Question

I have following div with a textbox in it.

<div id="DvPrint">
    <div>
    <input type="text" style="width: 100px;
                                    margin-left: 25px;" class="textbox" id="ctl00_content_TxtLetterNumber" readonly="readonly" name="ctl00$content$TxtLetterNumber">
    </div>
    </div>

Now I write the div contents in a new window using window.open.

 n = window.open('M80Print.aspx', '_blank', 'status=no,toolbar=no,menubar=yes,height=550px,width=640px');
            n.document.open();
 n.document.write($('#DvPrint').html());

Now I want to change the textbox value in new opened window. How can I do it??
Something like this:

n.document.getElementById('ctl00_content_TxtLetterNumber').innerHTML = "1";

but it doesn’t work.

Answer 1

n.document.getElementById('ctl00_content_TxtLetterNumber').value = "1";

Changing textbox value is being done with value, not with innerHTML.

jQuery:

$('#ctl00_content_TxtLetterNumber', n.document).val('1');
