ngAttr directive can totally be of help here, as introduced in the official documentation

(ngAttr官方文档中所介绍的那样， ngAttr指令在这里可以完全有所帮助)

https://docs.angularjs.org/guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes

(https://docs.angularjs.org/guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes)

For instance, to set the id attribute value of a div element, so that it contains an index, a view fragment might contain

(例如，要设置div元素的id属性值，以便它包含索引，视图片段可能包含)

<div ng-attr-id="{{ 'object-' + myScopeObject.index }}"></div>

which would get interpolated to

(将被内插到)

<div id="object-1"></div>
