js 导出csv格式文件，并且处理逗号

js 导出csv格式文件，如果字段中存在逗号，将整个字段拼接上引号：如下
if(!Curent_noflyZoneList||Curent_noflyZoneList.length==0){
layerOpen(“没有可导出的数据！”);
return;
}
var obj={};
obj.title=[“序号”,“禁飞区名称”,“类型”,“半径”,“起始方位”,“截止方位”,“长度”,“宽度”,“离地高度”,“海拔高度”,“位置点”,“备注”];
obj.titleForKey=[“number”,“name”,“type”,“round_radius”,“sector_startLocation”,“sector_endLocation”,“ellipse_length”,“ellipse_width”,“height”,“altitude”,“locationList”,“remarks”];
var dataTmp=[];
for(let k in Curent_noflyZoneList){
let data={};
data.number=k+1;
data.name=Curent_noflyZoneList[k].name;
data.type=“多边形”;
data.round_radius="";
data.sector_startLocation="";
data.sector_endLocation="";
data.ellipse_length="";
data.ellipse_width="";
data.height=Curent_noflyZoneList[k].height;
data.altitude=Curent_noflyZoneList[k].altitude;
data.remarks=“多边形至少3个点”;
let locationListTmp=Curent_noflyZoneList[k].locationList;
let list="";
if(locationListTmp&&locationListTmp.length>0){
list=locationListTmp[0].longitude+","+locationListTmp[0].latitude;
if(locationListTmp.length>2){
for(let j=1;j< locationListTmp.length;j++){
let lngLat =locationListTmp[j].longitude+","+locationListTmp[j].latitude;
list=list+";"+lngLat;
}
}

    }
    //这么处理，前面加引号的转义，末尾也加上，就行了
    data.locationList="\""+list+"\"";
    dataTmp.push(data);
}
obj.data=dataTmp;
