How to build the jQuery Functions on Our Website

In order to build jQuery function on a website, you will need to apply several steps which will be explained more below. But before you go to the next discussion, you should firstly pay attention to this introduction. For beginners, choosing the way for declaring JavaScript function could be quite confusing. You need to know why and how you use them in writing jQuery code. This is because there are some different ways for such purposes using jQuery or JavaScript.

From Loading JavaScript Library up to Putting Things Off Together

Apparently, jQuery can be used to build the web widget as well. Web Widgets are component of web page chunk which is provided to another people with the purpose of displaying the data for your site on their page. It typically contains of HTML, JavaScript, and CSS in slightly complex mixture. You will probably want to make that complexity hidden. Widget which is developed could also be embedded within web page using only two tags of HTML. Code which is referenced with script tag is going to take care the downloading of different assets and update container’s content.

Now, let’s back to the topic of how to build jQuery function in the website. The following description might help you to explain the steps ranging from loading the JavaScript library until putting things together.

·         Load JavaScript library

First step to follow is that you have to load JavaScript in library. Create local variable to hold your jQuery version and then check presence of jQuery version you need. You will be strict about version number. However, you could use regular expression that can match the version of major number. You can do this once you have tested the code with some versions. You can create script element simply that points to library file URL. This is needed for loading the library. When there is a problem of page which is written poorly and has no head, you can simply append the script tag to the element of document.

·         Load the data from site

This step is called “load data from our site”. In this point, you will load JavaScript file taken from server using the request of GET HTTP and then you execute it. You just can use the regular AJAX if host page is located in same domain. There might be security restriction as well. But the browser allows the use of script tags to deal with security restriction.

·         Load the CSS

Another step you need to follow is loading CSS. For loading the stylesheets, you can create link tag by using JavaScript. If you want to dynamically load CSS stylesheets after HTML page you have has loaded, you can use jQuery to help you achieve that purpose through few code line.

·         Put things together

The last step to do is putting things off together. After you have seen different bits, you could put things together and then build simple example. When you find some errors in host pages later, you are suggested to write the custom code in order to test whether the pages are ready or not.
