javascript - 在javascript中遍历对象寻找嵌套属性并返回找到的对象

Question

我想编写一个函数来检查关键字是否包含在对象属性数组中。如果在该数组中找到关键字，它应该返回该对象。

我试过下面的代码，但它不起作用。我希望有聪明的人可以告诉我我在这段代码中做错了什么:)

我的目标是函数:Projects.detectProjectByKeyword("brumi") 返回 ImageObjects.DE.brumi

或者也许有更简单的方法来实现目标？我非常感谢任何帮助，因为我已经被困在这里一个多星期了:(

var ImageObjects = function() {
  var DE = {
      brumi : {
        name:"Brummi-Werk",
        keywords: ["brumi","auto", "LKWs", "lkws","lkw-werkstatt","die Brummis"]
    },
      medien : {
        name: "medien",
        keywords:["vier","nummer vier", "springer", "neue medien", "neue medien ag", "die neue medien ag"]
    },
      mautmaxe : {
        name: "mau",
        keywords:["fünf","nummer fünf", "mautmaxe", "maut", "currywust", "currywurst stand"]
      }
  };

  return {
    DE: DE
  }

}();

 function searchObj(obj, query) {
    var data ='';
    for (var property in obj) {
      if (obj.hasOwnProperty(property)) {
        if (typeof obj[property] === "object") {
         data = searchObj(obj[property], query);
          if(data !='') return data;
        }
        else {
          if (obj["keywords"].indexOf(query) >= 0) {
            return  obj;
          }
          else {
              return null;
          }
        }
      }
    }

    return data;
  }

var Projects = function() {

    function detectProjectByKeyword(project) {

        var foundObject = null;

        for (var x in ImageObjects.DE){
            if ((searchObj(ImageObjects.DE[x], project))!=null){
                foundObject = searchObj(ImageObjects.DE[x], project)
            }

        }
        return foundObject;

    }

  return {
    detectProjectByKeyword: detectProjectByKeyword
  }
}();

如果结构永远不变，IE； ImageObjects.LANGUAGE.project.keywords，这就足够了:

function detectProjectByKeyword(keyword, obj, language) {
  for(var a in obj[language]) {
    if(obj[language].hasOwnProperty(a)) {
      if(obj[language][a].keywords.indexOf(keyword) >= 0) return obj[language][a]
    }
  }
}

console.log(detectProjectByKeyword('brumi', ImageObjects, 'DE'));
console.log(detectProjectByKeyword('lkws', ImageObjects, 'DE'));
console.log(detectProjectByKeyword('mautmaxe', ImageObjects, 'DE'));
