Printing contents of a dynamically created iframe from parent window

jquery iframe printing

Suppose that this is what your iframe looks like:

<iframe id='print-iframe' name='print-frame-name'></iframe>

This is how you do it using jQuery:

$("#print-iframe").get(0).contentWindow.print();

and this is how you do it using native JavaScript:

document.getElementById("print-iframe").contentWindow.print();

I tried this and was able to replicate the issue. What i noticed was that when calling the print function the iframe hadn't completed loaded. i tested this by checking the value of innerHTML when calling PrintIFrame(). To overcome this, you can use setTimeOut to call the function again x milliseconds later:

function PrintIframe() { 

        if (window.frames['myname'].innerHTML != "") {
            window.frames['myname'].focus();
            window.frames['myname'].print();
        } else {
            setTimeout(PrintIframe,1000);
        }    
    }

This worked for me

EDIT Strange - i had an alert in my test code which seems to make it work. When i took it out, it didn't work. Sorry :(

Anyway, this should do it using jQuery to attach a load event handler to the iframe. I have tested on IE8 and it works:

<html>
<head>
    <script language="javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
    <script type="text/javascript">
    function loadiFrame(src)
    {
        $("#iframeplaceholder").html("<iframe id='myiframe' name='myname' src='" + src + "' />");
    }

    $(function()
    {
        $("#printbutton").bind("click", 
            function() { 
                loadiFrame('test.aspx'); 
                $("#myiframe").load( 
                    function() {
                        window.frames['myname'].focus();
                        window.frames['myname'].print();
                    }
                 );
            }
        );
    });
    </script>    
</head>
<body>
    <input type="button" id="printbutton" value="Load iFrame" />
    <div id="iframeplaceholder"></div>
</body>
</html>

I've had an issue with printing iframe's content. In order to achive this, use code below:

For example you have iframe:

<iframe id='print-iframe' name='print-iframe'></iframe>

Then js to print iframe's content call this function (works both in ie and other browsers):

printIframe('print-iframe');

Function's code:

function printIframe(iFrameId) {
    var ua = window.navigator.userAgent;
    var msie = ua.indexOf ("MSIE ");
    var iframe = document.getElementById(printFrameId);

    if (msie !== 0) {
        iframe.contentWindow.document.execCommand('print', false, null);
    } else {
        iframe.contentWindow.print();
    }
}

I have a page with a list of links and a div which serves as a placeholder for the pages the links lead to. Everytime user clicks on a link an iframe is created in the div and its src attribute gets the value of the link href attribute - simple and clear, sort of external web pages gallery. What i do have a problem with is printing the contents of the iframe. To do this i use this code:
```
function PrintIframe()  
{  
frames["name"].focus();  
frames["name"].print();  
}
```
The issue seems to be that iframe is created dynamically by JQuery - when I insert an iframe right into the html code, the browser prints the external page all right. But with the same code injected by JavaScript nothing happens. I tried to use JQ 1.3 'live' event on "Print" link, no success. Is there a way to overcome this?
