Answer 1

The url returns a JSONP object. You can use the ajax function of jQuery to receive the data as an javascript object and do further work with it ...

$.ajax({
    url: "https://www.google.com/finance/info?q=NSE:NIFTY",
    dataType: "jsonp",
    success: function(response) {
        if (response.length) {
            for (i = 0, l = response.length; i < l; i++) {
                // example, log property 't' of each entry to the console
                console.log(response[i].t);
            }
        }
    }
});

Working example.

You will have to go through the data and generate the html for it.

You can use the getJSON function of jquery to fetch the data

$.getJSON('https://www.google.com/finance/info?q=NSE:NIFTY&callback=?', function(data){
     console.log(data[0]);
 });

Since its a jsonp we need to add the callback param in the url
