DataTables过滤单元格内容而不是DB值

Question

使用DataTables 1.10.19

我有一个MySQL DB,结构如下;

+------+-----------------+----------+----------+
| name | email           | status   | complete |    
+------+-----------------+----------+----------+
| Joe  | me@example.com  | 1        |1         |
+------+-----------------+----------+----------+
| Jim  | you@example.com | 1        |0         |
+------+-----------------+----------+----------+
| Sara | him@example.com | 0        |0         |
+------+-----------------+----------+----------+

我正在使用此脚本从数据库中检索数据.

我的数据表过滤器工作正常搜索时0和1,但这种过滤器都 status和complete列.我想搜索词 active/inactive和complete/ incomplete,而不是 1和0.

我正在使用datatables columns.render选项根据行结果在这些列中呈现自定义输出.

我的DataTable代码是;

$('#example').dataTable({
    "ajaxSource": "results.php", // output below
    "columns": [{
        "data": "name"
    }, {
        "data": "email"
    }, {
        "data": "status",
        "render": function(data, type, row, meta) {
            // row[2] returns an int of 0 or 1 from the db. inactive/active
            if (row[2] == 0) {
                return `inactive`;
            }
            if (row[2] == 1) {
                return `active`;
            }
        }
    }, {
        "data": "complete",
        "render": function(data, type, row, meta) {
            // row[2] returns an int of 0 or 1 from the db. incomplete/complete
            if (row[3] == 0) {
                return `incomplete`;
            }
            if (row[3] == 1) {
                return `complete`;
            }
        }
    }, ]
});

该results.php文件返回以下内容;

"data": [
    [
      "Joe",
      "me@example.com  ",
      "1",
      "1",
    ],
    [
      "Jim",
      "you@example.com  ",
      "1",
      "0",
    ],
    [
      "Sara",
      "him@example.com  ",
      "0",
      "0",
    ],
]

我的前端HTML表看起来像这样;

+------+-----------------+----------+------------+
| name | email           | status   |complete    |
+------+-----------------+----------+------------+
| Joe  | me@example.com  | active   |complete    |
+------+-----------------+----------+------------+
| Jim  | you@example.com | active   |incomplete  | 
+------+-----------------+----------+------------+
| Sara | him@example.com | inactive |incomplete  |
+------+-----------------+----------+------------+

目前,过滤器似乎过滤了db int值而不是单元格文本.

如何搜索单词而不是0和1.

Answer 1

下面的似乎工作得很好。输入“Inactive”仅显示 Sara 结果。你在做什么不同的事情？

编辑：我已经更新了代码片段以匹配您的最新代码。看来您正在为您的数据传递一个数组数组，所以我很惊讶您的表甚至正在初始化，因为选项data在这种情况下无效（如果结果集中不存在，如何data选择该属性"name"？应该是数组索引）。将数据选项更新到数组索引后，该表将正确搜索渲染的表。搜索“不完整”会返回 Jim/Sara，而搜索“Inactive”则会返回 Sara。

$(document).ready(function() {
  var data = getDummyData();
  $('#example').dataTable({
    "data": data,
    "columns": [{
        "data": 0
      },
      {
        "data": 1
      },
      {
        "data": 2,
        "render": function(data, type, row, meta) {
          // row[2] returns an int of 0 or 1 from the db. inactive/active
          if (data == 0) {
            return `inactive`;
          }
          if (data == 1) {
            return `active`;
          }
        }
      },
      {
        "data": 3,
        "render": function(data, type, row, meta) {
          // row[2] returns an int of 0 or 1 from the db. incomplete/complete
          if (data == 0) {
            return `incomplete`;
          }
          if (data == 1) {
            return `complete`;
          }
        }
      },
    ]
  });
});

function getDummyData() {
  return [
    [
      "Joe",
      "me@example.com  ",
      "1",
      "1",
    ],
    [
      "Jim",
      "you@example.com  ",
      "1",
      "0",
    ],
    [
      "Sara",
      "him@example.com  ",
      "0",
      "0",
    ],
  ]
}
