不幸的是，jQuery没有此功能。
很高兴，您可以自己轻松实现它。
var url = 'http://gdata.youtube.com/feeds/api/videos/{{vid}}?v=2&alt=json';function getVideo(vid){ var u = url.replace('{{vid}}', vid); return $.getJSON( u ).then(function(res){ return {video:vid,result:res.entry}; });}var promises = ['ozj2-bnTL3s','EAZ4Tlt8MQ4',"doesn'texist"].map(getVideo);some(promises).then(function(results){ for(var i = 0; i < results.length; i++) { console.log(results[i]); // log }});// get a hook on when all of the promises resolve, some fulfill// this is reusable, you can use this whenever you need to hook on some promises// fulfilling but all resolving.function some(promises){ var d = $.Deferred(), results = []; var remaining = promises.length; for(var i = 0; i < promises.length; i++){ promises[i].then(function(res){ results.push(res); // on success, add to results }).always(function(res){ remaining--; // always mark as finished if(!remaining) d.resolve(results); }) } return d.promise(); // return a promise on the remaining values}这是结果的有效JSFiddle。
