Question

我想使用REST API和jQuery插件DataTable从https://swapi.co/api/planets/?format=json数据中获取所有json，但是我的问题是，它首先加载了数据，但是当我开始输入Datatable提供的搜索字段时。，它显示“ 表中没有数据”。

我一直在搜索类似的问题，但仍然找不到解决方案。我尝试过的是

我的HTML文件：

rest.html


<table id="tableSwapi" class="table table-striped">
         <thead>
            <tr>
                <th>Name</th>
                <th>Rotation Period</th>
                <th>Orbital Period</th>
                 <th>Diameter</th>
                 <th>Climate</th>
                 <th>Gravity</th>
                 <th>Terrain</th>
                 <th>Water Surface</th>
                 <th>Population</th>
            </tr>
         </thead>
         <tbody id="list-list">

         </tbody>
</table>

我的脚本文件：

script.js

$(document).ready(function () {
 $("#tableSwapi").dataTable();

$.ajax({
        url: 'https://swapi.co/api/planets/',
        type: 'get',
        dataType: 'json',
        success: function (result) {
            let daftar = result.results;
            var html = '';
            $.each(daftar, function (i, data) {             
                html += `<tr>
                            <td> ` + data.name + `</td>
                            <td>` + data.rotation_period + `</td>
                            <td>` + data.orbital_period + `</td>
                            <td>` + data.diameter + `</td>
                            <td> ` + data.climate + ` </td>
                            <td> ` + data.gravity + ` </td>
                            <td>` + data.terrain + `</td>
                            <td> ` + data.surface_water + `</td>
                            <td> ` + data.population + ` <br></td>
                        </tr>`;

                //This is selector of my <tbody> in my table
                $("#list-list").html(html);
            });
        }
    });
})

任何帮助都将受到赞赏。谢谢。

如果您可以使用服务器端脚本，请尝试使用类似的代码

PHP代码ajax.php

$url = "https://swapi.co/api/planets/?page=".($_GET['start']/$_GET['length']+1); 
if (isset($_GET['search']) && !empty($_GET['search'])) {
    $url .= "&search=".$_GET['search']['value'];
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_URL, $url);
$result = json_decode(curl_exec($ch),true);
$array = array
        (
            "draw" => $_GET['draw'],
            "recordsTotal" => $result['count'],
            "recordsFiltered" => $result['count'],
            "data" => $result['results'],
        );
echo json_encode($array);

jQuery数据表代码

$('#tableSwapi').DataTable({
    "processing": true,
    "serverSide": true,
    "sPaginationType": "full_numbers",
    "order": [],
    "ajax": {
        "url": "ajax.php",
        "type": 'get',
        "dataType": 'json'
    },
    "columns": [
        { "data": "name" },
        { "data": "rotation_period" },
        { "data": "orbital_period" },
        { "data": "diameter" },
        { "data": "climate" },
        { "data": "gravity" },
        { "data": "terrain" },
        { "data": "surface_water" },
        { "data": "population" },
    ]
});

Datatable插件可能有问题。请检入检查元素。

如何从rest api json使用jQuery Datatable插件？

rest.html

script.js
