java - 在selenium中选择cssselection时显示异常

Question

<h3 class="menuheader expandable " headerindex="1h"><span class="accordprefix"></span>

<h3 class="menuheader expandable " headerindex="2h"><span class="accordprefix"></span>
<h3 class="menuheader expandable " headerindex="3h"><span class="accordprefix"></span>

我们的应用程序具有上述 header 。每个 header 都将 headerindex 作为唯一值进行识别。我使用了以下代码:

WebElement Tab_selection = driver.findElement(By.cssSelector("<h3>[headerindex=2h]"));
Tab_selection.click();

但它显示了异常:

invalid selector: An invalid or illegal selector was specified. Could you please help on that

Answer 1

您需要将 2h 括在引号中 ( explanation ):

h3[headerindex="2h"]

<小时/>

并且，xpath 定位器始终是一种替代方案:

By.xpath("//h3[@headerindex='2h']")
