如何检查selenium web元素是否包含特定的css类。
我有这个html li元素
<li class="list-group-item ng-scope active" ng-repeat="report in lineageController.reports" ng-click="lineageController.activate(report)" ng-class="{active : lineageController.active == report}">
正如您在class属性中看到的那样,有一个活动的类。
我的问题是我有这个元素,我想根据类属性是否具有&#34; active&#34;进行检查。在其他人之间的价值,使用xpath是更优雅的解决方案。
我该怎么做?

鉴于您已找到您的元素并且您想要检查class-attribute中的某个类:
public boolean hasClass(WebElement element) {
String classes = element.getAttribute("class");
for (String c : classes.split(" ")) {
if (c.equals(theClassYouAreSearching)) {
return true;
}
}
return false;
}
正如@aurelius正确指出的那样,有一种更简单的方式(效果不佳):
public boolean elementHasClass(WebElement element, String active) {
return element.getAttribute("class").contains(active);
}
这种方法看起来更简单,但有一个重要的警告:
正如@JuanMendes所指出的,如果您要搜索的类名是其他类名的子字符串,则会遇到问题:
例如class =“test-a test-b”,搜索class.contains(“test”)将返回true但它应该为false

@drkthng提供的答案有效,但您可能会遇到类名是另一个类名的子集的情况。例如:
<li class="list-group-item ng-scope active">text</li>
如果你想找到班级“项目”,那么提供的答案会给出误报。您可能想尝试这样的事情:
public boolean hasClass(WebElement element, String htmlClass) {
String classes = element.getAttribute("class").split("\\s+");
if (classes != null) {
for (String classAttr: classes) {
if (classAttr.equals(htmlClass)) {
return true;
}
}
}
return false;
}

Simmilar与前一个,但具有java 8功能:
const joinDate = new Date(obj.date);
let snap = [
obj.name,
obj.surename,
obj.email,
obj.nip,
obj.phone,
obj.adress + " " + obj.home + " " + (obj.local=="brak" ? "" : obj.local),
obj.city,
obj.zip,
obj.spentPoint,
'',
''
];
orders.push(new Promise((resolve) => {
let userNip = i;
let ordersRef = firebase.database().ref('/orders/' + userNip);
ordersRef.once("value", (snapshot) => {
let ord = snapshot.val();
let i = 0;
for(let u in ord) {
let o = ord[u];
let newDate = new Date(o.date);
let formatttedDate = String(newDate.getDate()) + "/" + String(newDate.getMonth()+1) + "/" + String(newDate.getFullYear());
snap[10+i] = formatttedDate;
for(let x in o.items) {
snap[9+i] += String(o.items[x].title) + "[ Punktów: " + o.items[x].summary + " ]";
}
i = i + 2;
}
resolve();
})
}));
data.push(snap);

使用javascript:classList.contains
WebElement element = By.id("id");
String className = "hidden";
JavascriptExecutor js = (JavascriptExecutor) driver;
Boolean containsClass = js.executeScript("return arguments[0].classList.contains(arguments[1])", element, className);

改进@ uesports135的答案,“ classess”应为String数组。
public boolean hasClass(WebElement element, String htmlClass) {
String[] classes = element.getAttribute("class").split("\\s+");
if (classes != null) {
for (String classAttr: classes) {
if (classAttr.equals(htmlClass)) {
return true;
}
}
}
return false;
}

对于任何正在寻找 C# 实现的人:
public static class WebElementExtensions
{
private static Regex _classNameValidatorRegex = new Regex(@"^[a-z][a-z0-9\-_]*$", RegexOptions.IgnoreCase | RegexOptions.Compiled);
private static Regex _whiteSpaceRegex = new Regex(@"\s+");
public static bool HasClass(this IWebElement element, params string[] htmlClasses)
{
if (!htmlClasses.Any())
throw new ArgumentException("No html classes to match.");
if (!htmlClasses.All(c => _classNameValidatorRegex.IsMatch(c)))
throw new ArgumentException("Invalid CSS class(es) detected.");
var classAttribute = element.GetAttribute("class");
if (string.IsNullOrWhiteSpace(classAttribute))
return false;
var elementClasses = _whiteSpaceRegex.Split(classAttribute.Trim()).ToHashSet();
return htmlClasses.All(c => elementClasses.Contains(c));
}
public static bool HasAnyClass(this IWebElement element, params string[] htmlClasses)
{
if (!htmlClasses.Any())
throw new ArgumentException("No html classes to match.");
if (!htmlClasses.All(c => _classNameValidatorRegex.IsMatch(c)))
throw new ArgumentException("Invalid CSS class(es) detected.");
var classAttribute = element.GetAttribute("class");
if (string.IsNullOrWhiteSpace(classAttribute))
return false;
var elementClasses = _whiteSpaceRegex.Split(classAttribute.Trim()).ToHashSet();
return htmlClasses.Any(c => elementClasses.Contains(c));
}
}

基于常见的{classList
之前的javascript技术:
public boolean hasClass(WebElement element, String theClass) {
return (" " + element.getAttribute("class") + " ").contains(" " + theClass + " ");
}

您可以使用jquery:
$( "#yourElement" ).hasClass( "protected" )
或这个
$( "#yourElement" ).is( ".pretty.awesome" )
另一个例子
$( "#yourElement" ).is( ":hidden" )
