Smart Text Re sizer ala jQuery（和cookies）

Posted 2021-02-26

You'll need the latest version of [jQuery](http://www.jquery.com) and the jquery.cookie plugin([Snag it here!](http://www.stilbuero.de/2006/09/17/cookie-plugin-for-jquery/))

<script src="graphics/js/jquery-1.2.6.min.js" type="text/javascript"></script>
<script src="graphics/js/jquery.cookie.js" type="text/javascript"></script>
<script type="text/javascript" charset="utf-8">
	$(document).ready(function() {
		// See which font size the user wants
		$(".text a").click(function() {
			switch ($(this).attr("class")) {
				case 'small'	: setFontSize(.8);	break;
				case 'large'	: setFontSize(1.6);	break;
				case 'default'	: setFontSize(1.2);	break;
			}
			return false;
		});
 
		// Set the font size and set a cookie
		function setFontSize(size) {
	        $("#wrap, input, textarea").animate({fontSize: size+"em"}, 500).fadeIn("slow");
				createCookie(size);
			}
 
			// Create and read coookies
			// Code functions by: Peter-Paul Koch
			// http://www.quirksmode.org/js/cookies.html
			function createCookie(value) {
				var date = new Date();
				date.setTime(date.getTime()+(30*24*60*60*1000));
				var expires = "; expires="+date.toGMTString();
				document.cookie = "font_size="+value+expires+"; path=/";
			}
		var font_size = $.cookie('font_size');
		   if (font_size == '0.8') {
		        $('#wrap').css("font-size",".8em");
			}
		   if (font_size == '1.6') {
		        $('#wrap').css("font-size","1.6em");
			}
		   if (font_size == '1.2') {
		        $('#wrap').css("font-size","1.2em");
			}
	});
</script>
