次の例は、jQuery Mobileフレームワークでの_iframe video_の使用を示しています。

$( document ).on( "pagecreate", function() {
function scale( width, height, padding, border ) {
var scrWidth = $( window ).width() - 30,
scrHeight = $( window ).height() - 30,
ifrPadding = 2 *padding,
ifrBorder = 2* border,
ifrWidth = width + ifrPadding + ifrBorder,
ifrHeight = height + ifrPadding + ifrBorder,
h, w;
if ( ifrWidth < scrWidth && ifrHeight < scrHeight ) {
w = ifrWidth;
h = ifrHeight;
} else if ( ( ifrWidth/scrWidth ) > ( ifrHeight/scrHeight ) ) {
w = scrWidth;
h = ( scrWidth/ifrWidth ) *ifrHeight;
} else {

w = ( scrHeight/ifrHeight )* ifrWidth;
}
return {
'width': w - ( ifrPadding + ifrBorder ),
'height': h - ( ifrPadding + ifrBorder )
};
};
$( ".ui-popup iframe" )
.attr( "width", 0 )
.attr( "height", "auto" );
$( "#popup_video" ).on({
