Jquery Ui:可选择 - 可以 select 一次单击两个列表项?

Jquery Ui: Selectable - possible to select two list items with one click?

我正在列表中使用 Jquery Ui: selectable,我正在尝试弄清楚如何 select 一次单击两个列表元素。我想要它,以便当列表项为 clicked/selected 时,列表中的下一项也得到 selected.

ASPX 页面:

<button id="joinButton" type="button" class="collapsible inactiveSequenceTitle">
    <span style="margin-left: 0.35em;" class="icon expand-icon glyphicon glyphicon-plus">
    &nbsp
    </span>Join Sections
</button>
<div id="joinBox" class="panel-collapse collapse">
    <ul id="sortableJoin-1" style="width: 98%; margin: auto;"></ul>

    <div id="saveJoin">
        <button type="button" class="btn btn-primary" id="join">
            <span class="fa fa-save">
            &nbsp
            </span>Join 
        </button>
    </div>
</div>

Jquery/Jvascript:

$("#sortableJoin-1").selectable({
    selected: function(event, ui) {
        var selected = $("li[class$='ui-selected']").length;
    }
    stop: function (e) {
        var last = $("li[class$='ui-selected']:last").index();
        $("li:eq(" + (last + 1) + ")").addClass("ui-selected");
    },
});

$('#sortableJoin-1').click(function() {
    $(this).addClass('no-hover');
})

您可以使用在 select 操作结束时触发的 stop 事件 select 编辑项目的下一个项目。在 stop 中,获取带有 class ui-selected 的最后一个元素的索引,并将此 class 添加到列表中的下一个元素。

$("#sortableJoin-1").selectable({
  selected: function(event, ui) {
    var selected = $("li[class$='ui-selected']").length;
  },
  stop: function(e) {
   var last = $("li[class$='ui-selected']:last").index();
   $("li:eq(" + (last + 1) + ")").addClass("ui-selected");
  }
});
 .ui-selected {
    background: red;
    color: white;
    font-weight: bold;
}
