javascript - Retrieving JSON data from API -

i trying simple stock api work on jsfiddle.net using quandl api: https://www.quandl.com/blog/api-for-stock-data

if use current ".csv" format below, returned csv file. if change format ".json" in api, how recover data can use on website example?

i believe need use getjson command, confused how works. can me out?

html:

<input type="text" id="symbol"> <button id="getprice">get price!</button> <div id="result">stock market ticker</div> 

javascript:

function getprice() {   var symbol = $("#symbol").val();    var baseurl = "https://www.quandl.com/api/v3/datasets/wiki/";   var stock = symbol+".csv";   var endurl = "column_index=4&rows=1&api_key='8mii36sd1q46ulgstklm";   var url = baseurl+ stock + "?" + endurl;    $("#result ").html("<a href = '" + url + "' >hyperlink</a>");  }  $("#getprice ").click(getprice); 

my output using stock ticker kors (.csv file) is: data close 1/5/2016 40.72

i've answered "how use quandl api?" following snippet, should adapt json:

var baseurl = "https://www.quandl.com/api/v3/datasets/wiki/"; var endurl = "column_index=4&rows=1&api_key='8mii36sd1q46ulgstklm"; var quandlcode = "kors"; // if it's choice? var url = baseurl + quandlcode + ".json?" + endurl; // dont forget "?" var xhr = new xmlhttprequest(); xhr.open("get", url, true); xhr.setrequestheader("content-type", "application/json"); xhr.onload = function() {     var data = json.parse(this.responsetext).dataset.data;     // {}.dataset.data data matrix in quandl     // datasets far know ...     // process own way } xhr.send();
