How To Specifying Elements in a Hierarchy

In Hierarchy, JQuery, Plugin, Website Tutorial, Wordpress Tutorial on July 27, 2012 at 9:40 am

As the before topic says that jQuery is great at letting us select a set of elements. But what if you want to select one set in a page, but not another?
Say you have some

ele

ments in a

element that you want to select, but you don’t want to select any

<p> elements outside the <div> element.

One way of selecting the <p> elements we want is by specifying a selector hierarchy. For example, we can ask jQuery to select only those <p> elements that appear inside a <div> element, which itself appears in a <body> element, like this:

$(‘body div p’)

This tutorial will help us to make the selection that we want, and it will also let us change the style class of the selected elements when the user clicks a button, using the following code:

$(‘body divp’).toggleClass(‘striped’);

Steps to Select Elements in a Hierarchy are :

enter the code to add the jQuery library and add four <p> elements in a <div> element and one outside the <div> element, so total five <p> elements.

 

<html>
<head>

<title>Selecting elements in a hierarchy</title>

<script type=”text/javascript”src=”jquery-1.5.1.js”>
</script>

</head>
<body>

<h1>Selecting elements in a hierarchy</h1>

<div>
<p>This is paragraph 1.</p>

<p>This is paragraph 2.</p>

<p>This is paragraph 3.</p>

<p>This is paragraph 4.</p>

</div>

<p>This is paragraph 5.</p>

</body>
</html> Read the rest of this entry »

References to HTML elements from a script

References to HTML elements from a script

Each scripting language has its own conventions for referring to HTML objects from within a script. This specification does not define a standard mechanism for referring to HTML objects.

However, scripts should refer to an element according to its assigned name. Scripting engines should observe the following precedence rules when identifying an element: a

name

attribute takes precedence over an

id

if both are set. Otherwise, one or the other may be used.

18.2.3 Intrinsic events

Note. Authors of HTML documents are advised that changes are likely to occur in the realm of intrinsic events (e.g., how scripts are bound to events). Research in this realm is carried on by members of the W3C Document Object Model Working Group (see the W3C Web Site at http://www.w3.org/ for more information).
