我需要你的帮助。
由于 IE7 选择忽略 TD: whitespace: nowrap 的方式,我被迫在我的 TD 前面放置和使用跨度,所以这就是德尔马。当我单击 td 之间没有跨度的表行时,编码能够提取数据并突出显示该行。
但是,当我在我的 td 之间引入一个跨度并单击以选择具有跨度的表行中的单个单元格时,我收到以下错误:“cells.0 为空或不是对象。” 我知道如果我在表格单元格的一侧单击一点它就可以工作,但是我还需要能够单击<TD>
和<SPAN>
区域并让代码工作。
既然我正在制作一个表格,所有<span></span>
的都在所有之间,<TD>
那么现有的编码如何重新格式化以适应从<td>data</td>
to的差异<td><span>data</span></td>
?
请不要使用 jQuery。
