Question

用于创建包含其中值的csv文件的代码：

function exportTableToCSV($table, filename) {
alert(filename);
var $rows = $table.find('tr:has(td)'),

 // Temporary delimiter characters unlikely to be typed by keyboard
        // This is to avoid accidentally splitting the actual contents
        tmpColDelim = String.fromCharCode(11), // vertical tab character
        tmpRowDelim = String.fromCharCode(0), // null character

        // actual delimiter characters for CSV format
        colDelim = '","',
        rowDelim = '"\r\n"',

        // Grab text from table into CSV formatted string
        csv = '"' + $rows.map(function (i, row) {
            var $row = $(row),
                $cols = $row.find('td');

            return $cols.map(function (j, col) {
                var $col = $(col),
                    text = $col.text();

                return text.replace(/"/g, '""'); // escape double quotes

            }).get().join(tmpColDelim);

        }).get().join(tmpRowDelim)
            .split(tmpRowDelim).join(rowDelim)
            .split(tmpColDelim).join(colDelim) + '"',

        // Data URI
        csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);
        alert(csvData);
    $(this)
        .attr({
        'download': filename,
            'href': csvData,
            'target': '_blank'
    });
}

点击按钮后会使用以下代码，该按钮会将数据导出到csv文件。

$(".Approve").on('click', function (event) {       
    var that = this; // need to capture `this` context, it doesn't carry into the timer context
 setTimeout(function () {
 exportTableToCSV.apply(that, [ $('#myDiv>table'), 'XYZ.csv'   ]);
 }, 10 * 100);     
  });

});

我已应用更改，现在Timeout正在运行，但XYZ.csv无法下载数据。

exportTableToCSV.apply已经执行了该功能。您将该功能的输出放在计时器中。

请改为：

var that = this; // need to capture `this` context, it doesn't carry into the timer context
setTimeout(function () {
    var result = exportTableToCSV.apply(that, [ $('#myDiv>table'), 'ExportedBoxResult.csv' ]);
    console.log(result);
}, 10 * 1000);

exportTableToCSV.apply(this[$('#myDiv>table'),'ExportedBoxResult.csv']);

语法错误，括号无法正确匹配。你打算做什么：？

exportTableToCSV.apply(this, [ $('#myDiv>table'), 'ExportedBoxResult.csv' ]);
