如何使用Jquery或Javascript将HTML表格数据作为json数据下载到.txt文件中。

让我们将您的任务分解为2个单独的任务，例如as-



1。将HTML表格转换为JSON数据

Let's break your task in to 2 separate tasks, such as-

1. Convert HTML table to JSON data

function tableToJson(table) {
    var data = [];

    // first row needs to be headers
    var headers = [];
    for (var i=0; i<table.rows[0].cells.length; i++) {
        headers[i] = table.rows[0].cells[i].innerHTML.toLowerCase().replace(/ /gi,'');
    }

    // go through cells
    for (var i=1; i<table.rows.length; i++) {

        var tableRow = table.rows[i];
        var rowData = {};

        for (var j=0; j<tableRow.cells.length; j++) {

            rowData[ headers[j] ] = tableRow.cells[j].innerHTML;

        }

        data.push(rowData);
    }

    return data;
}

window.focus();
