in Default4 page i have a label with id Label1 when i click on close button i get undefined alert message

getElementById("Label1").text

An HTMLLabelElement doesn't have a text property.

If it's a simple label that contains only a single Text node, you can say:

getElementById('Label1').firstChild.data

If it might contain more complicated text and element nodes, you'd have to iterate over them to pick up the text, or use the DOM Level 3 Core textContent property, with backup for IE which doesn't support it:

var label= frames['frame1'].document.getElementById('Label1');
var text= ('textContent' in label)? label.textContent : label.innerText;

try with:

function Hidee() {
var ifr=document.getElementById("frame1"),
cd=ifr.contentDocument || ifr.contentWindow.document;
alert(cd.getElementById("Label1").innerHTML);
}
