We recommend 10 Great jQuery special effects codes and jquery special effects codes.
1. image pre-loading
(function($) { var cache = []; // Arguments are image paths relative to the current page. $.preLoadImages = function() { var args_len = arguments.length; for (var i = args_len; i--;) { var cacheImage = document.createElement('img'); cacheImage.src = arguments[i]; cache.push(cacheImage); } } jQuery.preLoadImages("image1.gif", "/path/to/image2.png");
2. Open the link in a new window (target = "blank ")
$('a[@rel$='external']').click(function(){ this.target = "_blank";}); /* Usage: <a href="http://www.catswhocode.com" rel="external">catswhocode.com</a>*/
3. Add class to the body when JavaScript is supported
/* This code has only one line, but it is the simplest method used to check whether the browser supports JavaScript. if JavaScript is supported, add a hasJS class to the body element */
$('body').addClass('hasJS');
4. Smoothly scroll the page to an anchor.
$(document).ready(function() { $("a.topLink").click(function() { $("html, body").animate({ scrollTop: $($(this).attr("href")).offset().top + "px" }, { duration: 500, easing: "swing" }); return false; });});
5. Fade-in and fade-out when the mouse slides
$(document).ready(function(){ $(".thumbs img").fadeTo("slow", 0.6); // This sets the opacity of the thumbs to fade down to 60% when the page loads $(".thumbs img").hover(function(){ $(this).fadeTo("slow", 1.0); // This should set the opacity to 100% on hover },function(){ $(this).fadeTo("slow", 0.6); // This should set the opacity back to 60% on mouseout });});
6. Create a column with a height
var max_height = 0;$("div.col").each(function(){ if ($(this).height() > max_height) { max_height = $(this).height(); }});$("div.col").height(max_height);
7. Enable HTML5 support in some old browsers
(function(){ if(!/*@cc_on!@*/0) return; var e = "abbr,article,aside,audio,bb,canvas,datagrid,datalist,details,dialog,eventsource,figure,footer,header,hgroup,mark,menu,meter,nav,output,progress,section,time,video".split(','),i=e.length;while(i--){document.createElement(e[i])}})()
// Then introduce the js in the head
<! -- [If lt IE 9]>
<Script src = "http://html5shim.googlecode.com/svn/trunk/html5.js"> </script>
<! [Endif] -->
8. test whether the browser supports certain CSS3 attributes.
var supports = (function() { var div = document.createElement('div'), vendors = 'Khtml Ms O Moz Webkit'.split(' '), len = vendors.length; return function(prop) { if ( prop in div.style ) return true; prop = prop.replace(/^[a-z]/, function(val) { return val.toUpperCase(); }); while(len--) { if ( vendors[len] + prop in div.style ) { // browser supports box-shadow. Do what you need. // Or use a bang (!) to test if the browser doesn't. return true; } } return false; };})(); if ( supports('textShadow') ) { document.documentElement.className += ' textShadow';
9. Get the parameters passed in the URL
$.urlParam = function(name){ var results = new RegExp('[\\?&]' + name + '=([^&#]*)').exec(window.location.href); if (!results) { return 0; } return results[1] || 0;}
10. Disable the form's enter key submission
$("#form").keypress(function(e) { if (e.which == 13) { return false; }});
