I have a json file and I wanted to display data from that file to HTML. I have written code but while coding it is giving error as 'Type Error: Failed To Fetch'
 
Here is the code of various files
 
JSON File
  1. [    
  2.     {    
  3.         "id": "1",    
  4.         "firstName": "John",    
  5.         "lastName": "Doe"    
  6.     },    
  7.     {    
  8.         "id": "2",    
  9.         "firstName": "Mary",    
  10.         "lastName": "Peterson"    
  11.     },    
  12.     {    
  13.         "id": "3",    
  14.         "firstName": "George",    
  15.         "lastName": "Hansen"    
  16.     }    
  17. ]  
  1. fetch('DisplayData.json')    
  2.     .then(function (response) {    
  3.         alert('Inside Fetch');    
  4.         return response.json();    
  5.     })    
  6.     .then(function (data) {    
  7.         appendData(data);    
  8.     })    
  9.     .catch(function (err) {    
  10.         alert('Error Occured' + err);    
  11.     });    
  12.     
  13. function appendData(data) {    
  14.     alert('Inside function');    
  15.     var m = document.getElementById("mDiv");    
  16.     for (var i = 0; i < data.length; i++) {    
  17.         var div = document.createElement("div");    
  18.         div.innerHTML = 'Name: ' + data[i].firstName + ' ' + data[i].lastName;    
  19.         m.appendChild(div);    
  20.     }    
  21. }
