} 
} 

，这里是我的JavaScript文件

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); 
} 

，我传递一个JSON对象如前面我出，我得到的CSV文件还，但问题出现在seller_name和drop_seller中名称显示为[对象，对象]其余数据来对我认为这是因为这些值是在嵌套的JSON如何得到这些名称任何帮助请

Answer 1

如果我正确地理解你，你想只显示卖家名称，而不是它的每一个属性？

如果是这种情况，只需添加一个对象的检查，然后显示其名称。

for (var index in arrData[i]) { 
    var data = arrData[i][index]; 
    if(typeof data === 'object'){ 
     data = data.name; 
    } 
    row += '"' + data + '",'; 
}
