jQuery表列搜索过滤器 [英] jQuery table column search filter

问题描述

我正在尝试使用jquery在html表的特定列中搜索数据.我搜索了不同的答案，但找不到适合我的答案.

I'm trying to search for data in a specific column of an html table using jquery. I've searched for different answers but I can't find one that suits me.

表只是一个简单的表:

<table id="tabla">
  <tr>
    <th>TimeStamp</th>
    <th>IP</th>
    <th>Nombres</th>
    <th>Descripción</th>
  </tr>
</table>

我找到了一段代码，可以让您在整个表格中搜索数据:

I found a piece of code that allows you to search for data in the whole table:

var $rows = $('#tabla_servicios tr');
            var $col_ip = $('#ip');

            $('#buscar1').keyup(function() {

                var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase();

                $rows.show().filter(function() {
                    var text = $(this).text().replace(/\s+/g, ' ').toLowerCase();
                    return !~text.indexOf(val);
                }).hide();


            });

但是我想按列搜索.

这是我的第二种方法:

$('#buscar').click(function() {

                var table = document.getElementById("tabla_servicios");
                var sel_opt = document.getElementById("options");
                var busqueda =  $("#busqueda").prop("value");
                var column_sel = 0;


               if (sel_opt.value == "timestamp"){

                    //alert("opcion timestamp");
                    column_sel = 0;

               }else if (sel_opt.value == "ip"){

                    //alert("opcion ip");
                    column_sel = 1;                 

               }else if (sel_opt.value == "nombres"){

                    //alert("opcion nombres");
                    column_sel = 2;

               }else if (sel_opt.value == "descripcion"){

                    //alert("opcion descripcion");
                    column_sel = 3;

               }

               var column_length = $('#tabla_servicios tr th').length;
               //alert("column_length = "+column_length);
               var row_length = $('#tabla_servicios tr').length;



                for(row=1; row<row_length; row++){

                     var data=$('#tbody_tabla tr:eq('+row+') td:eq('+column_sel+')').text();
                     //alert("busqueda: "+busqueda+" data: "+data);

                     if(busqueda == data){

                        $('#tbody_tabla tr:eq('+row+')').remove();
                        data.parent().css("font-size: 200%");
                     }

                   }


                });

但是它无法正常工作，css代码不起作用，并且仅当我在if内添加警报时，才能删除该行.

But it doesn't work correctly, the css code doesn't work and for removing the row it works only when I add an alert inside the if.

推荐答案

您可以尝试以下操作:

HTML:

<table id="tabla">
    <tbody id="tbody_tabla">
        <tr>
        ----
        </tr>
    </tbody>
</table>

jQuery:

for(col=0;col<=column_length; col++){
    for(row=0; row<=row_length; row++){
        var data=$('#tbody_tabla tr:eq('+row+') td:eq('+col+')').text();
    }
}

您还可以动态找到列数和行数
例如:column_length = $("#tbody_tabla tr:first td").length;

Also you can find the number of columns and number of rows dynamically
Ex: column_length = $("#tbody_tabla tr:first td").length;
