jquery multi-asynchronous management usage records

　　$.when() passes multiple deferred

var ajaxBatch=[];
//构建deferred数组
...
$.when.apply($,ajaxBatch).done();

　 done() The argument structure in the callback is inconsistent

　There will be three situations:

　No parameters

$.when()一个deferred参数: [data, textStatus , jqXHR] #假定 x代表[data,textStatus,jqXHR]结构
$.when()多个deferred参数: [x1,x2,x3]

　Are you drunk? How to handle it uniformly? ?

Currently using the structure to determine the innermost data

.done(function(){
var params=[].slice.call(arguments);
if(typeof params[0][0] !='object'){ //第二种情况返回undefined
params=[];
params[0]=[].slice.call(arguments);
}
//然后遍历结果吧
});
