function createButton(context, func) {
    var button = document.createElement("input");
    button.type = "button";
    button.value = "im a button";
    button.onclick = func;
    context.appendChild(button);
}

window.onload = function() {
    createButton(document.body, function() {
        highlight(this.parentNode.childNodes[1]);
        // Example of different context, copied function etc
        // createButton(this.parentNode, this.onclick);
    });
};

Is that what you want?

I'm trying to use javascript to create a button that has a onclick event that calls a function defined in the head that takes in as parameter a dom object relative to the button. how do i do this?

ex:
```
<html>
<head> <script>function blah(obj){alert(obj.value)}</script></head>
<body>
<button onclick="blah(this.parentNode.value);"></button>
</body>
</html>
```
javascript:
```
var newButton = document.createElement("button");
???
```
in the end i want the new button to be the same as the existing one.
