数据表单列搜索

时间：2016-02-05 13:23:21

标签： javascript jquery datatable datatables

我有一个基本表格，我只想搜索一个列。

到目前为止，我的代码是here in this fiddle。

正如您在每列的底部所看到的，有一个搜索过滤器，但我只希望在office列上有一个搜索过滤器。

如果搜索过滤器位于顶部，而不是现在的底部也是好的。

基本上我希望我的表看起来与this one类似，但不是每列上的过滤器，我只想在一个上使用一个过滤器列。

感谢任何帮助。

我的代码如下。

// 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();
    }
  });
});

只需替换您的代码

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

带

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

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

如你所见，我将tfoot替换为thead，将搜索框设置在顶部。 我放置条件显示＆＃34; office＆＃34;

的搜索框

我知道这个问题已经得到解答，

     

然而，它可能对某些人有用......

替代最小化示例：

来自：

// 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();
    }
  });

致：

 //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()
 }
