嗨，我是 javascript 新手，我编写了一个 javascript 代码供用户下载两个 .csv 文件 1）下载等待时间报告和 2）下载原始等待时间报告 下面是 javascript 代码：

$(document).ready(function () {
        <?php $array =     

getCompiledRawDataForAverageWaitTimeStatisticOfMerchant($startDate, $endDate,  

$merchantID, $paxStart, $paxEnd);




        array_unshift($array,array("transactionID"=>"transactionID","merchantID"=>"merchantID","mobileNum"=>"mobileNum","capacity"=>"capacity","remarks"=>"remarks","queueStartTime"=>"queueStartTime","status"=>"status","statusTime"=>"statusTime","numPings"=>"numPings","minTime"=>"minTime","time before ping"=>"time before ping","day"=>"day"));?>
        var items = <?php 
        echo json_encode($array);?>;
        console.log(items);



        var jsonObject = JSON.stringify(items);
        var csv = ConvertToCSV(jsonObject);

        a=document.createElement('a');
        a.textContent='Download Waiting Time Report';
        a.download="waitTime.csv";
        a.href='data:text/csv;charset=utf-8,'+escape(csv);
        document.body.appendChild(a);
        ///Second thing to code:
        //document.write("\n");

        <?php $array2 =  

  getAllRawDataForAverageWaitTimeStatisticOfMerchant($startDate, $endDate, $merchantID, 

   $paxStart, $paxEnd);



 array_unshift($array2,array("transactionID"=>"transactionID","merchantID"=>"merchantID","mobileNum"=>"mobileNum","capacity"=>"capacity","remarks"=>"remarks","queueStartTime"=>"queueStartTime","final status"=>"final status","final statusTime"=>"final statusTime","status"=>"status","minTime"=>"minTime","numPings"=>"numPings","time before status change"=>"time before status change","day"=>"day"));?>
        var items2 = <?php 
        echo json_encode($array2);?>;
        console.log(items2);



        var jsonObject2 = JSON.stringify(items2);
        var csv2 = ConvertToCSV(jsonObject2);

        a=document.createElement('a');
        a.textContent='Download Raw Waiting Time Report';
        a.download="RawWaitTime.csv";
        a.href='data:text/csv;charset=utf-8,'+escape(csv2);
        document.body.appendChild(a);


    });

请帮助每次我尝试插入断行语句时，控制台都会读取错误

将a元素放在p元素中，然后将p元素附加到页面。 

 function appendLink() { 
        a=document.createElement('a');
        a.textContent='Download Waiting Time Report';
        a.download="waitTime.csv";
        a.href='data:text/csv;charset=utf-8,';
        var div = document.createElement('p');
        div.appendChild(a);
        document.body.appendChild(div);
    }

在此处查看实际操作：http: //jsfiddle.net/kQTMY/1/

br标签会起作用，但 MDN 建议使用p元素，因为换行符不像在地址或诗歌中那样具有重要意义。 https://developer.mozilla.org/en-US/docs/Web/HTML/Element/br

你可以尝试写：

document.body.appendChild(document.createElement('br'));

而不是使用

document.write("\n");
