What is jQuery?
It’s simple to change and use. Additionally, jQuery has a sizable community that offers a wealth of learning materials, assistance, and documentation.
jQuery is significantly easier to use, with a basic API that works in a variety of browsers. It improves user experience by making your web pages more dynamic and simple.
It has a number of visual features, including ease-in and ease-out effects, that make it one of the most popular options among web designers. Netflix, Google, IBM, and Microsoft are some of the big companies that use them.
- $ is used to define a query.
- (selector) is used to “query” the HTML elements in the HTML page.
- action() is the action that should be performed on the selected elements.
Features of jQuery
- The jQuery code must also be written within an HTML tag. To run the code within, we need to import/add the JS library.
- Various built-in functions can be used to manipulate DOM elements, which include adding or removing items, altering HTML text, CSS classes, and so on.
- Show or conceal elements, fade-in or fade-out of visibility, sliding effect, animation, and other special effects can be applied to DOM elements.
- The jQuery library has functions that are similar to DOM events such as click, dblclick, mouseenter, mouseleave, blur, keyup, and keydown. Cross-browser concerns are handled automatically by these functions.
- The popular JS library includes simple AJAX routines for loading data from services without having to reload the entire page.
In simple terms, selectors are used in jQuery to choose one or more HTML elements, and after the element has been selected, you can execute various operations on it.
This $ sign appears at the beginning of every jQuery selector (). The factory function is the name for this symbol.
- Tag Name is a name that can be found in the DOM.
$(‘p’) will select all ‘p’ paragraphs in the document.
- ID refers to a tag in the DOM that has a unique ID.
$(‘#abc’) picks a specific element in the document with the ID abc.
- Tag Class represents a tag in the DOM that has a defined class.
$(‘xyz’) selects all elements in the document with the xyz class.
Advantages of jQuery
- Ability to maintain basic, readable, clear, and reusable code.
- Your website can look professional if the transitions or effects are used properly.
- Plugins are easy to find because they are available everywhere on the internet.
- A few of the free jQuery plugins provide an excellent visual presentation.
Disadvantages of jQuery
- Backward compatibility is not possible with jQuery. Because there are so many published versions of the JS library, you’ll have to host the library yourself and update it on a regular basis.
- Another significant issue with jQuery is that there are numerous versions available. Some versions work well together, while others don’t.
- The development environment might become out of control if the library is implemented incorrectly as a framework.
jQuery is a sufficient library for the majority of web development projects with JS. It brings a lot of benefits to the table for web developers, therefore knowing how to use it should be a top priority.
