Implementing Infinite Scroll in jQuery

Summary of key points Infinite scrolling (also known as lazy loading or no paging) is an alternative to paging, which loads new content via Ajax when the user completes scrolling of existing content on the page.

To avoid problems with search engines, alternatives with paging or site maps should be provided. Implementing infinite scrolling includes creating basic HTML and CSS layouts, setting up Ajax modes for processing requests, appending new data to the page, and ending processing data. The implementation of infinite scrolling can be further improved by deleting the button and calling the function when the user scrolls down to the end of the page, by

When JavaScript Feature Detection Fails

Key Points Feature detection of JavaScript (testing features that programmers want to use) is not always reliable. For example, test ActiveXObject in Internet Explorer for Ajax requests, HTML attributes mapped to DOM properties, assumptions about user behavior (such as detecting touch devices), etc. When feature detection fails, browser detection is sometimes required. However, it is recommended to use proprietary object testing instead of navigator information and use it to exclude browsers rather than include them. Be extremely careful when implementing browser detection. Always assume that the feature test is fully in line with, only if you know a certain feature
