Re-positioning div/ moving div to left and right with JavaScript
<p>I am new to javascript and I am trying to start a very simple project which is to display a controllable div that can be moved around using a,w,s,d keys on keyboard. I am currently having problem on how to move around the div because I do not know what attribute to change.</p>

<pre><code>divBar = null;

function detectKey() {
    //97 = a
    //115 = s
    //100 = d
    //119 = w

    if (event.charCode == 97) {
       //a
       alert(divBar.position);
    }
    if (event.charCode == 115) {
        //s
    }
    if (event.charCode == 100) {
        //d
    }
    if (event.charCode == 119) {
        //w
    }
}

function createDiv() {
    divBar = document.createElement("div");
    divBar.id = "divBar";
    divBar.style.border = "solid 1px #AAAAAA";
    divBar.style.backgroundColor = "black";
    divBar.style.top = 400;
    divBar.style.height = "10px";
    divBar.style.width = "100px";
    divBar.style.position = "absolute";
    document.body.appendChild(divBar);
    document.addEventListener("keypress", detectKey, false);

}
</code></pre>

<p>I am not sure to put in that condition statement. so that the div will move to the left, right, up and down.</p>
