How to read an external local JSON file in JavaScript?

Question

I have saved a JSON file in my local system and created a JavaScript file in order to read the JSON file and print data out. Here is the JSON file:

{"resource":"A","literals":["B","C","D"]}

Let’s say this is the path of the JSON file: /Users/Documents/workspace/test.json.

Could anyone please help me write a simple piece of code to read the JSON file and print the data in JavaScript?

Answer 1

For reading the external Local JSON file (data.json) using javascript, first create your data.json file:

data = '[{"name" : "Ashwin", "age" : "20"},{"name" : "Abhinandan", "age" : "20"}]';

1. Mention the path of the json file in the script source along with the javascript file.

   <script type="text/javascript" src="data.json"></script>
   <script type="text/javascript" src="javascrip.js"></script>
   

2. Get the Object from the json file

   var mydata = JSON.parse(data);
   alert(mydata[0].name);
   alert(mydata[0].age);
   alert(mydata[1].name);
   alert(mydata[1].age);
