Hi Larry, Great fan of you books! I've recently gone over Chapter 11 and I had a question regarding passing data from JSON to PHP using the code provided in the book for test.js (434-436). I've modified the script to use JSON and that works beautifully. I'd like to know if there is a clean JS solution to pass data to PHP without relying on jQuery.ajax({ data })? I've looked everywhere for a solution but the solution seems easily resolved with jQuery, but I'd like to avoid that if possible. Here is the code I've used as dictated in the book:
window.onload = function() {
'use strict';
var ajax = getXMLHttpRequestObject();
ajax.onreadystatechange = function() {
if ( ajax.readyState == 4 ) {
if ( (ajax.status >= 200 && ajax.status < 300) || (ajax.status == 304) ) {
var data = JSON.parse(ajax.responseText);
var file = '';
file += 'Original: ' + data['org'].file + '<br>';
file += 'Processed: ' + data['pre'].file + '<br>';
document.getElementById('output').innerHTML = file;
} else {
document.getElementById('output').innerHTML = 'Error: ' + ajax.statusText;
}
}
};
document.getElementById('btn').onclick = function() {
ajax.open('POST', 'resources/test.json', true);
ajax.setRequestHeader('Content-Type', 'application/json');
ajax.send(null);
};
};
I would like to be able to echo out the data['org'].file and data['pre'].file in PHP after the request is made. Any guidance or suggesting would be appreciated.
