Multiple Installation Options: The web developers have option to install jQuery in two distinct ways. They can download the library to their local system, and then include it in HTML code. Otherwise, they can integrate jQuery directly into the HTML code by using a content delivery network (CDN). The CDN enables users to make the web browser cache jQuery across various applications.
DOM Manipulation: Many web developers nowadays try to enhance the performance of the web application through document object model (DOM) manipulation. JQuery enables programmers to manipulate DOM without writing additional code. The developers can avail specific methods like .val(), .html() and .attr() to simplify DOM manipulation. These methods further help programmers to quickly accomplish tasks like modifying value of attributes of an element and extracting HTML code from a division.
AJAX Calls: The web developers can further use jQuery to build AJAX templates without putting extra time and effort. Hence, the developers can keep the user interface of the web application slick by creating and using a variety of custom AJAX templates. Also, they can perform common tasks without refreshing or reloading the web page fully. Hence, jQuery enables developers to make the website deliver dynamic and update content to each user without writing lengthy and complex code.
Increased Search Engine Ranking: Major search engines like Google ranks websites by using a variety of metrics. Also, the search engines need to access and read the source code of the web application without any hurdles. Hence, web developers have to explore ways to make the source code of a website fully readable and accessible for search engines. JQuery along with all its components are set up as text. The search engines will rank the website higher by accessing and reading its source code fully.
