  1. Is w3c a truce source to follow for any errors found on a website? For eg. I have my links setup like this. < a href="record.php?id=4&user=smith"></a> W3C is tell me to not use "&" symbol and that instead escape it as & So what do I just replace & with & in all my links?
  2. Hello mates, I'm a newbie to JavaScript. Normally when I assign an HTML element to a variable created in JavaScript I place the element id in quotes like this: var output = document.getElementById('output'); But there is something new that I've come across: var output = document.getElementById(elementId); elementId is an undeclared parameter and it is without quotes. 'output' in the first snippet refers to <p id="output"></p> in the HTML code. What is surprising to me is that var output = document.getElementById(elementId); works just the same even though there is no HTML element declared with the name elementId. To put this into context, the code is in 2 files; today.html and today.js. today.html: <html> <head> <title>Today</title> </head> <body> <p id="output"></p> <script src="today.js"></script> </body> </html> today.js: function setText(elementId, message) { 'use strict'; if ( (typeof elementId == 'string') && (typeof message == 'string') ) { // Get a reference to the paragraph: var output = document.getElementById(elementId); // Update the innerText or textContent property of the paragraph: if (output.textContent !== undefined) { output.textContent = message; } else { output.innerText = message; } } // End of main IF. } function init() { 'use strict'; var today = new Date(); var message = 'Right now it is ' + today.toLocaleDateString(); message += ' at ' + today.getHours() + ':' + today.getMinutes(); // Update the page: setText('output', message); } // End of init() function. window.onload = init;
