將數組按照個數進行分組

服務端返回的是個數組,界面需要能滑動,每個滑動區塊都是八個,所以要將數組進行分組.

//1.數據

var data=[

{cateName:'手機'},

{cateName:'手機'},

{cateName:'手機'},

{cateName:'手機'},

{cateName:'手機'},

{cateName:'手機'},

{cateName:'手機'},

{cateName:'手機'},

{cateName:'手機'},

{cateName:'手機'}

];

 

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);//數組就按照8個進行分組了;
