copied!<p>There's no standard <code>show_my_div</code> function in PHP or JavaScript. You'd have to post the content of that function for anyone to help you with it.</p> <p>Outputting a div is easy in PHP:</p> <pre><code>echo "<div>content</div>"; </code></pre> <p>Similarly, it's easy in JavaScript to create a div element and append it to something. Here's raw JavaScript to append a div to the end of the page:</p> <pre><code>var div = document.createElement('div'); div.innerHTML = "The content of the div"; document.body.appendChild(div); </code></pre> <p>You can append elements anywhere, not just at the end. For instance, suppose I have a div with the id <code>foo</code>:</p> <pre><code><div id="foo"></div> </code></pre> <p>...and I want to add a paragraph to the end of it:</p> <pre><code>var p, div; div = document.getElementById('foo'); if (div) { // (Just being defensive) p = document.createElement('p'); p.innerHTML = "The text of the paragraph"; div.appendChild(p); } </code></pre> <p>These things are made easier if you use a JavaScript library like <a href="http://prototypejs.org" rel="nofollow noreferrer">Prototype</a>, <a href="http://jquery.com" rel="nofollow noreferrer">jQuery</a>, <a href="http://code.google.com/closure/library" rel="nofollow noreferrer">Closure</a>, or <a href="http://en.wikipedia.org/wiki/List_of_JavaScript_libraries" rel="nofollow noreferrer">any of several others</a> to smooth out browser differences and give you some syntactic sugar.</p>
