css:

html:

Js:

$(function(){        numAc('.kk','200','56','50')    ;    })        //  doc 对象    //  time  起始    //  seep  每次增加    //  index 时间    function numAc(doc,time,seep,index){         obj_text = parseInt($(doc).text());         obj = $(doc);         times = parseInt(time);        var time = setInterval(function(){            times = times+=parseInt(seep);            obj.html(times);            if(times >= obj_text){                clearInterval(time);                obj.removeClass('anmintate');                return false;            }        },index);    }

  改进后：

$(function(){        numAc('.kk','200','56','50','')    ;    })        //  doc 对象    //  time  起始    //  seep  每次增加    //  index 时间    //   num  最终数字  （可选项）  如果为空，会获取对象的INNerhtml        function numAc(doc,time,seep,index,num){        if(num){            obj_text = num ;        }else{             obj_text = parseInt($(doc).text());        }                 obj = $(doc);         times = parseInt(time);        var time = setInterval(function(){            times = times+=parseInt(seep);            obj.html(times);            if(times >= obj_text){                clearInterval(time);                obj.removeClass('anmintate');                return false;            }        },index);    }
