我建立一个自定义的AngularJS指令来创建一个谷歌地图，我已经在我的自定义标签内存储的属性部分的谷歌地图选项：

I'm building a custom AngularJS directive to create a google map, and I've stored some of the google map options in custom attributes within my tag:

<googlemap zoom-control="true" …></googlemap>

角的指令编译方法有参数（tElement，tAttrs，transclude）;当我登录 tAttrs 到控制台，该对象已转换连字符驼峰与名称属性：

Angular's directive compile method has parameters (tElement, tAttrs, transclude); when I log tAttrs to the console, the object has properties with names that have converted hyphens to camelCase:

谁在做这个角或浏览器（在Firefox和放大器检查;浏览器）？我可以依靠这种行为？

Who is doing this—Angular or the browser (checked in Firefox & Chrome)? Can I rely on this behaviour?

P.S。当我检查的DOM中，HTML元素的属性还是有连字符。

P.S. When I check the DOM, the attributes of the html element still have hyphens.

推荐答案

角是做什么的。是的，你可以依靠它：

Angular is doing it. Yes you can rely on it:

从属性页：

一个共享对象的属性。该数值反映了当前绑定状态{{}}。需要正常化，因为所有这些都为等同于角处理：搜索    ＆LT;跨度NG：绑定=一个NG绑定=数据-NG-绑定=一个X-NG-绑定=一个＆GT;

A shared object between directive compile / linking functions which contains normalized DOM element attributes. The the values reflect current binding state {{ }}. The normalization is needed since all of these are treated as equivalent in Angular: <span ng:bind="a" ng-bind="a" data-ng-bind="a" x-ng-bind="a">
