Question

我试图用javascript编辑我的json文件。我的json文件代码是

{
"contacts": {
    "contact": {
        "info": [
            {
                "id": "0",
                "name": "name",
                "number": "0",
                "email": "email"
            }
        ],
        "messages": [
            {
                "message": [
                    {
                        "-from": "0",
                        "-to": "0",
                        "info": {
                            "id": "0",
                            "name": "name",
                            "number": "0",
                            "email": "email"
                        },
                        "text": [
                            {
                                "subText": {
                                    "-italics": "false",
                                    "-underline": "false"
                                }
                            }
                        ],
                        "file": [
                            {
                                "-size": "0",
                                "-type": "image",
                                "fileInfo": {
                                    "id": "0",
                                    "name": "name",
                                    "number": "0",
                                    "email": "email"
                                }
                            }
                        ]
                    }
                ]
            }
        ]
    }
}
}

我想设置contacts.contact.info.id的值，我想在contacts.contact.info中添加另一个数组。 PLZ帮我解释语法。我在创建信息数组中创建新元素时遇到问题。并告诉如何显示contacts.contact.info元素的值

Answer 1

使用JavaScript，它非常简单：

var data = {};//your json string here
data.contacts.contact.info[0].id = 'New value here'; //id is in array
data.contacts.contact.info.push('Append this value to info');
//or
data.contacts.contact.info = 'Overwrite current info value';
//get string
console.log(JSON.stringify(data));

这就是全部。如果要手动更改数据：

{
"contacts": {
    "contact": {
        "info": [
            {
                "id": "0",//replace with, for example:
                "name": "name",
                "number": "0",
                "email": "email"
            },//add comma, and data below:
            {
                "id": "123",
                "name": "foobar",
                "number": "1"
            },
            "primitives go here, too"
        ],//end array
        "messages": [...

这就是它的全部内容按照您的要求保留漂亮的印刷：

var data = JSON.parse(yourString);
data.contacts.contact.info.push(
    {"id": "7","name": "dg","number": "5454","email": "fsfsf"}
);
data.contacts.contact.info.push(
    {"id": "8","name": "gjhhk","number": "64564","email": "fs54f"}
);
//get pretty string, using spaces for indentation:
console.log(JSON.stringify(data, null, ' '));
//same thing, but using tabs:
console.log(JSON.stringify(data, null, '\t'));

Answer 2

你可以试试这个：

var json={contacts:{contact:{info:[{id:"0",name:"name",number:"0",email:"email"}],messages:[{message:[{"-from":"0","-to":"0",info:{id:"0",name:"name",number:"0",email:"email"},text:[{subText:{"-italics":"false","-underline":"false"}}],file:[{"-size":"0","-type":"image",fileInfo:{id:"0",name:"name",number:"0",email:"email"}}]}]}]}}};

console.log(json.contacts.contact.info[0]); //access first record

json.contacts.contact.info.push({id:"1",name:"name",number:"1",email:"abc@xyz.com"}); // add new info

console.log(json.contacts.contact.info);

Answer 3

contacts.contact.info.id ：

contacts.contact.info是一个数组..所以你必须按索引工作：

contacts.contact.info[0].id = newID;

添加到此数组：

contacts.contact.info.push(newArrayItem);

希望这能回答你的问题..
