The problem with this approach to baselining is that there are no semantics implied by the label name - except those implied by how you use the tool 使用这种方式进行基线化的问题在于,没有由标签名所暗指的语意上的含义除了那些提示你如何使用这个工具。
The getelementsbytagname ( ) method returns all elements ( as a nodelist ) with the specified tag name that are descendants of the element you are on when using this method 方法(以一个节点列表的形式)返回了指定标签名的所有元素,这些标签名称是该方法所作用的元素的孙类元素。
Labeling is a process by which you select a label name and then attach that label name to one or more file versions . by attaching the same name to a number of different file versions , you get a pseudo - baseline 打标签是一个过程,通过此过程,你可以选择一个标签名,然后将此标签名附在一个或多个文件版本上通过将相同的名字粘附在许多不同的文件版本上,你就可以得到一个基线。
