为什么波动存在？(Why does volatile exist?)

 为了避免“未编译内容的闪存”，请使用ng-bind而不是{{}}或使用ng-cloak ： 
 
<span ng-cloak ng-show="show">Hello, {{name}}!</span>
 
 如果您使用ng-cloak，并且您不将Angular.js加载到HTML的头部，则需要将其添加到CSS文件中，并确保它在页面顶部加载： 
 
[ng\:cloak], [ng-cloak], .ng-cloak { display: none; }
 
 请注意，您只需要在初始页面上使用这些指令。 稍后提取的内容（例如，通过ng-include，ng-view等）将在浏览器渲染之前由Angular进行编译。 
 
 
 
 是否有更好的方式加载除了ng-show / hide之外的数据，其中只有相关部分被加载到DOM中。 
 
 
 ng-show / ng-hide的一些替代方案是ng-include ， ng-switch和（自v1.1.5） ng-if ： 
 
<div ng-include src="someModelPropertySetToThePartialYouWantToLoadRightNow"></div>
 
 另见https://stackoverflow.com/a/12584774/215945 ，了解ng-switch与ng-include一起使用的示例。 
 
 请注意，ng-switch和ng-if添加/删除DOM元素，而ng-show / hide只会更改CSS（如果对您很重要）。 

To avoid the "flash of uncompiled content", use ng-bind instead of {{}} or use ng-cloak:
 
<span ng-cloak ng-show="show">Hello, {{name}}!</span>
 
If you use ng-cloak, and you do not load Angular.js in the head section of your HTML, you will need to add this to your CSS file, and ensure it loads at the top of your page:
 
[ng\:cloak], [ng-cloak], .ng-cloak { display: none; }
 
Note that you only need to use these directives on your initial page. Content that is pulled in later (e.g., via ng-include, ng-view, etc.) will be compiled by Angular before the browser renders.
 
 
 
Is there a better way to load data other than ng-show / hide, in which only the relevant section is loaded into the DOM.
 
 
Some alternatives to ng-show/ng-hide are ng-include, ng-switch and (since v1.1.5) ng-if:
 
<div ng-include src="someModelPropertySetToThePartialYouWantToLoadRightNow"></div>
 
See also https://stackoverflow.com/a/12584774/215945 for an example of ng-switch working together with ng-include.
 
Note that ng-switch and ng-if add/remove DOM elements, whereas ng-show/hide only alters the CSS (if that matters to you).
