JQuery UI 可排序占位符样式问题

Question

我一直在试图为 friend 解决这个问题。他们有一个 HTML5 本地音乐播放器，允许用户拖放播放列表中的项目。然而，占位符的颜色没有显示，其他元素如高度和行高。这是 JSFiddle，因此您可以看到我在说什么:http://jsfiddle.net/aYYUU/预先感谢您的帮助。

Answer 1

尝试以下操作。这是因为占位符是一个空行。只需在其中附加 td 即可。

<table id="songList">

</table>

CSS

table input[type=checkbox], table button {
    border: none;
    margin: 0;
    padding: 0;
    width: 13px;
    height: 13px;
    position: relative;
    top: 1px;
}

table {
    border-spacing: 0;
    width: 100%;
}

JS

$('#songList tbody').sortable({
    refreshPositions: true,
    opacity: 0.6,
    scroll: true,
    containment: 'parent',
    placeholder: 'ui-placeholder',
    tolerance: 'pointer',
    'start': function (event, ui) {
        ui.placeholder.html("<td colspan='6'></td>")
    }
}).disableSelection();
