vue.js/reactjs下载文件

vue.js, reactjs 一般，使用js来下载文件。
而，后段一般返回数据流。
这时候，IE用Blob处理，chrome创建个超连接来处理.

s.handleBlob=function(data,fileName){
   var blob = new Blob([data],{type: 'application/[图片][图片]vnd.ms-excel'});
   let name=fileName+'-'+s.transferTimeToString(new Date())+'.xls';//扩展名
    if('msSaveOrOpenBlob' in navigator){//兼容ie
        window.navigator.msSaveOrOpenBlob(blob,name);
    }else{
        let downLoadAllUrl =window.URL.createObjectURL(blob);
        var eleLink = document.createElement('a');
        eleLink.download = name;
        eleLink.style.display = 'none';
        eleLink.href = downLoadAllUrl;
        document.body.appendChild(eleLink);
        eleLink.click();
        document.body.removeChild(eleLink);
    }
}

    fetch(exportBillURL, newOptions).then(response => response.blob())
        .then(blob => {
            if (window.navigator.msSaveBlob){
                try{
                    var blobObject = new Blob([blob]);
                    window.navigator.msSaveBlob(blobObject, "billing.csv");
                }catch(e){
                    console.log(e);
                }
            }else{
                var url = window.URL.createObjectURL(blob);
                var a = document.createElement('a');
                document.body.appendChild(a);
                a.style.display = 'none';
                a.href = url;
                a.download = "billing.csv";
                a.click();
            }
        });
