Question

我有一个包含数十万行的大型数据库，所以我想在不使用DataTables JQuery插件（或其他）显示我的结果的情况下进行服务器端处理。在我的代码示例下面的表格：

searchtable();
sortabletable();

function searchtable() {
  $("#searchtable").keyup(function() {
    var value = this.value.toLowerCase().trim();

    $("table tbody tr").each(function(index) {
      if (!index) return;
      $(this).find("td").each(function() {
        var id = $(this).text().toLowerCase().trim();
        var not_found = (id.indexOf(value) == -1);
        $(this).closest('tr').toggle(!not_found);
        return not_found;
      });
    });
  });
}

function sortabletable() {
  $('.sortable').each(function() {
    var $table = $(this); // This sortable table
    var $tbody = $table.find('tbody'); // Store table body
    var $controls = $table.find('th'); // Store table headers
    var rows = $tbody.find('tr').toArray(); // Store array containing rows

    $controls.on('click', function() { // When user clicks on a header
      var $header = $(this); // Get the header
      var order = $header.data('sort'); // Get value of data-sort attribute
      var column; // Declare variable called column

      // If selected item has ascending or descending class, reverse contents
      if ($header.is('.ascending') || $header.is('.descending')) {
        $header.toggleClass('ascending descending'); // Toggle to other class
        $tbody.append(rows.reverse()); // Reverse the array
      } else { // Otherwise perform a sort                            
        $header.addClass('ascending'); // Add class to header
        // Remove asc or desc from all other headers
        $header.siblings().removeClass('ascending descending');
        if (compare.hasOwnProperty(order)) { // If compare object has method
          column = $controls.index(this); // Search for columnâ€™s index no

          rows.sort(function(a, b) { // Call sort() on rows array
            a = $(a).find('td').eq(column).text(); // Get text of column in row a
            b = $(b).find('td').eq(column).text(); // Get text of column in row b
            return compare[order](a, b); // Call compare method
          });

          $tbody.append(rows);
        }
      }
    });
  });
  
  var compare = { // Declare compare object
    name: function(a, b) { // Add a method called name
      a = a.replace(/^the /i, ''); // Remove The from start of parameter
      b = b.replace(/^the /i, ''); // Remove The from start of parameter

      if (a < b) { // If value a is less than value b
        return -1; // Return -1
      } else { // Otherwise
        return a > b ? 1 : 0; // If a is greater than b return 1 OR
      } // if they are the same return 0
    },
    duration: function(a, b) { // Add a method called duration
      a = a.split(':'); // Split the time at the colon
      b = b.split(':'); // Split the time at the colon

      a = Number(a[0]) * 60 + Number(a[1]); // Convert the time to seconds
      b = Number(b[0]) * 60 + Number(b[1]); // Convert the time to seconds

      return a - b; // Return a minus b
    },
    date: function(a, b) { // Add a method called date
      a = new Date(a); // New Date object to hold the date
      b = new Date(b); // New Date object to hold the date

      return a - b; // Return a minus b
    },
    nope: function(a, b) {
      return a - b;
    }
  };
}

MySQL返回有限的行，我可以轻松地创建一个Ajax POST来检索更多tr个对象，但是如何在整个数据库内进行过滤和搜索，而不仅仅是通过对象在页面上显示？

Answer 1

我认为你应该使用angular.js并获取所有数据并存储在json对象中。然后使用分页来限制你要显示的数据。当你搜索时，你应该搜索那个json对象。

Answer 2

我相信你的问题的答案将改变一点SQL语句并添加字段“限制”。像

def stream_data(dataset_name, table_name, data): bigquery_client = bigquery.Client() dataset = bigquery_client.dataset(dataset_name) table = dataset.table(table_name) # Reload the table to get the schema. table.reload() rows = data errors = table.insert_data(rows) if not errors: print('Loaded 1 row into {}:{}'.format(dataset_name, table_name)) else: print('Errors:') print(errors)的位置：

“数字”返回的结果数
“digit1，digit2”，其中“digit1”是起始编号（例如第二页或第二个ajax请求），“digit2”与“digit”相同 - 总共返回的结果数。

如何在表中检索有限数量的行但在所有数据库集中搜索？
