如何在 Watir 中识别各种 HTML 对象(全/更新到 2007-6-20)

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。

The HTML Elements that are currently supported include:

button <input> tags with type=button, submit, image or reset radio <input> tags with the type=radio; known as radio buttons check_box <input> tags with type=checkbox text_field <input> tags with the type=text (single-line), type=textarea (multi-line), and type=password hidden <input> tags with type=hidden select_list <select> tags, known as drop-downs or drop-down lists label <label> tags (including "for" attribute) span <span> tags div <div> tags p <p> (paragraph) tags link <a> (anchor) tags table <table> tags, including row and cell methods for accessing nested elements. image <img> tags form <form> tags frame frames, including both the <frame> elements and the corresponding pages. map <map> tags area <area> tags li <li> tags

: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.
