Question

我有一个Object，它包含每个产品变体的配置，基本上我希望能够搜索哪个对象有2个特定值，然后获取它的v_id值，只有1个结果。

代码：

//object
product_1: {
  p_id: 11, // Pendant Conicol
  variants: {
    v_1: { v_id:397, color:"gold", size:"20|30" },
    v_2: { v_id:396, color:"gold", size:"20|40" },
    v_3: { v_id:395, color:"gold", size:"20|50" },
    v_4: { v_id:394, color:"gold", size:"25|25" }
  }
}

getVariantId: function() {
  var results = []; // There will only be 1 result so maybe dont need array?
  var searchFor = "gold and 20|50";
  //Loop here?
  console.log(results.v_id);
}

Answer 1

var results = Object.keys(product_1.variants).map(function (key) {
    return product_1.variants[key];
}).filter(function (object) {
    return object.color === 'gold' && object.size === '20|50';
});

其中product_1.variants是对variant对象的引用。

Answer 2

var  product_1 = {
      p_id: 11, // Pendant Conicol
      variants: {
        v_1: { v_id:397, color:"gold", size:"20|30" },
        v_2: { v_id:396, color:"gold", size:"20|40" },
        v_3: { v_id:395, color:"gold", size:"20|50" },
        v_4: { v_id:394, color:"gold", size:"25|25" }
      }
    }

function search(obj,str){
  // remove space from str 
  str = str.replace(/\s/g,'');

  var params = str.split('and');


  var res = [];

 for(item in obj){ 
    if(obj.hasOwnProperty(item) && obj[item].color == params[0] && obj[item].size == params[1]
    ){
          res.push(obj[item]);
    }
 }

  // return the first item id or empty string if not found
  // can do something like this :       
  return (res.length)?res[0].v_id:'';
}

console.log(search(product_1.variants,'gold and 25|25')); // output: 394

Answer 3

function getVariantId(prodObj, searchFor) {
  //i.e. var searchFor = "gold and 20|50"
  var cond = searchFor.split(' and ')
  for(key in prodObj.variants) {
    if (prodObj.variants[key].color === cond[0] && prodObj.variants[key].size === cond[1]) return key
  }
}

搜索包含2个值的对象的对象？
