A nice thing about these selection methods is they are all supported by the element or node object as well. This means you could select a parent element containing a series of child elements and select matching elements within the main parent. It does a lot of cleanup for you, etc. Its actually where the beauty of jQuery shines through. But if you really think about it, directly setting a style property is not that hard.
The following example shows how to set the marginRight property:. So where is the benefit? That means it does a lot of things and takes time. Setting the properties directly is much faster.
After DOM selection, manipulation is probably the next more important feature jQuery offers. But that too can easily be done without jQuery. Like the jQuery css method, the manipulation module us over lines of JavaScript. You can insert elements before and after target elements, select child nodes, etc. Here is an example method from my panoramaJS library. It ultimately gets the first panel and moved it to the last position in the list.
Ultimately this how the carousel is continuous in either direction. I chose this method as an example because it show how you can manipulate a node's style and move elements around all in one quick coding motion. The getFirstPanel method actually loops through the childNodes to get the first panel at this time. I am working on a cleaner solution. The reason I did that at the time is the firstChild will return a text node if there are characters before the actual first child element, admittedly one of the quirks of the native API.
I realize riding without the jQuery training wheels is not for everyone, yet. But jQuery is something every web developer should start trying to live without.
Start with using the native DOM selectors and go from there. But the beauty of jQuery is how it helped force and even provide some awesome guidance for browser manufacturers add native functionality that we as developers need to make modern web applications. But sadly as features and functionality have been added to jQuery so has the weight.
Despite the news about gigabit Ethernet and powerful CPUs, the market has gone mobile. Bandwidth and performance matter. With the average web site size reaching sizes that would not fit on a 3. My personal research routinely reveals sites using in excess of kb to perform minimal activities. Even the minimized jQuery is 91kb today. I admit there are many places where jQuery still fills a need to either make things a little easier or provide functionality that is just not available natively, that will always be the case.
But over the past few months I have found these scenarios to be less and less. If the above example had 5 insecure HTTP links on the page, the jQuery example would apply to every instance.
It would be the same code no matter if there was 1 element on the page or elements. This is not the case with vanilla JavaScript. The above example would need to be re-written to loop over each link:.
Compare this with the unchanged jQuery version and we can see the difference in not just readability but also developer productivity, since the 5 lines of code have been reduced to a single easy to understand line:. While a large portion of users have moved to modern browsers, it would be foolish to believe that everyone is currently running the most modern and up-to-date software.
Due to this, we need to make sure our scripts are compatible with a wide range of browser versions. As we have seen multiple times above, jQuery really cuts down on the amount of code written by developers. When we get rid of the boilerplate, we are left only working on the project specific logic. This increases. Web developers who have done testing and coding of CSS files will appreciate how easy jQuery implementation is. To ensure that jQuery library remains lightweight and lean, most functions have been eliminated, while others have been transferred to the plugin section.
If you need any of the omitted features, you can easily add them to your business website as plugins. This lean library helps to keep the coding at a limited level and saves on bandwidth to ensure faster loading. The main jQuery library is just 24kb and is smaller than most photographs on the webpages. For excellent web design and SEO services, consider omegaseo. Another important characteristic benefit of using jQuery is the fact that it can handle lots of cross-browser bugs and problems that are experienced while programming with JavaScript.
Handling cross-browser issues in web development can be quite a challenging experience. This is because you may find web design elements working perfectly in one browser and breaking down completely in another browser.
The jQuery library deals with most of these cross-browser issues. This means that you will develop a website that can work properly in all browser types and versions and this saves you a lot of trouble. These functions help in providing a seamless assimilation between jQuery and JavaScript. With these key utility features, the entire coding process will be easier and hassle-free. Website developers need to learn jQuery because with the comprehensive tutorials and documentation, they can create excellent websites regardless of whether they are experts or beginners in this field.
Most mobile operating systems are not compatible with the flash created animations. Although there are a lot of JavaScript libraries out there, jQuery is the most popular and widely used framework by the developers. It is more flexible and easy to use as compared to other JavaScript libraries.
It works in all browsers, makes web pages more interactive, simple, and user-friendly. Also, it can be optimized in terms of SEO and it is easy to run and use.
It helps web developers to add extra functionalities to their websites. Also, it simplifies event handling, CSS animation, and Ajax. It is much simpler with an easy-to-use API that works across a multitude of browsers.
It makes your web pages more interactive, simple and enhances user experience.
