$.ajax( { url : '', data: {}, dataType:'jsonp',  jsonpCallback: 'callbackName', type: 'post'
        ,success:function (data) {
        console.log('ok');
        },
        error:function () {
        console.log('error');
        }
        });

我如何写相同的功能在纯JS？

How do I write the same functionality in pure JS?

推荐答案

在这种特殊情况下，你是不是做一个Ajax调用所有，而不是你正在做一个JSONP请求。幸运的是，这些都是非常容易复制，并适用于所有的浏览器。

In this particular case, you aren't making an ajax call at all, instead you're making a JSONP request. Luckily, these are incredibly easy to replicate and work in all browsers.

var s = document.createElement("script"),
    callback = "jsonpCallback_" + new Date().getTime(),
    url = "http://forexplay.net/ajax/quotes.php?callback=" + callback;
window[callback] = function (data) {
    // it worked!
    console.log(data);
};
s.src = url;
document.body.appendChild(s);
