1.当两个ajax都执行完执行某函数

var getJson={            getData:function(data){                var defer = $.Deferred();                var result;                $.ajax({                    url:'http://datainfo.duapp.com/shopdata/getGoods.php',                    dataType:'jsonp',                    async:false,                    success:function(data){                        var html="";                        // $.each(data,function(i) {                        //     html+="
     
      
      
       "+data[i].className+"
      
      
       "+data[i].goodsID+"
      
      
     
"                        // });                        // $(".container").append(html);                        // result=true;                         result=data[0].className;                        console.log(result);                        defer.resolve(result);                          },                    error:function (XMLHttpRequest, textStatus, errorThrown){                          alert(XMLHttpRequest);                       }                 })                return defer.promise();                            },            getSome:function(res){                var defer = $.Deferred();                var result=false;                $.ajax({                    url:'http://datainfo.duapp.com/shopdata/getGoods.php',                    dataType:'jsonp',                    async:true,                    success:function(data){                        // var html="";                        // $.each(data,function(i) {                        //     html+="
     
      
      
       "+data[i].className+"
      
      
       "+data[i].goodsID+"
      
      
     
"                        // });                        // $(".container").append(html);                        // result=true;                         // console.log(result);                         result=data[8].className;                        console.log(result);                        defer.resolve(result);                           },                    error:function (XMLHttpRequest, textStatus, errorThrown){                          alert(XMLHttpRequest);                       }                 })                         return defer.promise();             }                 }         $.when(getJson.getData(),getJson.getSome()).done(function(res1,res2){                   setTimeout(function(){                    console.log(res1+" "+res2);                },1000);                })

2.当执行完1个异步函数后延迟执行另一个函数

var getJson={            getData:function(data){                var defer = $.Deferred();                var result;                $.ajax({                    url:'http://datainfo.duapp.com/shopdata/getGoods.php',                    dataType:'jsonp',                    async:false,                    success:function(data){                        var html="";                        $.each(data,function(i) {                            html+="
     
      
      
       "+data[i].className+"
      
      
       "+data[i].goodsID+"
      
      
     
"                        });                        $(".container").append(html);                        result=true;                         result=data[0].className;                        //console.log(result);                        defer.resolve(result);                          },                    error:function (XMLHttpRequest, textStatus, errorThrown){                          alert(XMLHttpRequest);                       }                 })                return defer.promise();                            },            getSome:function(res){                $.when(getJson.getData()).done(function(res1){                     console.log(res1);                    setTimeout(function(){                        $(".top").css("color","#ca2")                    },1000);                  })                            }                 }         // $.when(getJson.getData(),getJson.getSome()).done(function(res1,res2){           //         setTimeout(function(){        //             console.log(res1+" "+res2);        //         },1000);                // })        $("#btn").click(function(){            getJson.getSome();        })
