Question

我正在创建一个房间预订系统。所以我想只选择那些不可选择的td =＆＃34; off＆＃34;。请帮我这样做。

这是我的html代码，这是我用来选择它们的脚本。

<script>
$(function() {
    $( "table" ).selectable(
    {
        filter: 'tbody td unselectable:off '
    }
    );
});
</script>

但没有任何事情发生。请帮我解决这个问题。

            <tr>
                <td unselectable="on" resource="B" style="width: 79px; border-right: 1px solid #000000;
                    border-left: 1px solid #000000; border-bottom: 1px solid #000000; background-color: #ECE9D8;

看起来你刚刚得到过滤器的语法有点不对劲。您需要使用"attribute equals" selector：

$( "table" ).selectable({
    filter: 'tbody td[unselectable="off"]'
});

目前，您正在寻找unselectable类型的任何元素，它是td元素的后代，并使用名为:off的伪选择器，两者都不存在。

我想只选择那些不可选择=“关闭”的td
