我想只選那些td where unselectable =「off」

Question

我正在創建一個房間預訂系統。所以我想讓可選擇的那些td在哪裏取消選擇=「關閉」。請幫我做這個。

這是我的html代碼，這裏是我用來選擇它們的腳本。

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

但是什麼都沒有發生。 請幫我解決這個問題。

  <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; 
        font-family: Tahoma; font-size: 8pt; color: #000000; cursor: default;"> 
        <div unselectable="on" style="margin-left: 4px; height: 19px; line-height: 19px; 
         overflow: hidden;">

它看起來像你剛纔收到你的過濾器有點不對的語法。您需要使用一個"attribute equals" selector：

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

目前你正在尋找unselectable類型的任何元素是td元素的後裔，並使用僞選擇稱爲:off，這兩者都不存在。
