javascript - 如何在过滤时排除类隐藏行和 noprint 行

Question

我有一个表格，其中包含一些隐藏且不可打印的单元格。我有一个脚本可以在此表中搜索并显示所需的单元格，但此脚本无法排除隐藏和 noprint <td> s。你能帮我解决这个问题吗？

var $rows_ku = $('#ku_list tr');
$('#search_ku').keyup(function() {
  var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase();

  $rows_ku.show().filter(function() {
    var text = $(this).text().replace(/\s+/g, ' ').toLowerCase();
    return !~text.indexOf(val);
  }).hide();
});

Answer 1

试试这个:

在这种情况下，始终显示标题(即:thead)内容。

    var $rows_ku = $('#ku_list tbody tr');
    $('#search_ku').keyup(function() {
       var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase();

       $rows_ku.show().filter(function() {
          var text = $(this).find('td:not(.hidden,.noprint)').text().replace(/\s+/g, ' ').toLowerCase();
          return !~text.indexOf(val);
   }).hide();});

选择器td:not(.hidden,.noprint)排除hidden和noprint类。
