我发布了这个问题AJAX URL update因为我认为我的代码问题出在 AJAX 上,但我认为这可能是 HighStocks 的问题。
我有一个具有以下功能的外部 .js 文件:
//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);
}
我的 HTML 文件只有一个简单的表单,其中包含一个输入框和一个按钮,单击该按钮会调用 getTicker 函数。由于某种原因,未创建图表,并且 AJAX 调用似乎不起作用。
这可能是 HighStocks 的东西吗?任何建议,将不胜感激。
更新感谢您的建议,我尝试使用 JSONP,但图表仍然无法加载。谁能看到我做错了什么?
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
