js懒加载异步操作解决办法

ajax分页请求后台数据事先定义一个number

var number = 0;

var getBonusPointsList = function(id,num,key,sign){

    var data2 = {        userId:id,        number:num,        accessKeyId:key,        sign:sign    };    data2 = JSON.stringify(data2);    $.ajax({        url:‘http://192.168.1.161:8080/user/getBonusPointsList‘,        type:‘POST‘,        data:data2,        /*header:{         ‘Access-Token‘:token         },*/        dataType : ‘json‘,        contentType: "application/json",        success:function(data){            if(data.result){                var html = ‘‘;                totalPages = data.totalPages;                totalElements = data.totalElements;                if(data.last){                    console.log(data.last);                    last = true;                }else {                    number = num+1;                }                for(var i =0; i<data.result.length; i++){                    var time1 = data.result[i].recordTime;                    var unixTimestamp = new Date(time1);                    var timeStr = unixTimestamp.getFullYear() + "-" + (unixTimestamp.getMonth() + 1) + "-" + unixTimestamp.getDate() + " " + unixTimestamp.getHours() + ":" + unixTimestamp.getMinutes();

html = "<li><div class=‘list_left listText‘><div class=‘list_time‘>"+timeStr+"</div><div>完成一次充电</div></div><div class=‘list_right listText‘>  +"+data.result[i].integralValue+"分 </div> </li>"

$("#intergral_ul").append(html);                }

}else{                console.log(data)

}

},        error:function(err){            //console.log(number)            alert(JSON.stringify(err))        }    });

}getBonusPointsList("2",0,"","");

使用number == number2解决异步请求造成的参数不同步问题：

//懒加载var number2 =1;$(window).scroll(function (event) {    event.stopPropagation();    event.preventDefault();    if($(window).scrollTop() + 10>= ($(document).height() - $(window).height()) ){

if(last){            console.log(last);

 }else if(number == number2){            console.log(number)            getBonusPointsList("2",number,"","");            number2++;        }

}
