}

我无法得到之前的答案来做我想要的事情。

在玩弄了这里的其他回复之后，我做了这个。它很粗糙，但很管用！

对于此对象：

var myObj = {
    pageURL    : "BLAH",
    emailBox   : {model:"emailAddress", selector:"#emailAddress"},
    passwordBox: {model:"password"    , selector:"#password"}
};

…此代码：

// Get every value in the object into a separate array item ...
function buildArray(p_MainObj, p_Name) {
    var variableList = [];
    var thisVar = "";
    var thisYes = false;
    for (var key in p_MainObj) {
       thisVar = p_Name + "." + key;
       thisYes = false;
       if (p_MainObj.hasOwnProperty(key)) {
          var obj = p_MainObj[key];
          for (var prop in obj) {
            var myregex = /^[0-9]*$/;
            if (myregex.exec(prop) != prop) {
                thisYes = true;
                variableList.push({item:thisVar + "." + prop,value:obj[prop]});
            }
          }
          if ( ! thisYes )
            variableList.push({item:thisVar,value:obj});
       }
    }
    return variableList;
}

// Get the object items into a simple array ...
var objectItems = buildArray(myObj, "myObj");

// Now use them / test them etc... as you need to!
for (var x=0; x < objectItems.length; ++x) {
    console.log(objectItems[x].item + " = " + objectItems[x].value);
}

…在控制台中生成：

myObj.pageURL = BLAH
myObj.emailBox.model = emailAddress
myObj.emailBox.selector = #emailAddress
myObj.passwordBox.model = password
myObj.passwordBox.selector = #password

在我的情况下（基于前面的内容），任何数量的级别都是可能的。

var myObj = {
    rrr: undefined,
    pageURL    : "BLAH",
    emailBox   : {model:"emailAddress", selector:"#emailAddress"},
    passwordBox: {model:"password"    , selector:"#password"},
    proba: {odin:{dva:"rr",trr:"tyuuu"}, od:{ff:5,ppa:{ooo:{lll:'lll'}},tyt:'12345'}}
};


function lookdeep(obj,p_Name,gg){
    var A=[], tem, wrem=[], dd=gg?wrem:A;
    for(var p in obj){
        var y1=gg?'':p_Name, y1=y1 + '.' + p;
        if(obj.hasOwnProperty(p)){
           var tem=obj[p];
           if(tem && typeof tem=='object'){
               a1=arguments.callee(tem,p_Name,true);
               if(a1 && typeof a1=='object'){for(i in a1){dd.push(y1 + a1[i])};}
            }
            else{
               dd.push(y1 + ':' + String(tem));
            }
        }
    };
    return dd
};


var s=lookdeep(myObj,'myObj',false);
for (var x=0; x < s.length; ++x) {
console.log(s[x]+'\n');}

结果：

["myObj.rrr:undefined",
"myObj.pageURL:BLAH",
"myObj.emailBox.model:emailAddress",
"myObj.emailBox.selector:#emailAddress",
"myObj.passwordBox.model:password",
"myObj.passwordBox.selector:#password",
"myObj.proba.odin.dva:rr",
"myObj.proba.odin.trr:tyuuu",
"myObj.proba.od.ff:5",
"myObj.proba.od.ppa.ooo.lll:lll",
"myObj.proba.od.tyt:12345"]

var validation_messages = {
    "key_1": {
        "your_name": "jimmy",
        "your_msg": "hello world"
    },
    "key_2": {
        "your_name": "billy",
        "your_msg": "foo equals bar"
    }
}
for (var i in validation_messages) {
    console.log("i = \"" + i + "\"");
    console.log("validation_messages[\"" + i + "\"] = ");
    console.log(validation_messages[i]);
    console.log("\n");
    for (var j in validation_messages[i]) {
        console.log("j = \"" + j + "\"");
        console.log("validation_messages[\"" + i + "\"][\"" + j + "\"] = \"" + validation_messages[i][j] + "\"");
        console.log("\n");
    }
    console.log('\n');
}

输出：

i = "key_1"
validation_messages["key_1"] = 
{
  your_name:"jimmy",
  your_msg:"hello world"
}

j = "your_name"
validation_messages["key_1"]["your_name"] = "jimmy"

j = "your_msg"
validation_messages["key_1"]["your_msg"] = "hello world"


i = "key_2"
validation_messages["key_2"] = 
{
  your_name:"billy",
  your_msg:"foo equals bar"
}

j = "your_name"
validation_messages["key_2"]["your_name"] = "billy"

j = "your_msg"
validation_messages["key_2"]["your_msg"] = "foo equals bar"

在ECMAScript 5下，可以组合Object.keys（）和Array.protocol.forEach（）：

变量obj={第一个：“约翰”，上一个：“Doe”};////访问非继承的可枚举密钥//Object.keys（obj）.forEach（函数（键）{console.log（key，obj[key]）；});
