在 Watir 的 Wiki 上无意中看到的，激动的热泪盈眶啊，实在是佩服的五体投地，感谢这些热心的同行们整理了这些宝贵的资料啊。同志们，我们都要向国外的“雷锋”学习啊！
另外，也建议大家从中学习一下文档整理和编写的技巧。

| :id | Used to find an element that has an "id=" attribute. Since each id should be unique, according to the XHTML specification, this is recommended as the most reliable method to find an object. * |
| :name | Used to find an element that has a "name=" attribute. This is useful for older versions of HTML, but "name" is deprecated in XHTML. * |
| :value | Used to find a text field with a given default value, or a button with a given caption, or a text field |
| :text | Used for links, spans, divs and other element that contain text. |
| :index | Used to find the nth element of the specified type on a page. For example, button(:index, 2) finds the second button. Current versions of WATIR use 1-based indexing, but future versions will use 0-based indexing. |
| :class | Used for an element that has a "class=" attribute. |
| :title | Used for an element that has a "title=" attribute. |
| :xpath | Finds the item using xpath query. |
| :method | Used only for forms, the method attribute of a form is either GET or POST. |
| :action | Used only for form elements, specifies the URL where the form is to be submitted. |
| :href | Used to identify a link by its "href=" attribute. |
| :src | Used to identify an image by its URL. |
* :id and :name are the quickest of these to process, and so should be used when possible to speed up scripts.
