You can use JSONP for making such requests, but i think the url you are trying to access does not have JSONP feature. Since you want the exchange rates (i guess as per the url you are trying to use), you could use:
您可以使用 JSONP 来发出此类请求，但我认为您尝试访问的 url 没有 JSONP 功能。由于您想要汇率（我猜根据您尝试使用的网址），您可以使用：
$(document).ready(function(){
$.ajax({
url: 'http://openexchangerates.org/latest.json',
dataType: 'jsonp',
success: function(json) {
// Rates are in `json.rates`
// Base currency (USD) is `json.base`
// UNIX Timestamp when rates were collected is in `json.timestamp`
rates = json.rates;
base = json.base;
console.log(rates);
}
});
});

This should work with jQuery:
这应该适用于jQuery：
$.ajax({
url: 'https://raw.github.com/currencybot/open-exchange-rates/master/latest.json',
dataType: 'jsonp',
success: function (data, textStatus, jqXHR) {
//the variable 'data' will have the JSON object
// In your example, the following will work:
alert(data.disclaimer);
error: function(jqXHR, textStatus, errorThrown) {
//Error handling code
alert('Oops there was an error');
}
}
});
