I posted this question AJAX URL update as I thought the problem with my code was with AJAX but I think this could be an issue with HighStocks.
I have an external .js file with these functions:
//uses AJAX call to retrieve data and then creates the chart with the data
function createChart(ticker) {
$.ajax({
type: 'post',
url: 'http://...' + ticker + '....com',
success: function (data, status) {
//chart is rendered in here
}
//gets the user inputted ticker symbol from a HTML input box
// and passes to chart function
function getTicker() {
var ticker = document.getElementById('userInput').value;
createChart(ticker);
}
My HTML file just has a simple form with an input box and a button that when clicked calls the getTicker function. For some reason the chart is not being created and the AJAX call doesnt seem to work.
Is this something with HighStocks maybe? Any suggestions would be appreciated.
UPDATE Thank you for the suggestions, I have attempted to use JSONP but the chart still does not load. Can anybody see what I am doing wrong?
var closePrices = new Array();
var dateArray = new Array();
var timeStampArray = new Array();
var timeClose = new Array();
function jsonCallback(data, ticker) {
console.log( data );
//Put all the closing prices into an array and convert to floats
for(var i=0; i < data.query.results.quote.length; i++)
{
closePrices[i] = parseFloat( data.query.results.quote[i].Close );
}
//displays the values in the closePrices array
console.log( closePrices );
//Put all the dates into an array
for(var i=0; i < data.query.results.quote.length; i++)
{
dateArray[i] = data.query.results.quote[i].date;
}
//Convert all the dates into JS Timestamps
for(var i=0; i < dateArray.length; i++)
{
timeStampArray[i] = new Date( dateArray[i] ).getTime();
}
for(var i=0; i<data.query.results.quote.length; i++)
{
timeClose.push( [timeStampArray[i], closePrices[i]] );
}
timeClose = timeClose.reverse();
console.log ( timeClose );
//displays the dateArray
console.log( dateArray );
console.log( timeStampArray );
// Create the chart
$('#container').highcharts('StockChart', {
rangeSelector : {
selected : 1
},
title : {
text : ticker + ' Stock Price'
},
series : [{

data: timeClose,
