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"]));

我建议使用JSON。stringify，它将对象中的变量集转换为JSON字符串。

var obj = {
  name: 'myObj'
};

JSON.stringify(obj);

大多数现代浏览器都支持这种方法，但对于那些不支持的浏览器，您可以包含一个JS版本。

以你为例，我想 console.log(“项目:”,o) 这是最简单的。但是, console.log("Item:" + o.toString) 也会起作用。

使用方法一可以在控制台中使用一个漂亮的下拉菜单，因此长对象可以很好地工作。

var obj={
name:'xyz',
Address:'123, Somestreet'
 }
var convertedString=JSON.stringify(obj) 
 console.log("literal object is",obj ,typeof obj);
 console.log("converted string :",convertedString);
 console.log(" convertedString type:",typeof convertedString);

/*
    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 + "\" ";
        res += (show_types == true) ? "/* typeobj: " + typeof(obj) + "*/" : "";
    } else if (typeof(obj) == "number" || typeof(obj) == "boolean") {
        res += obj;
        res += (show_types == true) ? "/* typeobj: " + typeof(obj) + "*/" : "";

        res += show_types ? "/* typeobj: " + typeof(obj) + "*/" : "";
        res += "\r\n";
        var new_ident = ident + inc_ident;
        var arr = [];
        for(var key in obj) {
            arr.push(new_ident + getAsText(obj[key], inc_ident, show_types, new_ident));
        } 
        res += arr.join(",\r\n") + "\r\n";
        res += ident + "]";
    } else {
        var new_ident = ident + inc_ident;      
        res += "{ ";
        res += (show_types == true) ? "/* typeobj: " + typeof(obj) + "*/" : "";

            arr.push(new_ident + '"' + key + "\" : " + getAsText(obj[key], inc_ident, show_types, new_ident));
        }
        res += arr.join(",\r\n") + "\r\n";
        res += ident + "}\r\n";

    return res;

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*/
    }
