问题描述

我用这段代码显示缩略图列表:

I'm displaying a list of thumbnails with this code:

<div class ="channel" ng-repeat ="channel in UIModel.channels" ng-class ="{evenchannel: ($index % 2) == 0, oddchannel: ($index % 2) == 1}">
            <img class="channel-img" ng-src ="data/channels/{{$index + 1}}/thumb"/>
</div>

在控制器中,我有一个抓取新缩略图的ajax请求。 Angular因此更新图像,但会导致闪烁。有没有办法在更新DOM的过程中将缓冲区加倍或者没有删除列表?

In the controller I have an ajax request which grabs new thumbnail images. Angular thus updates the images but causes flickering. Is there a way to double buffer or not have the list deleted in the process of updating the DOM?

推荐答案

@ cexbrayat的答案,如果你没有任何ID,你也可以把它关联起来, track by $ index 。这是ng-repeat期间的内部迭代。

To go along with @cexbrayat's answer, if you don't have any IDs you can also just associated it and track by $index. Which is an internal iteration # during an ng-repeat.

<div ng-repeat="channel in UIModel.channels track by $index"></div>
