这是一个 JSON 数组数据。我正在使用 ajax 填充此数据。但低于警告信息

DataTables warning: table id=scrip-data - Invalid JSON response

谁能指出我哪里做错了。下面是我的 ajax sn-p 加载数据表。

var data1 = JSON.parse('<%- gsdata %>') ; //ejs template to read value of data send from controller    
var table = $('#scrip-data').DataTable( {
    "searching": false,
    paging: false,
    info: false,
    "processing": true,
    //"serverSide": true,
        ajax: {
            url: "dashboard",
            //type: "GET",
            dataSrc: "",
        },
        data: data1,
        //dataType: 'json',
        columns: [
            {data: "SCRIP"},
            {data: "LTP"},
            {data: "CAMARILLA"},
            {data: "ALERT"},
            {data: "PROFIT"},
            {data: "updatedAt"},
        ],
        //columnDefs: [{ }],
    } );

    setInterval( function () {
            table.ajax.reload();
        }, 20000 );

【问题讨论】：

它错过了周围的花括号
引用的 JSON 确实无效。开头需要{，结尾需要}。如果你添加它们，它是有效的。或者，删除开头的"gsdata" : 以仅有一个数组。（{} 是一个具有gsdata 属性的对象。）

标签： javascript node.js json ajax ejs

【解决方案1】：

只需在 json 字符串周围添加大括号即可。
