循环组合{"item1":"aa,bb","item2":"M,L"}

Question

js怎么将{"item1":"aa,bb","item2":"M,L"}组合成[{"item1":"aa","item2":"M"},{"item1":"aa","item2":"L"},{"item1":"bb","item2":"M"},{"item1":"bb","item2":"L"}]

Answer 1

var data = {"item1":"aa,bb","item2":"M,L"};

var allArr = [];

var arr = data.item1.split(","),

    arr1 = data.item2.split(",");

for(var i=0;i<arr.length;i++){

       for(var j=0;j<arr1.length;j++){

            allArr.push({item:arr[i],item2:arr1[j]})

        }

}

console.log(JSON.stringify(allArr));
