在表格上選擇搜索按鈕后，如何將焦點移動到搜索結果？

CSS
錢艷冰2年前8瀏覽0評論

我在一個頁面上工作，我有一個搜索結果按鈕表。

一旦用戶選擇了& quot搜索結果& quot按鈕。我想把焦點放在& quot顯示X個條目& quot文本或下拉菜單，以便用戶知道頁面已更新了結果。

請指教。提前感謝。

這是我的代碼-

$(document).ready(function() {
  var table = $('#example').DataTable({
    
    responsive: true,
    searching: true,
    
    columnDefs: [
            {
                target: 6,
                visible: false,
                searchable: true,
            }
      ],
    
    dom: 'Bifrtip',
        buttons: [
            {
                extend: 'excelHtml5',
                exportOptions: {
                    columns: ':visible'
                }
            },
            {
                extend: 'pdfHtml5',
                orientation: 'landscape',
                exportOptions: {
                    columns: ':visible'
                     }
              },           
            {
                extend: 'print',
                exportOptions: {
                    columns: ':visible'
                }
               },
        //  'colvis'
        ],
  });

  buildSelect(table);
 
  table.on('draw search', function() {
    buildSelect(table);
  });
         
$('#myInput').on( 'click', function () {
  table.draw(); 
} );
          
  $('#test').on('click', function() {
    table.search('').columns().search('').draw();
  });
});

function buildSelect(table) {
  var counter = 0;
  table.columns([0, 1, 2]).every(function() {
    var column = table.column(this, {
      search: 'applied'
    });
    counter++;
    var select = $('<select><option value="">select me</option></select>')
      .appendTo($('#dropdown' + counter).empty())
      .on('change', function() {
        var val = $.fn.dataTable.util.escapeRegex(
          $(this).val()
        );

        column
          .search(val ? '^' + val + '$' : '', true, false);
          //.draw();
      });

    if ( column.index() === 0 ) {
      var filteredNames = column.data().unique().toArray();
      ['Garrett', 'Test1', 'Ashton'].forEach((d) => {
        if (filteredNames.includes(d)) {
          select.append('<option value="' + d + '">' + d + '</option>');
        }
      });
    } else {
      column.data().unique().sort().each(function(d, j) {
        select.append('<option value="' + d + '">' + d + '</option>');
      });
    }

    // The rebuild will clear the exisiting select, so it needs to be repopulated
    var currSearch = column.search();
    if (currSearch) {
      // ** MY CHANGE **
      // Use RegEx to find the selected value from the unique values of the column.
      // This will use the Regular Expression returned from column.search to find the first matching item in column.data().unique
      select.val(column.data().unique().toArray().find((e) => e.match(new RegExp(currSearch))));
    }
  });
}

你可以閃現(xiàn)你的搜索結果文本，并設置輸入到任何你想要的輸入元素，在我看來，把焦點放在文本上沒有多大意義。
