Discover how to efficiently load and display a JSON array or object using JavaScript

I am new to learning about json and d3, having just started a few hours ago. While I have basic knowledge of javascript, I need help with loading a json file and displaying all the arrays and objects on the console using d3. I tried to do it myself but unfortunately, my solution did not work :( Here is a snippet of my json file.

 {
    "addressfile": "info", 
        "struct": {
          "address": [
               [
                  "A", 
                  "B", 
               ], 
               [
                  "B", 
                  "C", 
               ], 
         ], 

           "address1": {
           "address2": {
           "address3": {
                  "zip": [
                      "NUMBER", 
                        0
                     ]
                  }, 
            "address_type": "Home"
            }, 
         }
     }, 
    "COUNTRY": {}, 
    }

This is my current javascript code...

<!DOCTYPE html>
<meta charset="utf-8">
<style>
<body>
<script>
//LOADING JSON FILE
d3.json("address.json", function(error, root) {
      if (error) return console.error(error);
          for (var p in location) if (location.hasOwnProperty(p)) {
               console.log(p + " : " + location[p]);
           }
       }
 </script>
 </body> 
 </html>

If anyone could assist me in solving this issue, I would greatly appreciate it!

javascript json object d3.js load

Answer 1

Answer №1

Give it a shot

d3.parse("details.json", function(info) {

Although the documentation states that the callback requires two arguments, my experience working on a previous project using d3 version 3.4.13 showed that the callback function only accepted the data parameter for it to function properly.

Your code is missing a closing parenthesis - );

Here is the corrected code:

<script>
    d3.json("appdata.json", function(error, data) {
         if (error) return console.error(error);

          console.log(data) // displays your JSON data as an object

          //for (var key in location) if (location.hasOwnProperty(key)) {
          //     console.log(key + " : " + location[key]);
          //}
    });
</script>

Ensure you provide the correct URL to your JSON file as the first parameter to d3.json().
Verify that appdata.json contains valid JSON data by using http://jsonlint.com/.

         if (error) return console.error(error);

          console.log(data) // displays your JSON data as an object

          //for (var key in location) if (location.hasOwnProperty(key)) {
          //     console.log(key + " : " + location[key]);
          //}
    });

Gratitude to all for the assistance.. I've successfully overcome the challenges faced and reached a resolution.. Resolution: The browsers do not support external Json files, hence a webserver was necessary. This allowed me to view the output in the console. Here is the final code snippet:

<!DOCTYPE html>
<meta charset="utf-8">
 <head>
   <script src="http://d3js.org/d3.v3.min.js"></script>
 </head>
 <body>
   <script>
        d3.json("address.json", function(location) {
        console.log(location)
  });
   </script>
 </body>
 </html>

Hoping that this solution can benefit others in resolving their issues swiftly, unlike the significant time it took me.....
