Question
I have a page in which i m calling another popup by window.open method. The only thing how can i change a label in opener page from popup page while the popup page is still alive ie which is not closed yet
Solution
It should be like this:
window.opener.document.getElementById('label1').value = "the new value";
OTHER TIPS
It's better to let the opener window take care of changing values by exposing a small API to the popup window.
I've outlined it here: javascript - pass selected value from popup window to parent window input box
<script>
function myFunction() {
var additionalWindow = window.open("/additional");
// Write on the additional window
additionalWindow.document.write('written from separate window');
// Call a function on the additional window
additionalWindow.someFunction();
}
</script>
