ReactJS: Modeling Bi-Directional Infinite Scrolling

阅读更多关于 ReactJS: Modeling Bi-Directional Infinite Scrolling

Our application uses infinite scrolling to navigate large lists of heterogenous items. There are a few wrinkles: It's common for our users to have a list of 10,000 items and need to scroll through 3k+. These are rich items, so we can only have a few hundred in the DOM before browser performance becomes unacceptable. The items are of varying heights. The items may contain images and we allow the user to jump to a specific date. This is tricky because the user can jump to a point in the list where we need to load images above the viewport, which would push the content down when they load.

I use the following js to decide which divs are shown. eg from homepage <script> $(".list_item_image").mouseenter(function () { $

How do you implement infinite scroll on data that you get from firebase. So far I found an angularjs directive , that works really great but I'm having difficulty implementing it with fireable as firebase returns all data in one single request and this is not what I want. Few weeks ago, I made a JS function that allowed an infinite scrolling in my app . First, a set of data is displayed when the user visit the website: // Add a callback that is triggered for each message. var n = 25; // Step size for messages display. $(window).load(function() { lastMessagesQuery = messagesRef.limit(n);

问题 My first question is how do they get this scroll bar? http://dl.dropbox.com/u/12337149/scrollbar.png I have seen it in a few places so I presume it might be in a public library? My second question relates to the infinite scrolling itself. Once again I have seen it on a few sites so is it a technique that is relatively common and is described somewhere? 回答1: Do you mean the "lazy load" effect like on Twitter (when you scroll, it loads more when you reach the bottom)?
