javascript中的JSON到CSV转换器：chrome中的问题

我正在使用JSON到CSV转换器库。代码是：

function JSONToCSVConvertor（JSONData，ReportTitle，ShowLabel）{

//If JSONData is not an object then JSON.parse will parse the JSON string in an Object
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;

var CSV = '';    
//Set Report title in first row or line

CSV += ReportTitle + '\r\n\n';

//This condition will generate the Label/Header
if (ShowLabel) {
    var row = "";

    //This loop will extract the label from 1st index of on array
    for (var index in arrData[0]) {

        //Now convert each value to string and comma-seprated
        row += index + ',';
    }

    row = row.slice(0, -1);

    //append Label row with line break
    CSV += row + '\r\n';
}

//1st loop is to extract each row
for (var i = 0; i < arrData.length; i++) {
    var row = "";

    //2nd loop will extract each column and convert it in string comma-seprated
    for (var index in arrData[i]) {
        row += '"' + arrData[i][index] + '",';
    }

    row.slice(0, row.length - 1);

    //add a line break after each row
    CSV += row + '\r\n';
}

if (CSV == '') {        
    alert("Invalid data");
    return;
}   

//Generate a file name
var fileName = "MyReport_";
//this will remove the blank-spaces from the title and replace it with an underscore
fileName += ReportTitle.replace(/ /g,"_");   

//Initialize file format you want csv or xls
var uri = 'data:text/csv;charset=utf-8,' + escape(CSV);

// Now the little tricky part.
// you can use either>> window.open(uri);
// but this will not work in some browsers
// or you will not get the correct file extension    

//this trick will generate a temp <a /> tag
var link = document.createElement("a");    
link.href = uri;

//set the visibility hidden so it will not effect on your web-layout
link.style = "visibility:hidden";
link.download = fileName + ".csv";

//this part will append the anchor tag and remove it after automatic click
document.body.appendChild(link);
link.click();
document.body.removeChild(link);

}

它在mozilla firefox中运行良好。它曾经在chrome中运行良好，但在几天之前，它无法以CSV格式下载。它只需将其下载到一个文件中，不带任何名称为＆＃34;下载＆＃34;的扩展名。它甚至不会占用我想要的文件名。
