I am trying to get in the alert window the values of my class kreis attributes, but instead getting the background:#00FF00 and height:20px, the alert windows doesn´t prints anything, and I don´t know why. Thanks for your help in advance! Hereby the code:
<style>
#kreis{
width:200px;
height: 200px;
border-radius:50%;
background:#00FF00;
top: 300px;
text-align:center;
display: inline-block;
cursor:pointer;
}
</style>
<div onclick="Ball()" id="kreis"></div>
<script>
function Ball() {
alert("Hola");
var style=document.getElementById("kreis").style;
alert(style);
alert(style.background);
var color=style.height;
alert(color);
</script>
