如何在DataTables中重新加载/刷新JavaScript数组 [英] How do I reload/refresh javascript array in DataTables

问题描述

我正在使用DataTables显示来自搜索功能的数据.我确定这是否是用于将数据传递到DataTables的预期方法.我正在用空白的javascript数组初始化DataTable.然后，我想用其他函数填充数据表.

I'm using DataTables to display data from a search function. I'm sure if this was intended method for passing data into DataTables. I'm initializing the DataTable with a blank javascript array. Then I want to populate Datatables in a different function.

我已经尝试过$().DataTable().ajax.reload()和$().DataTable().fnAddData(dataSet)，但都没有用.

I've tried $().DataTable().ajax.reload() and $().DataTable().fnAddData(dataSet) but both didn't work.

<table id="test" class="table table-striped table-bordered table-hover dt-responsive">
</table>

<a href="#" onclick="LoadData();">Test</a>


$(document).ready(function ()
    {

        $('#test').DataTable({
            data: dataSet,
            columns: [
                { title: "Name" },
                { title: "Position" },
                { title: "Office" },
                { title: "Extn." },
                { title: "Start date" },
                { title: "Salary" }
            ]
        });
    });

    var dataSet = [];

    function LoadData()
    {
        dataSet = [
                ["Tiger Nixon", "System Architect", "Edinburgh", "5421", "2011/04/25", "$320,800"],
                ["Garrett Winters", "Accountant", "Tokyo", "8422", "2011/07/25", "$170,750"],
                ["Ashton Cox", "Junior Technical Author", "San Francisco", "1562", "2009/01/12", "$86,000"],
        ];

        var tbl = $('#test').DataTable();

        tbl.fnClearTable();
        tbl.fnDraw();
        tbl.fnAddData(dataSet);


        //$('#test').DataTable().ajax.reload();

    }

推荐答案

您必须将数据表存储在变量中并添加行:看这里: https://jsfiddle.net/63235xk2/

You have to store your datatable in a variable and adding rows: Look here: https://jsfiddle.net/63235xk2/

$(document).ready(function ()
        {
            var dataSet = [];

            var datatable = $('#test').DataTable({
                data: dataSet,
                columns: [
                    { title: "Name" },
                    { title: "Position" },
                    { title: "Office" },
                    { title: "Extn." },
                    { title: "Start date" },
                    { title: "Salary" }
                ]
            });


      $('.asd').on('click',function(){
                dataSet = [
                    ["Tiger Nixon", "System Architect", "Edinburgh", "5421", "2011/04/25", "$320,800"],
                    ["Garrett Winters", "Accountant", "Tokyo", "8422", "2011/07/25", "$170,750"],
                    ["Ashton Cox", "Junior Technical Author", "San Francisco", "1562", "2009/01/12", "$86,000"],
          ];

        alert(dataSet.length);

          datatable.clear();
          datatable.rows.add(dataSet);
          datatable.draw();
      });

        });
