对象数组组合

需求： 将
var priceOption = {
age:[18,20],
sex:['男','女'],
hc:['2-6人','7-8人']
}
上述对象中age与sex及hc自由组合：得到如下形式：
{age: 18, sex: "男", hc: "2-6人"}
{age: 18, sex: "男", hc: "7-8人"}
{age: 18, sex: "女", hc: "2-6人"}
{age: 18, sex: "女", hc: "7-8人"}
{age: 20, sex: "男", hc: "2-6人"}
{age: 20, sex: "男", hc: "7-8人"}
{age: 20, sex: "女", hc: "2-6人"}
{age: 20, sex: "女", hc: "7-8人"}

代码如下

 
var priceFactor=['age','sex','hc']
var priceOption = {
    age:[18,20],
    sex:['男','女'],
    hc:['2-6人','7-8人']
}
   
function plzhFirst(datas){
       var array = [];
       var propObj = getFirstProp(datas);
       var propName= propObj.name;
       var propValue=propObj.value;
       if(_.isArray(propValue)){
          for(var i = 0 ;i<propValue.length;i++){
             var newObj = {};
             newObj[propName]=propValue[i];
             array.push(newObj);
          }
       }else{
          var newObj ={};
          newObj[propName]=propValue;
          array.push(newObj) 
       }
       for(var i=1;i<priceFactor.length;i++){
          array = plzh(array,priceOption[priceFactor[i]],priceFactor[i])
       }
       return array
       
 }

function getFirstProp(obj){
    var propObj = {}
    for(var i in obj){
        propObj.name=i;
        propObj.value=obj[i];
        return propObj;
     }
}


function plzh(arr1,arr2,nextAttr){
    var array = [];  
    for(var i=0;i<arr1.length;i++)  
     {  
            var obj = arr1[i];  
            for(var j=0;j<arr2.length;j++)  
            {  
                var newObj= _.cloneDeep(obj);
                var v2 = arr2[j]; 
                newObj[nextAttr]=v2;
                array.push(newObj);
            };  
      };  
     return array;  
}

var  endData =console.log(plzhFirst(priceOption));
