Question

我可以在数据表中显示我的URL图像吗？我在数组中返回数据，如我在代码中显示的那样，并返回带有...的URL图像。

在我知道DataTables之前我使用的是默认表格，我将表格放在<img src="">中，那我该如何在这里使用呢？

<?php	
class basket_report{
function show_basket_report(){
	$connect_mysql= @mysql_connect($server,$username,$passwor) or die ("Connection Failed!");
	$mysql_db=mysql_select_db("GP15",$connect_mysql) or die ("Could not Connect to Database");
	$query = "SELECT * FROM reportBasket where notifyEmployee='1'";
	$result=mysql_query($query) or die("Query Failed : ".mysql_error());
	$objects= array();
    while($rows=mysql_fetch_array($result))
    {
                    $objects[]= $rows;
    }
	$data_set = "[";
    $count_rows = count($objects);
    $count = 1;
    foreach($objects as $object){
       $data_set .= "['". $object['reportID'] ."', '". $object['email'] ."', '". $object['date'] ."', '". $object['time'] ."', '". $object['BasketID'] ."', '". $object['notifyEmployee'] ."','". $object['replyedPhoto'] ."']";
        if($count != $count_rows){
            $data_set .= ",";
            $count++;
        }
    }
    $data_set .= "]";
		return $data_set;
	}
?>

您可以使用columns.render选项定义回调函数，以根据其数据呈现单元格内容。

$('#example').DataTable({
    "ajax": {
        url: "/test/0",
    },
    "columns": [
        { "data": 0 },
        { 
          "data": 1,
          "orderable": false,
          "sortable": false,
          "render": function (data, type, row, meta){
             // If data will be displayed
             if(type === "display"){
                return '<img src="' + data + '">';

             // Otherwise, if search/filtering is performed
             } else {
                return data;  
             }
          }
        }
    ]
});

请注意，如果您使用columns来定义列，那么您必须在数组中为表格中的每一列添加一个条目（如果您没有这些列，则可以是null ; t指定任何选项）。或者，您可以使用columnDefs定位特定列。

有关代码和演示，请参阅下面的示例。请注意，我仅仅为了演示Ajax请求而使用jQuery Mockjax插件，生产代码不需要它。

$(document).ready(function () {
   // AJAX emulation for demonstration only
   $.mockjax({
      url: '/test/0',
      responseTime: 200,
      responseText: {
         "data": [
            [ "100x150", "http://placehold.it/100x150" ],
            [ "200x150", "http://placehold.it/200x150" ],
            [ "300x150", "http://placehold.it/300x150" ]
         ]
      }
   });

   $('#example').DataTable({
       "ajax": {
           url: "/test/0",
       },
       "columns": [
           { "data": 0 },
           { 
             "data": 1,
             "orderable": false,
             "sortable": false,
             "render": function (data, type, row, meta){
                if(type === "display"){
                   return '<img src="' + data + '">';
                } else {
                   return data;  
                }
             }
           }
       ]
   });
});
