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>

How to Creating New HTML Elements

In HTML Element, JQuery, Srcipt PHP, Tutorial, Website Tutorial, Wordpress Tutorial on July 27, 2012 at 9:13 am

jQuery help us to create an HTML elements and insert them into a page.

If we pass a text string that spells out a new HTML element to the jquery ( ) or $( ) function (which are the same thing), jQuery will create that new element:

$(“<p>I’m a new &lt;p&gt;element!</p>”)

The upper code will display ”  I’m a new <p> element ! “

To actually get the new element into a page, we have to use a function like insert After () , passing a selector indicating the element that you want to insert the new element after.

This tutorial creates new <p> elements and inserts them into a page following a <p> element with the ID “first”, like this:

$(“

I’m a new <p>element!

”).insertAfter(“#first”);

To create new elements:

1. We are going to use text editor (such as notepad or Wordpad) to create our HTML page and give the file name as “create.html”.

2. Enter the code to add the jQuery libraryand add a element with the ID “first”. Read the rest of this entry »
