your code is wrong, getElementsByTagName returns an array. this works:
private native void n1()/*-{
$wnd.alert(eval("document.getElementsByTagName('div')"));
}-*/;
I do not recommend to use eval. For accessing html DOM I recomment google dom
java api, for example in your case:
private void n2(String s1, String s2) {
NodeList<Element> els = Document.get().getElementsByTagName(s1);
for (int i = 0; i < els.getLength(); i++) {
Element d1 = els.getItem(i);
d1.getStyle().setBorderColor("red");
}
}
