Question

Is it possible to create a copy variable of document in javascript?

As I am a C# developer I want something like

var doc=new document();

    var doc = document;
    doc.open('application/txt', 'replace');
    doc.charset = 'utf-8';
    doc.write('Message to write in txt file');
    doc.close();
    if (doc.execCommand('SaveAs', true,'test.txt')) {
        alert(success);
    }

I have one button and some other controls in the iframe popup where i want to open saveas dialog onclick of button. After i run the above code ‘Message to write in txt file’ is showing in the page where i have my button and other controls

I have resolved this issue like below. I have added a iframe in my page and did the below.

    var iframe = document.getElementById('iframe');
    var doc = iframe.contentDocument;
    var message = 'Message to write in txt file';           
    doc.open('application/txt', 'replace');
    doc.charset = 'utf-8';
    doc.write(message);
    doc.close();

    doc.execCommand('SaveAs', true, 'test.txt');
