Cem*_*mre 9 javascript fouc zurb-foundation angularjs
我使用AngularJS创建了一个简单的应用程序.当我打开页面一秒钟时,我会看到下面的屏幕:
但是,在加载完成后,我看到加载和样式化的内容很好:
如何防止页面上的AngularJS代码闪存？这与FOUC有关吗？
这是HTML代码:

ng-cloak在某种程度上会有所帮助,但您可以使用ng-bind指令而不是使用来完全阻止它{{ }}.
例如
<td ng-bind="val.monthly"> </td>
不
<td>{{val.monthly}}</td>
- 这有另一个优点,即您可以在加载模板之前提供一些默认文本.例如`<h1 ng-bind ="title">正在加载...... </ h1>` (6认同)
这已经很长时间了,但这是我的工作解决方案:
您需要ng-cloak在html的body标签上使用但最重要的部分是下面的CSS:
[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
display: none !important;
}
对我来说,我必须添加这个以使ng-cloak工作.这可能不是解决这个问题的唯一方法,可以在其他答案中看到.希望这有助于某人.
