在console中保持简单，你可以使用逗号而不是+。+将尝试将对象转换为字符串，而逗号将在控制台中单独显示它。

例子:

var o = {a:1, b:2};
console.log(o);
console.log('Item: ' + o);
console.log('Item: ', o);   // :)

输出:

Object { a=1, b=2}           // useful
Item: [object Object]        // not useful
Item:  Object {a: 1, b: 2}   // Best of both worlds! :)

/*
    This function is as JSON.Stringify (but if you has not in your js-engine you can use this)
    Params:
        obj - your object
        inc_ident - can be " " or "\t".
        show_types - show types of object or not
        ident - need for recoursion but you can not set this parameter.
*/
function getAsText(obj, inc_ident, show_types, ident) {
    var res = "";
    if (!ident)
        ident = "";
    if (typeof(obj) == "string") {
        res += "\"" + obj + "\" ";

示例:

var obj = {
    str : "hello",
    arr : ["1", "2", "3", 4],
b : true,
    vobj : {
        str : "hello2"
    }
}

var ForReading = 1, ForWriting = 2;
var fso = new ActiveXObject("Scripting.FileSystemObject")
f1 = fso.OpenTextFile("your_object1.txt", ForWriting, true)
f1.Write(getAsText(obj, "\t"));
f1.Close();

f2 = fso.OpenTextFile("your_object2.txt", ForWriting, true)
f2.Write(getAsText(obj, "\t", true));
f2.Close();

your_object1.txt:

{ 
    "str" : "hello" ,
    "arr" : [ 
        "1" ,
        "2" ,
        "3" ,
        4
    ],
    "b" : true,
    "vobj" : { 
        "str" : "hello2" 
    }

}

your_object2.txt:

{ /* typeobj: object*/
    "str" : "hello" /* typeobj: string*/,
    "arr" : [ /* typeobj: object*/
        "1" /* typeobj: string*/,
        "2" /* typeobj: string*/,
        "3" /* typeobj: string*/,
        4/* typeobj: number*/
    ],
    "b" : true/* typeobj: boolean*/,
    "vobj" : { /* typeobj: object*/
        "str" : "hello2" /* typeobj: string*/
    }

}

在你知道对象只是一个布尔值的情况下，日期，字符串，数字等…javascript的String()函数工作得很好。我最近发现这在处理来自jquery的$的值时很有用。每个函数。

例如，下面将“value”中的所有项转换为字符串:

$.each(this, function (name, value) {
  alert(String(value));
});

详情如下:

看看jQuery-JSON插件

它的核心是使用JSON。但是如果浏览器没有实现它，它就会退回到自己的解析器。

我希望这个例子将有助于所有那些谁都在数组对象的工作

var data_array = [{
                    "id": "0",
                    "store": "ABC"
                },{
                    "id":"1",
                    "store":"XYZ"
                }];
console.log(String(data_array[1]["id"]+data_array[1]["store"]));

如果你不播放join()到对象。

const obj = {one:1, two:2, three:3};
let arr = [];
for(let p in obj)
    arr.push(obj[p]);
const str = arr.join(',');
