In this lesson, we will explore jQuery selectors and jQuery effects.

Selectors

Among selectors, we will most often use classes and IDs. Selectors generally correspond to CSS selectors, so if you know how to write selectors in CSS, you already know how to write them in jQuery. Here's how we select classes:

$('.class')

And here's how we select IDs:

$('#id')

In this video, we will explore how to work with CSS using the capabilities of jQuery.

In this lesson, we will cover events in jQuery. We will also get acquainted with the animate() method, which allows us to create animations. Using events and animate(), we’ll build an animated contact form.

In this video, we’ll learn how to use jQuery to create an online calculator. We’ll also connect the Sexy Uniform plugin to make our buttons look stylish.

In this lesson, we’ll look at how to create a simple photo gallery using jQuery.

You've probably seen a search field with the word "Search" in it, which disappears when clicked so you can type your query. Below is a jQuery snippet for that functionality:

File code

/sites/all/modules/custom/custom.info

name = custom
description = custom module
core = 7.x

/sites/all/modules/custom/custom.module

CSS code:

#tabs {
  border: 0px;
}

.ui-tabs-nav {
  background: none;
  border: none;
}

HTML code in node-product.tpl.php:

Why Create Yet Another PHP Tutorial?

I haven't yet come across a truly simple and gradual tutorial for complete beginners that explains PHP from the very basics. Most tutorials assume you already know what a function, recursion, variable, or data type is—as if everyone has C++, Pascal, or Basic ingrained in their memory.

In this part of the PHP tutorial we will go over the basics of the PHP language from the very beginning. As you learn more and more about PHP, the examples will become more complex.

This lesson marks the real beginning of our PHP journey. Here, we’ll start executing PHP scripts and generating HTML pages using PHP code. Right from the first lesson—we’re diving in! I’ve intentionally named this one "Lesson 1" because I prefer action over lengthy introductions. If you’re curious about the history of programming languages or PHP itself, you can explore that later on your own.
