}

content += "<input type='button' name='goto' onclick='popup1()' value='Check'></form>";

if (ie7 == false) {
    newsletterall[0].childNodes[1].innerHTML = content;
} else {
    newsletterall[0].childNodes[0].innerHTML = content;
}

I have created the checkbox.Now I need to create a popup window at the middle and get the values of the checkbox and to display it.

To access the object of the parent window, there is a property on the child (e.g. popup) window object called opener.

var parentWindow = window.opener;

Using that object you should be able to access the parent window’s form.

var value = parentWindow.document.getElementById("compare").value;
