HTML源码 |
Watir代码 |
说明 |
:action |
<form action=”page.htm”> |
ie.form(:action, /page/).click |
只可用于form元素, |
:after? |
<a>one</a> <a>two</a> <a>one</a> |
ie.link(:after?, ie.link(:text, “two”)).click |
定位到指定元素之后的页面控件 |
:class |
<a> |
ie.link(:class, “header”).click |
当元素有class属性时可以使用其进行定位、识别 |
:for |
<label for=”header”> |
ie.label(:for, “header”).click |
只可用于定位label元素 |
:href |
<a href=”page.htm”> |
ie.link(:href, /page/).click |
可使用href属性定位超链接 |
:id |
<a> |
ie.link(:id, “header”).click |
用于通过id识别控件,由于xhtml说明中定义了id唯一,推荐使用这种最为可靠的识别方式 |
:index |
<button> |
ie.button(:index, 1).click |
用于定位页面指定类别第N个元素。目前的Watir版本中从index为1开始计数,但以后可能会从0开始计数。 |
:method |
<form method=”get”> |
ie.form(:method, “get”).click |
仅可用于定位form元素,form的method属性值可以是get或post |
:name |
<a> |
ie.link(:name, “header”).click |
用于通过name属性识别元素,对于之前版本的HTML比较有用,但对于XHTML来说识别度较低。 |
:src |
<img src=”photo.png”> |
ie.image(:src, /photo/).click |
当需要通过URL来识别一个图片元素时使用 |
:text |
<a>click me</a> |
ie.link(:text, “click me”).click |
可用于识别包含文本的页面元素,如link,span,div等 |
:title |
<a title=”header”> |
ie.link(:title, “header”).click |
识别含有title属性的元素 |
:value |
<input value=”text”> |
ie.text_field(:value, “text”).click |
用于识别含有默认值的text field元素或button元素 |
:url |
<a href=”page.htm”> |
ie.link(:url, /page/).click |
url属性和href属性相同 |
xpath |
<a href=”page.htm”> |
ie.link(:xpath,”//a[@href='page.htm']“).click |
使用xpath定位元素 |
multiple attribute |
<a>click me</a> <a>click me</a> |
ie.link(:text => “click me”, :index => 2).click |
可以使用多个属性联合定位识别,如本例所示,将点击文本为”click me”的第二个链接 |
例如:browser.links.each do |link|
puts link.href
end
