实现两个文件同步读取

//实现两个文件一起读取var getCsv = function (csvUrl) {    var defer = $.Deferred();    d3.csv(csvUrl, function (error, rows) {        if (error) {            defer.reject(error);        }        defer.resolve(rows);    });    return defer.promise();};var getJson = function (jsonUrl) {    var defer = $.Deferred();    d3.json(jsonUrl, function (error, rows) {        if (error) {            defer.reject(error);        }        defer.resolve(rows);    });    return defer.promise();};$.when(    getCsv("data/info.csv"), // please pass csv url as you like    getJson("data/test.json")  // please pass csv url as you like).done(function (infodata,data) {    drawforce(data,infodata);        datemp=data    return datemp;    console.log("11",infodata)   // readInfo(infodata);}).fail(function (err) {    console.log(err);});
