尝试检查mootools中是否存在youtube视频时出错

Question

我有这个代码

 var x = 'http://gdata.youtube.com/feeds/api/videos/FLE2htv9oxc';
        var myJSONP = new Request.JSONP({
            url: x,
            callbackKey: 'jsoncallback',
            data: ({ partTag: is_youtube }),              
            onRequest: function (url) {
                // a script tag is created with a src attribute equal to url
            },
            onComplete: function (data) {
                // the request was completed.
                alert("ok");
            }
        }).send();

我试着验证youtube视频是否存在，我一直收到这个错误

缺少；此错误的语句中断前...ount='193‘viewCount='19488'/>

arrr..我做错了什么?有没有其他方法来验证url？

你需要告诉它使用v2和jsonp。按照原样，它返回xml...

var x = 'http://gdata.youtube.com/feeds/api/videos/FLE2htv9oxc?v=2&alt=jsonc';
var myJSONP = new Request.JSONP({
    url: x,
    log: true,
    onRequest: function(url) {
        // a script tag is created with a src attribute equal to url
    },
    onComplete: function(data) {
        // the request was completed.
        console.log(data);
    }
}).send();
