Is this code correct for applying curvy corners to several items?

window.onload = function() {
var settings = {
tl: { radius: 20 },
tr: { radius: 20 },
bl: { radius: 20 },
br: { radius: 20 },
antiAlias: true
}

var divObj = document.getElementById("myDiv");
curvyCorners(settings, ".zone-content");

var divObj = document.getElementById("myDiv");
curvyCorners(settings, ".group-right");

}
