Simply i want to append some characters to the parent window's textarea.
str="some character"
window.opener.document.getElementById('id1').value = str;
It changes the parent window's textarea's value to "some character"..But I want to append this text to textarea's value. like,
window.opener.document.getElementById('id1').value.append(str); // not working
But it is not working.
How can I do this?
