两个数组的排序方法

  var arr=['s','m','l','xl'];

    var list=['白色','红色','蓝色','黑色'];

    转化成多个SKU(如下):

    [

    {color:"白色",

    size:"s"},

   {color:"白色",

    size:"m"},

   {color:"白色",

    size:"l"},

   {color:"白色",

    size:"xl"},

    .......

]

    for(var i=0,a=[];i<arr.length;i++){

        for(var j=0;j<list.length;j++){

                var b={};

                b.size=arr[i];

                b.color=list[j]

                a.push(b)

        }

    }

    console.log(a)
