将数组按照个数进行分组

服务端返回的是个数组,界面需要能滑动,每个滑动区块都是八个,所以要将数组进行分组.

//1.数据

var data=[

{cateName:'手机'},

{cateName:'手机'},

{cateName:'手机'},

{cateName:'手机'},

{cateName:'手机'},

{cateName:'手机'},

{cateName:'手机'},

{cateName:'手机'},

{cateName:'手机'},

{cateName:'手机'}

];

againGroup (data,num){

　　var result=[];

　　for(var i=0,len=data.length;i<len;i+=num){

　　　　result.push(data.slice(i,i+num));

　　}

　　return result;

}

againGroup(data,8);//数组就按照8个进行分组了;
