  1. Hi ! On of the tutorial pages https://www.w3schools.com/js/js_json_html.asp is missing code of php file. As I understand the code should be the same as on previous page of chapter, like: <?php $myObj->name = "John"; $myObj->age = 30; $myObj->city = "New York"; $myJSON = json_encode($myObj); echo $myJSON; ?> Sincerely, Alejandro.
  2. Attention: W3Schools.com forum members: The following ".json" data file is used in conjunction with an AJAX ( Asynchronous Javascript And XML ) file to print a Bible verse to my web page: {"book": "Deuteronomy", "chapter": "4", "verse": "<p><sup><b>20</b></sup>&#8202But the L<font size="2">ORD</font> has taken you and <sup><i>c</i></sup>&#8202brought you out of the iron furnace,<br> out of &#8201Egypt, <sup><i>d</i></sup>&#8202to be a people of his own inheritance, as y
  3. I have 3 files: html that is displaying data from json file using AngularJS, json file containing the data, script.js that stores the scripts. HTML file also has a form, from which I want to add data to my json file (onsubmit="insertData()"). insertData function is going to be in script.js I know, I may use .push method for this, but I don't know how to apply to the json file in this case. script.js var prg = angular.module('ajsprogram', []); prg.controller("outercont", function($scope, $http) { //function to display json file information $http.get('airlines
  4. DILEMMA: I have a fairly complex JSON object that is introduced via an AJAX call. Unfortunately, my control panel tells me that it is undefined. Is this because it has no value? Or, is it because I do not know how to read the value properly? {"lastVisits"[{"firstVisit":{"prettyDate":"Monday, May 14, 2018"}}]} The name of the variable into which it is read is visitor_data. Am I reading the value of correctly? visitor_data.lastVisits[0].firstVisit.prettyDate Roddy
  5. I've built a static site with over 40,000 pages using Jekyll. I am trying to implement a live search into it without a database. I tried the w3schools live search example with a xml file I created from my site. It is very slow. Does anyone know of a faster way to parse xml files or am I wasting time. I enabled gzip compression on the entire site also, What would be the fastest way to search a lot of records and return a result? Thanks in advance.
  6. Hi, I've read the json tutorial on w3 website, and just have one question which makes a huge difference in the way I create the layout of my json file. All the examples they gave had a very short json file to read, but how does a json file look when you're trying to read many records. Does each httpRequest read the whole file from one first '{' to the last '}' and that's it. Or, if there are several, {'s will it return each one as an object. It was unclear to me from the tutorials. Specifically, If I had a database with 10 records and 5 fields in each, would I do this: { "name1" :

  15. Bootstrap sounds a bit like a finished optional program to use? also It seemed like when I first started seeing this page I have been learning from, that it is trying to "sell me" on the HTML5 as a good new and easier way to think of html code I wonder if this stuff has any merit? is it true? Is there any particular Web and computer code language *(scripting etc,) that are universal, or more functional for a different similar type? like for example I have read that someone wrote "there personal favorite scripting is" and similar quoted. Is there any that are not liked or favored by ma
