Question

我收到了以下代码：

var url = 'https://lottery.lafunda.com.do/Lottery/WinningNumbers?key=664cf843-8904-4212-9503-d4733651f519&gobackdays=2&grouped=true&language=es-DO&callback=generateTicker';
$.ajax({
    url: url,
    accept: "application/javascript",
    dataType: "jsonp"
});



function generateTicker(returndata) {
  console.log(returndata);
}

但没有任何反应。在控制台中我收到此消息：＆＃34;资源被解释为脚本，但使用MIME类型text / html＆＃34;

进行传输

这是JSfiddle：http://jsfiddle.net/8k8souqj/

提前致谢。

修改

你们大多数人都指出URL没有返回有效的json。但是，如果我对chrome使用修改标头扩展并接受＆＃34; application / javascript＆＃34;作为标题我得到有效的javascript：

 generateTicker([{"HouseAbbreviation":"LIL","ClosesOn":"2014-10-15T02:10:00","HouseName":"Illinois Noche","Drawings":[{"HouseAbbreviation":"LIL","HouseName":"Illinois Noche","ClosesOn":"2014-10-15T02:10:00","BallCount":2,"PostedNumbers":"3-0"},{"HouseAbbreviation":"LIL","HouseName":"Illinois Noche","ClosesOn":"2014-10-15T02:10:00","BallCount":3,"PostedNumbers":"6-3-0"}... etc

编辑2：

显然问题是jsonp不能使用修改的头文件，因为这不可能通过脚本标记。因此，URL将始终返回html。感谢所有

该代码提取HTML页面：

Answer 2

回调永远不会以这种方式运作。您必须将回调添加到ajax请求。

var url = 'https://lottery.lafunda.com.do/Lottery/WinningNumbers?key=664cf843-8904-4212-9503-d4733651f519&gobackdays=2&grouped=true&language=es-DO&callback=generateTicker';
$.ajax({
    url: url,
    accept: "application/javascript",
    dataType: "jsonp",
    success: generateTicker
});

function generateTicker(returndata) {
  console.log(returndata);
}

Answer 3

你的问题是两个错误的结合，正如Jerodev所说，你调用回调方法的方式不起作用，而且，你提到的发送接受标头的方式也不合适

以下内容应该有效

$.ajax({
    headers: {
        Accept: "application/javascript"
    },
    url: url,
    data: "jsonp",
    success : generateTicker
})

function generateTicker(returndata) {
    console.log(returndata);
}
