Question

So I’m trying to create an infinite scrolling table using AngularJS, similar to this: http://jsfiddle.net/vojtajina/U7Bz9/

The problem I’m having is that in the jsfiddle example, if I keep scrolling till I have a million results, the browser is going to slow to a crawl, wouldn’t it? Because there would now be 1,000,000 results in $scope.items. It would be better if I only ever had, for example, 1000 results at a time inside $scope.items, and the results I was viewing happen to be within those 1000.

Example use case: page loads and I see the first 10 results (out of 1,000,000). Even though I only see 10, the first 1000 results are actually loaded. I then scroll to the very bottom of the list to see the last 10 items. If I scroll back up to the top again, I would expect that the top 10 results will have to be loaded again from the server.

I have a project I did with ExtJS that a similar situation: an infinite scrolling list with several thousand results in it. The ExtJS way to handle this was to load the current page of results, then pre-load a couple of extra pages of results as well. At any one time though, there was only ever 10 pages of results stored locally.

So I guess my question is how would I go about implementing this in AngularJS? I kow I haven’t provided much code, so I’m not expecting people to just give the coded answer, but at least some advice in which direction to go.

Answer 1

So turns out that the ng-grid module for AngularJS has pretty much exactly what I needed. If you look at the examples page, the Server-Side Processing Example is also an infinite scrolling list that only loads the data that is needed.

Thanks to those who commented and answered anyway.
