數據表單列搜索

Question

我有一個基本表，我只想搜索一列。

我到目前為止所擁有的代碼就在這里 。

如您所見，每列底部都有一個搜索過濾器，但是我只希望office列上有一個搜索過濾器。

如果搜索過濾器位於頂部，而不是現在的底部，那也很好。

基本上，我想我的表，類似於這一個 ，然而相反的，每列過濾器的，我只希望在一列一個過濾器。

任何幫助表示贊賞。

我的代碼如下。

 // Setup - add a text input to each footer cell $('#example tfoot th').each(function() { var title = $(this).text(); $(this).html('<input type="text" placeholder="Search ' + title + '" />'); }); // DataTable var table = $('#example').DataTable(); // Apply the search table.columns().every(function() { var that = this; $('input', this.footer()).on('keyup change', function() { if (that.search() !== this.value) { that .search(this.value) .draw(); } }); });

Answer 1

只需替換您的代碼

$('#example tfoot th').each(function() {
  var title = $(this).text();
  $(this).html('<input type="text" placeholder="Search ' + title + '" />');
});

與

$('#example thead th').each(function() {

  var title = $(this).text();
  if(title == 'Office'){
  $(this).append('<br /><input type="text" placeholder="Search ' + title + '" />');
  }
});

如您所見，我將tfoot替換為thead，將搜索框置於頂部。 然后放置條件以顯示“辦公室”的搜索框

Answer 2

我知道這個問題已經回答了，

但是，它可能對某些人有用。

替代最小化示例：

來自：

// Setup - add a text input to each footer cell
$('#example tfoot th').each(function() {
  var title = $(this).text();
  $(this).html('<input type="text" placeholder="Search ' + title + '" />');
});

// DataTable
var table = $('#example').DataTable();

// Apply the search
table.columns().every(function() {
  var that = this;

  $('input', this.footer()).on('keyup change', function() {
    if (that.search() !== this.value) {
      that
        .search(this.value)
        .draw();
    }
  });

至 ：

 //Setup - add a text input to each footer cell
 $('#example tfoot th').each(function(i) {
  var title = $(this).text();
  var events = 'onchange="SearchCol(this,'+i+')"'
      events+= ' onkeyup="SearchCol(this,'+i+')"'
  $(this).html('<input type="text" '+events+' placeholder="Search '+title+'" />');
 });
 // Search Specific Column
 function SearchCol(input,col_index){
  var query = $(input).val()
  $("#example").DataTable().column(col_index).search(query).draw()
 }
