Question

我有一个可选择的列表，我也想要排序。我还想禁用列表中的套索功能，因为可选列表可以通过点击而不是使用套索功能选择多个项目。当我尝试在我的代码中添加$（'＃selectable'）。sortable（）时，列表不再可选，但它是可排序的。

这是我的jsfiddle的链接：

这是我目前的javascript代码：

var $currentlySelected = null;
var selected = [];

$('#selectable').sortable();
$('#selectable').selectable({
start: function(event, ui) {
    $currentlySelected = $('#selectable .ui-selected');
},
stop: function(event, ui) {
    for (var i = 0; i < selected.length; i++) {
        if ($.inArray(selected[i], $currentlySelected) >= 0) {
          $(selected[i]).removeClass('ui-selected');
        }
    }
    selected = [];
},
selecting: function(event, ui) {
    $currentlySelected.addClass('ui-selected'); // re-apply ui-selected class to currently selected items
},
selected: function(event, ui) {
    selected.push(ui.selected); 
}
});

您可能无法同时执行这两项操作，因为sortable和selectable都在同一个click事件中，而只是让持有者进行排序。

$('#selectable').sortable({ handle: ".holder" })//Make sortable on the handle
  .selectable({
    start: function(event, ui) {
        $currentlySelected = $('#selectable .ui-selected');
    }
    ,cancel: ".holder" //Cancel selection for holder
    ,
    stop: function(event, ui) {
        for (var i = 0; i < selected.length; i++) {
            if ($.inArray(selected[i], $currentlySelected) >= 0) {
              $(selected[i]).removeClass('ui-selected');
            }
        }
        selected = [];
    },
    selecting: function(event, ui) {
        $currentlySelected.addClass('ui-selected'); // re-apply ui-selected class to currently selected items
    },
    selected: function(event, ui) {
        selected.push(ui.selected); 
    }
}).find( "li" )
        .addClass( "ui-corner-all" )
         .prepend( 
             $('<div/>',
                 {'class':'holder'} )
            .append(
                 $('<span/>',
                     {'class':'ui-icon ui-icon-transfer-e-w'})
                  )
             );//Just prepend handle to li's or just addthem in your html itself and remove this section.

这是我的解决方法，使列表可选择和排序，并允许套索实现。这是fiddle。

<html>
<meta charset="utf-8" />
<title>jQuery UI Sortable with Selectable</title>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
$(function() {
//

$('body').selectable({
    filter: 'li'
    //filter: '#album2 > li'
});

/*
Since the sortable seems unable to move more than one object at a 
time, we'll do this:

The LIs should act only as wrappers for DIVs.

When sorting a LI, move all the DIVs that are children of selected 
LIs to inside the sorting LI (this will make them move together);
but before doing that, save inside the DIVs a reference to their
respective original parents, so we can restore them later.

When the user drop the sorting, restore the DIVs to their original
parent LIs and place those LIs right after the just-dropped LI.

Voilá!

Tip: doesn't work so great if you try to stick the LIs inside the LI
*/

$('.connectedSortable').sortable({
    connectWith: ".connectedSortable",
    delay: 100,
    start: function(e, ui) {
        var topleft = 0;

        // if the current sorting LI is not selected, select
        $(ui.item).addClass('ui-selected');

        $('.ui-selected div').each(function() {

            // save reference to original parent
            var originalParent = $(this).parent()[0];
            $(this).data('origin', originalParent);

            // position each DIV in cascade
            $(this).css('position', 'absolute');
            $(this).css('top', topleft);
            $(this).css('left', topleft);
            topleft += 20;

        }).appendTo(ui.item); // glue them all inside current sorting LI

    },
    stop: function(e, ui) {
        $(ui.item).children().each(function() {

            // restore all the DIVs in the sorting LI to their original parents
            var originalParent = $(this).data('origin');
            $(this).appendTo(originalParent);

            // remove the cascade positioning
            $(this).css('position', '');
            $(this).css('top', '');
            $(this).css('left', '');
        });

        // put the selected LIs after the just-dropped sorting LI
        $('#album .ui-selected').insertAfter(ui.item);

        // put the selected LIs after the just-dropped sorting LI
        $('#album2 .ui-selected').insertAfter(ui.item);
    }
});
