JavaScript将array数据下载到Excel中- 惊觉

具体代码如下：

    <title>下载Excel</title>

<body>
    <button onclick="downloadfile()">下载Excel</button>
    <script>
        function downloadfile() {
            
            var workbook = XLSX.utils.book_new(); //这段代码创建了一个名为的Workbook对象。
            console.log(workbook)
            var ws = XLSX.utils.json_to_sheet([]); //创建一个工作表对象
            var ws1 = XLSX.utils.json_to_sheet([]); //创建一个工作表对象
            XLSX.utils.book_append_sheet(workbook,ws,"ph数据"); //将工作表添加到workbook对象中
            XLSX.utils.book_append_sheet(workbook,ws1,"test"); //将工作表添加到workbook对象中

            workbook.creator = 'test123'  //创建者
            workbook.created = new Date()  //创建时间

            var data = [

                {"bz":"","cqqk":"/","date":"2023-01-04","djperson":"zs","id":1,"name":"2#","ph":5.8},{"bz":"","cqqk":"/","date":"2023-01-04","djperson":"zs","id":2,"name":"3#","ph":5.06}
            ]
            var jsonDataWithHeaders = [
                { "header1": "value1", "header2": "value2" },
                { "header1": "value3", "header2": "value4" }
                ];
            var datas = []
            for(var i = 0;i < data.length; i++){
                var p = {"id":data[i].id,"date":data[i].date,"name":data[i].name,"ph":data[i].ph,"cqqk":data[i].cqqk,"djperson":data[i].djperson,"bz":data[i].bz}
                datas.push(p)
            }
            //
            //将数据添加到工作表
            XLSX.utils.sheet_add_json(ws,datas,{skipHeader:false,origin:"A1"})
            XLSX.utils.sheet_add_json(ws1,jsonDataWithHeaders,{skipHeader:true,origin:"A2"})
            var date = new Date();
            var isoString = '导出数据'+ date.toISOString().slice(0,10);
            // console.log(p);
            // const date = new Date();
            // // 获取年份
            // const year = date.getFullYear().toString();    
            // // 获取月份，月份从0开始，需要加1
            // const month = (date.getMonth() + 1).toString(); 
            // // 获取日期
            // const day = date.getDate().toString();
            // 获取小时
            const hours = date.getHours().toString().padStart(2, '0');
            // 获取分钟padStart(2, '0')在前面补0
            const minutes = date.getMinutes().toString().padStart(2, '0');
            // 获取秒数
            const seconds = date.getSeconds().toString().padStart(2, '0');
            var sfm = hours+':'+minutes+':'+seconds
            var names = isoString+' '+sfm+'.xlsx'
            console.log(names);
            //导出Excel文件
            XLSX.writeFile(workbook,names)
        }
    </script>
</body>

这个建了一个Excel表，两个sheet，分别存放了一定的数据，最后进行下载下来，其中skipHeader:false,origin:"A1"代表不省略表头，表头默认是字典中的keys，从A1行开始：
