JQuery.ready is too late: How do I apply CSS Values with JQuery before Rendering? -

-

i want able apply opacity elements make them invisible only if javascript enabled. don't want use display:none because want layout act if they're in dom, setting opacity 0 perfect.

i want able set initial value using javascript, using jquery, don't have mess browser differences on opacity (and many other) attributes. if set opacity 0 so:

$(document).ready(function() {   $("#header").css("opacity", 0);   $("#header").animate({opacity:1}, 500); });

...half time it's visible on screen, appears , disappears.

how set these css values using jquery before ever can render?

looking jquery solution don't have manually handle every browser implementation this:

#header {   -moz-opacity:.50;   filter:alpha(opacity=50);    opacity:.50; }

just set opacity 0 in css file itself. cover scriptless, add following head:

<noscript><style>#header { opacity: 1; }</style></noscript>

update: since that's not option, next option execute script directly after #header element.

<div id="header"></div> <script>$("#header").css("opacity", 0).animate({opacity:1}, 500);</script>

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
