使用下拉列表过滤数据表列

时间：2017-09-27 09:54:32

标签： javascript jquery html datatables

根据下拉列值，我遇到数据表过滤记录问题。

我们假设Garrett Winters是与Tokyo，San Francisco等两个或更多办公室相关联的用户。如果我搜索Tokyo办公室，则Garrett Winters应该在该列表中，如果我搜索San Francisco办公室，则应再次Garrett Winters列入该列表。

目前在下拉列表中生成了Tokyo,San Francisco的新选项，仅在搜索Garrett Winters名称时不需要。

任何人都可以帮忙吗？

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

      column.data().unique().sort().each(function(d, j) {
        select.append('<option value="' + d + '">' + d + '</option>');
      });
    }

2 个答案:

答案 0 :(得分：2)

生成<option>时，如果它包含多个城市，则必须检查该值并删除重复的条目：

var values = [];
column.data().each(function(d, j) {
  d.split(",").forEach(function(data) {
    if (values.indexOf(data) === -1) {
      values.push(data);
    }
  });
});

第二个必要步骤是更改构建正则表达式以进行过滤的方式。目前，您只需要查找完整的行（^...$）而不是单词。这可以通过单词边界（\b）完成：

.on('change', function() {
  column.search(this.value ? '\\b' + this.value + '\\b' : "", true, false).draw();
})


$(document).ready(function() {
  $('#tableTrigger').DataTable({
    "lengthMenu": [
      [10, 25, 50, 100, -1],
      [10, 25, 50, 100, "All"]
    ],
    "scrollY": "200px",
    "dom": 'rtipS',
    "deferRender": true,
    "initComplete": function() {
      var column = this.api().column(2);

      var values = [];
      column.data().each(function(d, j) {
        d.split(",").forEach(function(data) {
          data = data.trim();
          
          if (values.indexOf(data) === -1) {
            values.push(data);
          }
        });
      });

      $('<select class="filter"><option value=""></option></select>')
        .append(values.sort().map(function(o) {
          return '<option value="' + o + '">' + o + '</option>';
        }))
        .on('change', function() {
          column.search(this.value ? '\\b' + this.value + '\\b' : "", true, false).draw();
        })
        .appendTo('#selectTriggerFilter');
    }
  });
});

答案 1 :(得分：2)

您必须拆分办公室字符串并构建您自己的唯一列表：

abs(B(2,jj)-A(2,ii)) <= 1

并将搜索更改回默认值，您不再需要正则表达式匹配

var offices = []; 
column.data().toArray().forEach(function(s) {
  s = s.split(',');
  s.forEach(function(d) {
    if (!~offices.indexOf(d)) {
      offices.push(d);
      select.append('<option value="' + d + '">' + d + '</option>');                                  
    }
  })
})
