问题
Does anyone know a way to get live - or 20 minutes delayed - stock quotes using javascript? I looked at the google api at http://code.google.com/apis/finance/docs/finance-gadgets.html but it was very hard to get a working example.
has anyone got it to work to get quote for any stock, or found a better way ?
thank you.
回答1:
It took awhile but here is working code that uses Yahoo!'s YQL and jQuery:
<script type="text/javascript" src="jquery-1.5.1.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var symbol='goog';
var callback = function(data) {
var price=data.query.results.span[0].content;
alert('Stock Price: ' + price);
};
var url = 'http://query.yahooapis.com/v1/public/yql';
// this is the lovely YQL query (html encoded) which lets us get the stock price:
// select * from html where url="http://finance.yahoo.com/q?s=goog" and xpath='//span[@id="yfs_l10_goog"]'
var data = "q=select%20*%20from%20html%20where%20url%3D%22http%3A%2F%2Ffinance.yahoo.com%2Fq%3Fs%3D" + symbol + "%22%20and%20xpath%3D'%2F%2Fspan%5B%40id%3D%22yfs_l10_" + symbol + "%22%5D'&format=json";
$.getJSON(url, data, callback);
});
</script>

to insert finance Javasript quotes into html, you can check into the webmaster section of Forexpros. You just have to copy/past the code, and their finance charts are of high quality. I used them for my website.

A jQuery stock quotes plugin, jquery-stockquotes, could be of use here
Twitter: <span class="stock-quote" data-symbol="TWTR"></span>
Facebook: <span class="stock-quote" data-symbol="FB"></span>
Google: <span class="stock-quote" data-symbol="GOOGL"></span>
Netflix: <span class="stock-quote" data-symbol="NTFLX"></span>
Yahoo: <span class="stock-quote" data-symbol="YHOO"></span>
<script>
$('.stock-quote').stockQuotes();

There is a new library I created called stocks.js, it provides an easy to use stock market API that can fetch live stock data (refreshed every minute). The source of the data is Alpha Vantage.
An example of usage would be:
// Let's get the stock data of Tesla Inc. for the last 10 minutes
var result = stocks.timeSeries({
symbol: 'TSLA',
interval: '1min',
amount: 10
});

This code pulls multiple stocks information from Yahoo Finance. No plugin needed, only using jQuery. I got the rest end point at https://developer.yahoo.com/yql/console/ , under the community table yahoo.finance.quote.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

$.each(data.query.results.quote, function(i, value){

})
alert(results);
};
var url = "https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quote%20where%20symbol%20in%20("
