Question

以下是我在IE中使用的代码的语法：

driver.findElement(By.cssSelector("#loginForm>div>table>tbody>tr:nth-child(4)>div>span>span>span")

错误是：

org.openqa.selenium.NoSuchElementException: Unable to find element with css selector == #loginForm>div>table>tbody>tr:nth-child(4)>div>span>span>span (WARNING: The server did not provide any stacktrace information)

有人可以帮忙吗？

Answer 1

正如其他人所说，CSS3选择器无法在IE8或更低版本上运行，例如nth-child。

我在这样的时间看下面的网站，看看支持什么和什么不支持：

http://caniuse.com/#search=nth-child

至于下一步，我会做两件事：

运行最新版本的Selenium。

将您的定位器更改为类似的内容（未经过测试，因为您没有提供HTML）：

//*[@id='loginForm']/div/table/tbody/tr[4]/div/span/span/span

Answer 2

The Html code is as follows.
<form name="loginForm" id="loginForm" action="/suredesign/j_spring_security_check" method="post">
<div class="dijitLayoutContainer dijitContainer dijitTableLayout" id="dojox_layout_TableContainer_0" data-dojo-props="cols:1,spacing:10,showLabels:false" data-dojo-type="dojox.layout.TableContainer" widgetId="dojox_layout_TableContainer_0">
<table width="100%" class="tableContainer-table tableContainer-table-horiz" cellSpacing="10">
<tbody>
<tr>
<tr>
<tr>
<tr>
<td class="tableContainer-valueCell">
<div title="" class="dijitContentPane" id="dijit_layout_ContentPane_17" role="group" data-dojo-type="dijit.layout.ContentPane" widgetId="dijit_layout_ContentPane_17">
<span class="dijit dijitReset dijitInline dijitButton paddingright5 signInLabel" role="presentation" widgetId="dijit_form_Button_0">
dijitReset dijitInline dijitButtonNode

无法在IE中找到使用CSSpath的元素，尽管与使用Java的Selenium WebDriver的FF相同
