[iOS][Safari] Avoid :focus zooming #2

hack-no-zooming.js

var $viewportMeta = $('meta[name="viewport"]');
$('input, select, textarea').bind('focus blur', function(event) {
    $viewportMeta.attr('content', 'width=device-width,initial-scale=1,maximum-scale=' + (event.type == 'blur' ? 10 : 1));
});

//The browser starts zooming in but immediately zooms out again when the elements gets focus. I like that.
