function parseXml(xml) {
 //find every Tutorial and print the author
 $(xml).find("Tutorial").each(function()
 {
 $("#output").append($(this).attr("author") + "");
 });
}

$('#theGBin1Image').attr('src', 'image.jpg').load(function() {
alert('This Image Has Been Loaded');
});

//Events can be namespaced like this
$('input').bind('blur.validation', function(e){
 // ...
});
//The data method also accept namespaces
$('input').data('validation.isValid', true);

var dt = new Date();
dt.setSeconds(dt.getSeconds() + 60);
document.cookie = "cookietest=1; expires=" + dt.toGMTString();
var cookiesEnabled = document.cookie.indexOf("cookietest=") != -1;
if(!cookiesEnabled)
{
 //cookies have not been enabled
}

var date = new Date();
date.setTime(date.getTime() + (x * 60 * 1000));
$.cookie('example', 'foo', { expires: date });

$.fn.replaceUrl = function() {
  var regexp = /((ftp|http|https)://(w+:{0,1}w*@)?(S+)(:[0-9]+)?(/|/([w#!:.?+=&%@!-/]))?)/gi;
  this.each(function() {
   $(this).html(
    $(this).html().replace(regexp,'<A href="$1">$1</A>')
   );
  });
  return $(this);
 }
//usage
$('#GBin1div').replaceUrl();

大家可能在表单的操作中需要防止用户意外的提交表单，那么下面这段代码肯定非常有帮助：

$("#form").keypress(function(e) {
 if (e.which == 13) {
 return false;
 }
});

可能针对不同的表单形式，你需要调用不同类型的清楚方法，不过使用下面这个现成方法，绝对能让你省不少功夫。

function clearForm(form) {
 // iterate over all of the inputs for the form
 // element that was passed in
 $(':input', form).each(function() {
 var type = this.type;
 var tag = this.tagName.toLowerCase(); // normalize case
 // it's ok to reset the value attr of text inputs,
 // password inputs, and textareas
 if (type == 'text' || type == 'password' || tag == 'textarea')
