Help with JSON and JavaScript...I have the other files but I only need help on this. Let me know if you want to see the rest.
1. Add code to the getContacts method that creates a function named reviver. Code the reviver method so it adds dashes back to regular phone numbers (7 characters), phone numbers with area codes (10 characters), and phone numbers with 1 + area code (11 characters). Then, use the reviver function with the parse method.
2. add code to the setContacts method that creates a function named replacer. Code the replacer function so it strips all non-numeric characters from the phone number value. Then, use the replacer function with the stringify method.
"use strict";
var storage = { keyContacts: "contacts_1", getContacts: function() { // get string from local storage var storageString = localStorage.getItem(this.keyContacts) || null; // convert string to JavaScript object and return, or return empty array if string is null return JSON.parse(storageString) || []; }, setContacts: function(value) { // convert JavaScript object to string var storageString = JSON.stringify(value); // store string in local storage localStorage.setItem(this.keyContacts, storageString); }, clearContacts: function() { localStorage.setItem(this.keyContacts, ""); } };
