text());
      },
    revert: "invalid",
    cursorAt: { top: 0, left: 0 }
});

$('ul.sortable').sortable({ 
    placeholder: "sortable-placeholder",
    helper: "clone",

    connectWith: ".sortable",
    cursorAt: { top: 0, left: 0 },
    update: function() { 
        if($('.draggable').children().length == 0 && last) {
            $('.draggable').after('<button type="button" class="btn btn-primary btn-large pull-right" id="btnVerify">Verifica</button>');
            $('#btnVerify').on('click', checkClosure);
            $('.draggable').hide();
            last = false;
        }
    },
    receive: function (event, ui) { // add this handler
        if(!ui.sender.hasClass("sortable")) {
            $(this).data().sortable.currentItem.attr("id", ui.sender.attr('id'));
            $(ui.item).detach(); // remove original item
        }
    }
});

使用连接的可排序项而不是使用可排序和可拖动的值可能是值得的。

你可能会觉得它有点简单,看起来不那么错,使用这样的东西:

<强> Working Example

$('.sortable1').sortable({
    placeholder: "sortable-placeholder",
    connectWith: ".sortable",
    helper: 'clone',
    revert: "invalid",
    cursorAt: {
        top: 0,
        left: 0
    },
    update: function () {
        var last = true;
        if ($('.sortable1').children().length === 0 && last) {
            $('.sortable1').after('<button type="button" class="btn btn-primary btn-large pull-right" id="btnVerify">check</button>');
            $('#btnVerify').on('click', checkClosure);
            $('.sortable1').hide();
            last = false;
        }
    }
});

$('.sortable').sortable({
    placeholder: "sortable-placeholder",
    helper: "clone",

    connectWith: ".sortable",
    cursorAt: {
        top: 0,
        left: 0
    },

    receive: function (event, ui) { // add this handler
        if (!ui.sender.hasClass("sortable")) {
            $(this).data().sortable.currentItem.attr("id", ui.sender.attr('id'));
            $(ui.item).detach(); // remove original item
        }
    }
});
