For a beginner in jQuery programming, you will probably find that the 3 methods based on HTML elements, IDs and classes mentioned in the earlier post will be sufficed.
For a more thorough treatment of jQuery selectors, you can refer to this guide.
Nonetheless, we will go ahead and list down some common selectors.
|$('*')||Selects all elements|
|$('#demo_id')||Selects elements with id='demo_id'|
|$('.demo_class')||Selects all elements with class='demo_class'|
|$('p')||All <p> elements|
|$('ul li:first')||This selector gets only the first <li> element of the <ul>|
|$('li:not(.myclass)')||Selects all elements matched by <li> that do not have class='myclass'.|
