How can I display a full screen google map with jQuery Mobile?

Question

The following code displays strange output. I should see a full screen mobile map. But for some reason it shows on just a portion of the screen. I am using jquery.ui

I've been messing around with this for a bit, and managed to find the perfect solution. It caters for pages with or without a header. It will position the map perfectly in the space between the header and the bottom of the page (or on the whole page if a header is not present), for any resolution and any header height.

This solution requires both CSS and JS if the page has a header, and CSS only if the page does not have a header.

HTML

CSS

#map-canvas {
    position: absolute;
    width: 100%; 
    height: 100%;
    top: 0;
    left: 0;
}

/* eliminates scrollbars in map infowindow (optional) */
#mappopup {
    line-height: 1.35;
    overflow: hidden;
    white-space: nowrap;
}

JS

var mapPageHeader = $("#mapPage .ui-header").eq(0);
if(mapPageHeader.length > 0) {
    var headerHeight = mapPageHeader.outerHeight();
    $("#map-canvas").css({
        'height': ($(window).height() - headerHeight + 1) + 'px',
        'top': headerHeight - 1
    });
}
