Question

好的，基本上，我有一个恰好是<tr>元素的元素。

但如果我找到行数大于1的<td>元素，则在任何<tr>元素中，我需要排除这些<tr>元素，从$开始（“td”）。parent（）其中rowspan＆gt; 1，我需要排除所有其他<tr>元素，直到each()

中的rowspan数量

这样的事情：

$("td").each(function{
if ($(this).attr('rowspan') > 1)
    var curRowspan = $(this).attr('rowspan');
    // So now rowspan can equal 2, 3, 4, 5, and higher.
    // Now I need to exclude the NEXT <tr> elements based on the quantity of rowspans.
    // So if the rowspan = 2, than I need to exclude $(this).parent() and $(this).parent().next() which seems easy enough, but I need this to work on more than 2 rowspans also.  Needs to exclude the current <tr> element and all <tr> elements after, until it reaches the rowspan quantity indicated by curRowspan.
    // HOW TO DO THIS and return false out of the each() for each of these `<td>` elements within that quantity of `<tr>` elements indicated by the rowspan of a `<td>` element???
});

您可以添加一个类来表示您忽略该行。我觉得有一种更好的方法来优化这个选择器。 Slice看起来很有希望。

$("td").each(function() {
    if ($(this).attr('rowspan') > 1) {        
        var curRowspan = $(this).attr('rowspan');
        $(this).parent().nextAll().slice(0, curRowspan).addClass('markRow');
    }
});

jQuery - 抓住所有next（）达到一定数量
