What is jQuery Plugin?

We can package our re-usable jQuery code. This package will require jQuery core as base to run. So we refer these packaged jQuery code as Plugins. There are many thousands famous free plugins over the internet.

Have you ever used any Plugin?

Yes, I have used tablesorter, jAlert. (here you can name what you have used/known)

Which selector you prefer, ID based or class based and why?

I prefer using efficient selector and prefer ID based if possible. Class based selector can yield me object array while ID based will give the exact one.

What is default context if we not supply?

Default context is the DOM/ Document.

The syntax is $( selector , context ) and if we omit context, Document is consider as the context.

How can we load an aspx page inside a DIV element on other aspx page?

$.load( url_of_aspx_page);

What is difference between width() and outerWidth() ?

width() gives the only content-area's width while outerWidth() gives the actual content-area width plus area occupied by border and padding Refer : http://www.c-sharpcorner.com/UploadFile/bc1c71/display-message-box-in-center-of-window-using-jquery/

What is jQuery event bubbling?

What is jQuery event Propagation?

When an event is fired on a child element, it get propagate to its parents for handling the same. This is known as event bubbling. jQuery support this. We can stop event Propagation by –

a) checking the actual target ex. e.target == this

b) using e.stopPropagation();

Is there any difference between window.onload event & $(document),ready event?

jQuery has a ready event which automatically triggered when Document becomes ready(still images may be being loaded but DOM is ready for operations). So code written inside this ready event comes in action only after the document is ready. This DOM ready wait, ensures that referring element is able to access and avoid the null or undefined/non-existence problem. If we still want more wait until everything is fully loaded including banner-images then load event can be used instead of ready event. In native JavaScript, there is also a 'window.onload' event which happen when document is fully loaded including banner images etc.
