Question

我正在尝试为用户提供一个网站，以键入有关他们自己的信息，并最终生成供他们下载的Json文件。我可以使用Java来创建它，但是我需要一些帮助，将其变成网站供用户使用。

此外，如果有什么办法，我可以仅使用JS，HTML和CSS来做到这一点。

import java.io.FileWriter;
import java.io.IOException;
import java.util.Scanner;
import org.json.simple.*;

public class JsonFile {
    @SuppressWarnings("unchecked")
    public static void main(String[] args) {

        @SuppressWarnings("resource")
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter ID: ");
        int id_Input = scan.nextInt();
        System.out.println("Enter First Name: ");
        String firstname_Input = scan.next();
        System.out.println("Enter Last Name: ");
        String lastname_Input = scan.next();

        JSONObject patient = new JSONObject();
        patient.put("id", id_Input);
        patient.put("firstName", firstname_Input);
        patient.put("lastName", lastname_Input);

        System.out.println("Enter Father's First Name: ");
        String firstname_father = scan.next();
        System.out.println("Enter Father's Last Name: ");
        String lastname_father = scan.next();

        JSONObject father = new JSONObject();
        father.put("firstName", firstname_father);
        father.put("lastName", lastname_father);

        JSONArray list = new JSONArray();
        list.add(patient);
        list.add(father);

        try(FileWriter file = new FileWriter("testJSON.json")) {
            file.write(list.toString());
            file.flush();
        }
       catch(IOException e) {
            e.printStackTrace();
       }
    }
}

根据我的理解，您需要根据用户输入来转换JSON。使用下面的示例代码。可能会对您有帮助。

   <html>
<input type="text" id="txtid" value="Enter id"/>
<input type="text" id="txtfirstname" value="Enter first name"/>
<input type="text" id="txtlastname" value="Enter last name"/>
<input type="button" value="Display" id="btnDisplay" onclick="output()"/>

    <script>
        function output(){
            //Data collector
            var oData=[];
            //Local Data object initialization 
            var local={
                id:document.getElementById("txtid").value,
                firstname:document.getElementById("txtfirstname").value,
                lastname:document.getElementById("txtlastname").value
            };
            //Push data in data collector
            oData.push(local);
            //Convert data in json format string
            var output=JSON.stringify(oData).toString();
            //Data output
           document.write("<h1>"+ output +"</h1>")

           download("testfile.txt",output)
        }

        function download(filename, text) {
            var element = document.createElement('a');
            element.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text));
            element.setAttribute('download', filename);
            element.style.display = 'none';
            document.body.appendChild(element);
            element.click();
            document.body.removeChild(element);
        }

    </script>
</html>

//**Paste this code in HTML file and run**.
