onclick event in the javascript

javascript

Solution

<input id="myElement" type="button" value="Click me!" />
<script type="text/javascript">
    document.getElementById('myElement').onclick = function () {
        alert('Hello, world!');
    }
</script>

Make sure that you either run this after the element already exists (scripts at the bottom), or when the DOM is ready. (You could use `window.onload` for that, but you might just want to use jQuery from the beginning so that, among other things, you get a magical DOM-ready function. `onload` has some downsides, like waiting for images to load.)

Problem

I am very new to javascript I know that you can add an onclick="" event to a html element... but is it possible in the javascript itself to declare that when someone clicks on x element an event is triggered?
