具体方法可参照以下教程

https://www.w3school.com.cn/jquery/ajax_getjson.asp

下面写了一个示例代码

<!DOCTYPE html>
<html lang="zh">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>ajax_test</title>
        <link rel="stylesheet" href="css/bootstrap.css">
        <script src="js/jquery.min.js"></script>
        <script src="js/bootstrap.js"></script>
    </head>
    <body>
        <table class="table table-striped" id="tab">
            <tr>
                <th>货物编号</th>
                <th>货物id号</th>
                <th>货物名称</th>
                <th>数量（个）</th>
            </tr>
            <tr>
                <td>1</td>
                <td>12345</td>
                <td>洗面奶</td>
                <td>5</td>
            </tr>
        </table>
        <button id="btn">获得 JSON 数据</button>
    </body>
    
    <script type="text/javascript">
        $(document).ready(function() {
            $("#btn").click(function() {
                $.getJSON("./source.txt", function(result) {
                    console.log(result);
                    var context = "<tr><td>"+result.no+"</td><td>"+result.id+
                    "</td><td>"+result.name+"</td><td>"+result.num+"</td></tr>";
                    $("#tab").append(context);
                });
            });
        });
    </script>
</html>
