How do I link to the jQuery files?

How do I link to the jQuery files?

You can download the jQuery libray file or files to your own computer. Save them to a folder called js in a directory where you are going to put your jQuery practice files. In the <head> section of each practice file you will want to add the following line:

<script type="text/javascript" src="/js/jquery-1.11.1.min.js"></script>

Be sure the name of the .js file shown in the src="/" area above matches the name of the file that you downloaded from jQuery.

You can also choose to link directly to the files on the Google server. These Google library files include jQuery, jQuery Mobile and jQuery UI documentation. Click here to access the various Google Library Files for jQuery. At this link there are snippets of code that you will place in the <head> section f your practice document so that the links retreive the correct files.

Find out exactly how to link to the jQuery files in the JQ Zemplate article: Obtaining and linking to jQuery files

How is jQ.Zemplate going to help me to learn jQuery?

jQ.zemplate is not intending to replicate any existing sites that elaborate on jQuery. What we are attempting to do is present some of the information in a simplified manner that is easier for the beginning web developer to grasp. The resources for jQuery are vast, but at times are aimed for those with a great deal of coding experience. The beauty of jQuery and jQuery UI is that you don't have to be a power-coder to be able to use its functionality.

This site is divided into several sections. With each section is a series of articles to assist you with the learning process. When learning jQuery, some of the terms and concepts can seem a bit obscure until you actually apply them while creating script for a web page. You may need to refer back to reference articles while coding to get the full understanding.

jQuery is written in JavaScript. The syntax and logic is often very similar, though jQuery has many shortcuts and is targeted for cross-browser appearance and functionality.

It is best to have a solid understanding of JavaScript when working with jQuery. This section introduces the basic concepts, syntax and logic of JavaScript.

Basic jQuery Concepts

This section covers the underlying concepts of jQuery. A good understanding of what is happening as the code is run can save many hours of frustration.

When you get the basics down, there is so much more that you can do with the jQuery interface.

jQuery API Methods

JQuery API Methods are convenient shortcuts for manipulation of HTML objects. They can be combined for advanced functionality.

Each jQuery API has an explanation of their use, examples for a better understanding and snippets of code that you can cut and paste elsewhere.

jQuery UI

jQuery UI is a set of library files that create widgets, interactions and effects. These files aid web developers to do common tasks that use jQuery without having to rewrite lengthy code. Some of these widgets are: accordion menus, autocomplete for forms, sliders, spinners, tabs, etc. 

This section of our website displays some of the things that you can do using jQuery UI functionality.


Learning by example can be the most enlightening approach. The tutorials start with easy steps with just a few methods introduced in each. Later tutorials get into more complex code for the intermediate user.

You may find it useful to come back to the tutorials just to copy and paste some of the script for other projects.


The Demo section has a variety of demos using jQuery and JavaScript. This is to highlight what all can be done with jQuery for animations, forms, games, quizzes and a multitude of other applications


The dialog section has articles about specific uses for jQuery, discusses common problems, clever applications, and other topics.

How to ...

The How To ... section has a list of articles on how to do some commonly needed functions with JavaScript and jQuery.


The resources section allows for quick reference to resources for jQuery files. Is also has numerous reference lists for JavaScript Operators, Regular Expressions, jQuery Selectors and other things.
