I've got a script executing on $(document).ready() that's supposed to vertically align block element in my layout. 90% of the time, it works without issue. However, for that extra 10% one of two things happens:
There's an obvious lag in the time it takes to do the centering, and the block elements jump into position. This could simply be performance related - as the page size is often large and there is a fair amount of javascript that is executing at once.
The centering will completely mess up, and the block element will either pushed down too far or not far enough. It appears as if it tried to calculate the height, but was getting improper measurements.
Is there any reason why executing a script on DOM-ready would not have all the correct CSS values injected into the DOM yet? (all CSS is in the <head>
via a <link>
).
Also, here's the script that's causing the issue (yes, it's been taken straight from here):
(function ($) {
// VERTICALLY ALIGN FUNCTION
$.fn.vAlign = function() {
return this.each(function(i) {
var ah = $(this).height();
var ph = $(this).parent().height();
var mh = (ph - ah) / 2;
$(this).css('margin-top', mh);
});
};
})(jQuery);
Thanks.
