javascript - 在下一行(新行)中显示嵌套对象属性

Question

我有对象数组，其中有子对象(嵌套对象)。整个结构看起来与此类似(所有子对象都有相同的标签，只有值不同):

           var arr = [
                obj0 = {

                    subObj0: {
                        name: "John",
                        lastName: "Doe",
                        age: 50,
                        nick: "JD",
                        phone: 123456
                    },
                    subObj1: {
                        name: "Jane",
                        lastName: "Dee",
                        age: 30,
                        nick: "lady",
                        phone: 654098
                    },
                    subObj2: {
                        name: "Ash",
                        lastName: "Bash",
                        age: 33,
                        nick: "asdB",
                        phone: 987123
                    }
                },
                obj1 = {
                    subObj0: {
                        name: "Asd",
                        lastName: "Dsa",
                        age: 10,
                        nick: "none",
                        phone: 12
                    },
                    subObj1: {
                        name: "Ivy",
                        lastName: "Mash",
                        age: 3,
                        nick: "IvMash",
                        phone: 9823
                    }

                }

            ];

我试图在控制台中显示这些子对象，如下所示:

for (index in arr)
{
    for (index2 in arr[index])
    {
        console.log(JSON.stringify(arr[index][index2],null,4));
    }
}

，它为我提供了这些对象和子对象树的输出。

如何在控制台中显示它，因为每个子对象都在换行中，如下所示？

所以没有逗号和双引号，只有“label: value”形式。

很少有 replace() 可以做到这一点。单击运行按钮查看结果。

var arr = [
    {
        subObj0: {
            name: "John",
            lastName: "Doe",
            age: 50,
            nick: "JD",
            phone: 123456
        },
        subObj1: {
            name: "Jane",
            lastName: "Dee",
            age: 30,
            nick: "lady",
            phone: 654098
        },
        subObj2: {
            name: "Ash",
            lastName: "Bash",
            age: 33,
            nick: "asdB",
            phone: 987123
        }
    },
    {
        subObj0: {
            name: "Asd",
            lastName: "Dsa",
            age: 10,
            nick: "none",
            phone: 12
        },
        subObj1: {
            name: "Ivy",
            lastName: "Mash",
            age: 3,
            nick: "IvMash",
            phone: 9823
        }

    }

];

var output = [];
arr.forEach(function (obj, i) {
    output.push('obj' + i + ':');
    for (var key in obj) {
        var value = obj[key];
        var str = JSON.stringify(value)
            .replace(/[{}"]/g, '') // remove {} and "
            .replace(/[,]/g, '\t') // replace commas by tabulations
            .replace(/:/g, ': ');  // add a nice space after :
        output.push(key + ': ' + str);
    }
})

output = output.join('\n');
console.log(output);
document.write('<pre>' + output + '</pre>');
