Question

I have a SharePoint page that has a hyperlink which points to a video clip. Clicking on the link will play the video in an overlay window (uses Silverlight). If Silverlight runtime is not present, it displays the “install Silverlight” prompt. When the page is invoked with a IsDlg=1 query string, the hyperlink is hidden (it is in the left navigation bar), and only the main content page is shown. But I still get the “install Silverlight” prompt. I want to get rid of the prompt when IsDlg=1 is present.

Below is the relevant javascript code on the page. I’ve modified it slightly to initialize the media player only if IsDlg=1 is not present. But it is not working as expected. Any ideas?

// original code
 $(function () {
        mediaPlayer.createOverlayPlayer();
        mediaPlayer.attachToMediaLinks(document.getElementById('videoList'), ['wmv', 'avi', 'mp4']);
    });

// modified code
    $(function () {
        var field = 'IsDlg';
        var url = window.location.href;
        if (url.indexOf('?' + field + '=') != -1) {

        } else {
            mediaPlayer.createOverlayPlayer();
            mediaPlayer.attachToMediaLinks(document.getElementById('videoList'), ['wmv', 'avi', 'mp4']);
        }
    });

Answer 1

As long as the HTML which embeds the Silverlight control is present, it will show the “Install Silverlight” dialog. If you don’t want the dialog to show, you’ll have to change the HTML source. You could add JavaScript code to add the HTML dynamically, so that it only shows when necessary. That answer would depend on how you’re currently embedding the Silverlight control.

EDIT: You could try code like this:

$(function () {
    if (window.location.search.indexOf('IsDlg=1') === -1) {
        $.getScript('/_layouts/mediaplayer.js', function () {
            mediaPlayer.createOverlayPlayer();
            mediaPlayer.attachToMediaLinks(document.getElementById('videoList'), ['wmv', 'avi', 'mp4']);
        });
    }
});
