What is Jquery

jQuery is a lightweight JavaScript library that emphasizes interaction between JavaScript and HTML. jQuery is an amazing JavaScript library that makes it easy to create wonderful web effects in just a few lines of code. jQuery is a new type of Javascript library. It is not a huge, bloated framework promising the best in AJAX – nor is it just a set of needlessly complex enhancements – jQuery is designed to change the way that you write Javascript.
jQuery is a Javascript library that takes this motto to heart: Writing Javascript code should be fun. jQuery achieves this goal by taking common, repetitive, tasks, stripping out all the unnecessary markup, and leaving them short, smart and understandable.
Quick Facts

• jQuery supports CSS 1-3 and basic XPath.
• jQuery is about 19kb in size.
• jQuery works in Firefox 1.0+, Internet Explorer 5.5+, Safari 1.3+, and Opera 8.5+.
• jQuery and Prototype can be used together!
• jQuery owns a strong and very flexible mechanism for adding in methods and functionality, bundled as plugins

jQuery contains the following features:

• DOM element selections using the cross-browser open source selector engine Sizzle, a spin-off out of jQuery project[3]
• DOM traversal and modification (including support for CSS 1-3 and basic XPath)
• Events
• CSS manipulation
• Effects and animations
• Ajax
• Extensibility
• Utilities – such as browser version and the each function.
• The $ function• One of the critical concepts in any jQuery code is the so called ‘$’ function. ‘$’ is actually an ‘alias’ for the ‘jQuery’ namespace.
• Example 1: jQuery provides a function for trimming strings. This function can be used as:

 
•	str = "    foo     ";
•	jQuery.trim(str); // returns "foo"
•	Or, it can also be used as:
•	str = "    foo     ";
•	$.trim(str);

• These are equivalent. Usage of ‘$’ instead of ‘jQuery’ is an ad-hoc convention, and is considered easier[who?].
• Example 2: To select all the paragraphs that have the class ‘foo’ and add another class called ‘bar’ to all of them:
• $(“p.foo”).addClass(“bar”);
• Example 3: To execute a function ‘myfunc’ immediately after the page is loaded (called the ready handler in jQuery lingo):
• $(document).ready(function() {
• myfunc();
• });
• This is typically used in a context like this:
• $(document).ready(function() {
• // Stripe all the tables in the document using the oddStripe and evenStripe CSS classes.
• $(‘tr:nth-child(odd)’).addClass(“oddStripe”);
• $(‘tr:nth-child(even)’).addClass(“evenStripe”);
• });

Refreshing the page by java mehtod in Oracle ADF

In Oracle ADF, for refreshing the page after doing some operation in database we need to refresh the Page ,which is very needed to display the right content.For this we need to write java method in page.java file. Write that method anywhere in java file and call that method anywhere where you want to refresh the page.

protected void refreshPage() {
      FacesContext fc = FacesContext.getCurrentInstance();
      String refreshpage = fc.getViewRoot().getViewId();
 ViewHandler ViewH =                                                                                                                   
 fc.getApplication().getViewHandler();
      UIViewRoot UIV = ViewH.createView(fc refreshpage);
      UIV.setViewId(refreshpage);
      fc.setViewRoot(UIV);
}

This is only method you need to write to refresh the page.
