    copied!<p>I'm trying to call a method <code>cardSelection()</code> from a <code>function game()</code> but instead I'm getting an error report which throws back to me the whole function with a "has no method cardSelection()" The idea is to access the method through the click of a button, which HTML tag is as follows:</p> <pre><code>&lt;img id="PlayerCard0" class="card" src="images/Cards/Mario.png" alt="Mario" title="Mario" onclick="game.cardSelection('PlayerCard0')"&gt; </code></pre> <p>I'm not posting the whole Javascript as I believe this to be the case of a mere declaration error, anyhow, <code>game()</code> and <code>cardSelection()</code> were declared as follows:</p> <pre><code>function game() { ... this.cardSelection = function(card) { var cardElem = document.getElementById(card); var id = cardElem.getAttribute("id"); var call = document.getElementById("call"); var select = function(card) { var found = 0; for (var card = 0, totalCards = 5; card &lt; totalCards; card++) { if (document.getElementById("PlayerCard" + card + "selected")) {found++} } if (found == 0) { call.setAttribute("onclick", "changeHand()"); call.childNodes[0].nodeValue = "Change"; } if (found &lt; 3) { id += "selected" setAttributes(cardElem, { "id" : id, "style": "position: relative; top: 1em;", "onclick" : "cardSelection('" + id + "')" }); } else { return; } } var unselect = function (card) { cardElem.removeAttribute("style"); id = id.replace("selected",""); setAttributes(cardElem, { "id" : id, "onclick" : "cardSelection('" + id + "')" }); var cardNumber = 0; var found = false; while (cardNumber &lt; 5 &amp;&amp; !found) { if (document.getElementById("playerCard" + cardNumber + "selected")) {found = true;} cardNumber++; } if (!found) { call.setAttribute("onclick", "compareHands()"); call.childNodes[0].nodeValue = "Hold"; } } if (id.indexOf("selected") &gt;= 0){unselect(card);} else {select(card);} } ... } </code></pre> <p>How <code>game()</code> is called:</p> <pre><code>window.onload = function openingScreen() { var startGame = document.createElement("a"); startGame.setAttribute("onclick", "game()"); startGame.appendChild(document.createTextNode("Play")); window.table = document.getElementById("table"); table.appendChild(startGame); } </code></pre>
