Question

我有一个带有两列的数据表，＆＃34; Name＆＃34;和＆＃34;年龄＆＃34;在用Ajax填充数据表后，我创建了一个按钮（每行一个）。这很好用。但是在用户点击按钮后，该行的两个字段（名称和年龄）应该被发送到php，然后发出这样的警告＆＃34;您好，我的名字是[姓名]而我是[年龄]岁＆＃34;。（我需要这里的PHP）。我写了一个可以调用php的代码，但我不知道如何将每行的参数发送到php。我怎么能这样做？

我的js：

<script type="text/javascript">
$(document).ready(function() {

var oTable = $('#jsontable').dataTable(
    $('td:eq(2)', nRow).html("<input type='button' id='button' onclick='test();' value='Click to Release'></input>");
    );  ///This is created after ajax

    $('#load').on('click',function(){
        var user = $(this).attr('id');
        if(user != '') 
        { 
        $.ajax({
            url: 'response.php?method=fetchdata',
            type: 'POST',
            data: {id1: $('#id1').val()},
            dataType: 'json',
            success: function(s){
            console.log(s);
                    oTable.fnClearTable();
                        for(var i = 0; i < s.length; i++) {
                         oTable.fnAddData([
                                    s[i][0],
                                    s[i][1]
                                           ]);                                      
                                        } // End For

            },
            error: function(e){
               console.log(e.responseText); 
            }
            });
        }
    });
});

function test() {
  $.ajax( { type : 'POST',
            data : { },
            url  : 'process_form.php',              // <=== CALL THE PHP FUNCTION HERE.
            success: function ( data ) {
              alert( data );               // <=== VALUE RETURNED FROM FUNCTION.
            },
            error: function ( xhr ) {
              alert( "error" );
            }
          });
}

</script>

process_form.php

<?php

    function bb()
    {
    echo "hellooooo"; //How to pass the name and the age field to php here from each row of the datatable?
    }

    bb();
?>

执行您想要的代码。我使用table.row而不是table.cell，这样更容易。

＆＃13;

$(document).ready(function() {
    
    var table = $('#table_id').DataTable();

    $('#table_id').on( 'click', 'button', function () {
    var index = table.row( this ).index();
    var data_row = table.row( $(this).parents('tr') ).data();
    alert('Name: ' + data_row[0] + "\n" + 'Age: ' + data_row[1]);
} );
});

＆＃13;

/*
 * Table
 */
table.dataTable {
    margin: 0 auto;
    clear: both;
    width: 100%;
}

table.dataTable thead th {
    padding: 3px 18px 3px 10px;
    border-bottom: 1px solid black;
    font-weight: bold;
    cursor: pointer;
    *cursor: hand;
}

table.dataTable tfoot th {
    padding: 3px 18px 3px 10px;
    border-top: 1px solid black;
    font-weight: bold;
}

table.dataTable td {
    padding: 3px 10px;
}

table.dataTable td.center,
table.dataTable td.dataTables_empty {
    text-align: center;
}

table.dataTable tr.odd { background-color: #E2E4FF; }
table.dataTable tr.even { background-color: white; }

table.dataTable tr.odd td.sorting_1 { background-color: #D3D6FF; }
table.dataTable tr.odd td.sorting_2 { background-color: #DADCFF; }
table.dataTable tr.odd td.sorting_3 { background-color: #E0E2FF; }
table.dataTable tr.even td.sorting_1 { background-color: #EAEBFF; }
table.dataTable tr.even td.sorting_2 { background-color: #F2F3FF; }
table.dataTable tr.even td.sorting_3 { background-color: #F9F9FF; }

要通过ajax发送数据，请将警报替换为ajax代码。

JS：

$(document).ready(function() {

    //your code for construct the table 
    var table = $('#table_id').DataTable();//change this to be equal to the id of your table

    $('#table_id').on( 'click', 'button', function () { //change this to be equal to the id of your table
    var index = table.row( this ).index();
    var data_row = table.row( $(this).parents('tr') ).data();
    //alert('Name: ' + data_row[0] + "\n" + 'Age: ' + data_row[1]);
    $.ajax( { 
            type : 'POST',
            data : {'data0': data_row[0], 'data1': data_row[1] },
            url  : 'process_form.php',            
            success: function ( data ) {
              alert( data );              
            },
            error: function ( xhr ) {
              alert( "error" );
            }
          });
} );
});

PHP：

$name = $_POST['data0'];//to get the name value
$age = $_POST['data1'];//to get the age value
//your code

$(document).ready(function(){
	fill_data();
	$(document).on('click','button', function(){
		alert("Hello, my name is "+$(this).closest("tr").find(".name").text()+" and i'm "+$(this).closest("tr").find(".age").text()+" years old.");
	});
});

function fill_data(){
	var content = "";
	for(var i = 0; i < 10; i++){
		content = content+"<tr><td class='name'>"+"Name_"+i+"</td><td class='age'>"+i+"</td><td><button>Call</button></td></tr>";
	}
	$('#data_table_body').html(content);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
      <th>Action</th>
    </tr>

  <tbody id="data_table_body">
