jQuery不根据子元素属性进行选择

Question

I'm trying to modify this code, such that, it does not select rows that have the child <td colspan="12">

$('#my-table tbody>tr').hide();

I've tried this:

$('#my-table tbody>tr:not(tr>td[colspan="12"])').hide();

and several similar variations with small tweaks, but I can't get the syntax right. What am I doing wrong?

Answer 1

使用：has（）：

$('#my-table tbody>tr:not(:has(td[colspan=12]))').hide();

Answer 2

If you need more flexibility or a more complex condition than @roasted's answer, you can use .filter() :

$('#my-table tbody>tr').filter(function() {
  return $(this).children('td[colspan="12"]').length === 0;
}).hide();
