在selenium中使用css选择器进行元素定位

Sizzle Css3还提供一些直接选取form表单元素的伪类

• :input: Finds all input elements (includes textareas, selects, and buttons).
• :text, :checkbox, :file, :password, :submit, :image, :reset, :button: Finds the input element with the specified input type (:button also finds button elements).

下面是一些XPATH和CSS的同义locator比较

定位方式	XPath	CSS
标签	//div	div
By id	//div[@id='eleid']	div#eleid
By class	//div[@class='eleclass'] //div[contains(@class,'eleclass')]	div.eleclass
By 属性	//div[@title='Move mouse here']	div[title=Move mouse here] div[title^=Move] div[title$=here] div[title*=mouse]
定位子元素	//div[@id='eleid']/* //div/h1	div#eleid >* div#eleid >h1
定位后代元素	//div[@id='eleid']//h1	div h1
By index	//li[6]	li:nth(5)
By content	//a[contains(.,'Issue 1164')]	a:contains(Issue 1164)
根据子元素回溯定位父元素	//li[a[contains(.,'Issue 1244')]] //*[./a[contains(.,'Issue 1244')]] //ul[.//a[contains(.,'Issue 1244')]]	li{a:contains(Issue 1244)} ul{a:contains(Issue 1244)}
根据邻近元素定位	//li[preceding-sibling::li[contains(.,'Issue 1244')]] //ul[preceding-sibling::ul[.//a[contains(.,'Issue 1244')]]]	css=li:contains(Issue 1244) + li css=ul{a:contains(Issue 1244)} ~ ul
