Question

这是jQuery脚本尝试删除html表的第一列

var order_table = $('.hor-scroll').eq(1);
//alert(order_table.html());
var order_table_copy = order_table;

order_table_copy.find(".order-tables th:first-child").remove();     
order_table_copy.find(".order-tables td:first-child").remove();

但上面的脚本也删除了qty-table的th，td

      </tr>
   </tbody>
</table>

但是我不能排除qty-table，我尝试了很多不同但不起作用。

Answer 1

尝试order_table_copy.find(".order-tables th:first-child:not(.qty-table)")

另请查看:first-of-type。还记得jQuery选择器返回一个数组。因此，如果所有其他方法都失败了，您可以始终使用数组的js filter函数。

更新：要避免使用.qty-table，请确保所选的td不是.qty-table

下的td

order_table_copy.find(".order-tables tr td:first-child:not(.qty-table td)").remove();

jQuery选择器排除子表
