How to check if element contains specific class attribute
The answer provided by @drkthng works but you might have a case where the class name is a subset of another class name. For example:
<li class="list-group-item ng-scope active">text</li>
If you wanted to find the class "item" then the provided answer would give a false positive. You might want to try something like this:
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;
}
Given you already found your element and you want to check for a certain class inside the class-attribute:
public boolean hasClass(WebElement element) {
String classes = element.getAttribute("class");
for (String c : classes.split(" ")) {
if (c.equals(theClassYouAreSearching)) {
return true;
}
}
return false;
}
#EDIT As @aurelius rightly pointed out, there is an even simpler way (that doesn't work very well):
public boolean elementHasClass(WebElement element, String active) {
return element.getAttribute("class").contains(active);
}
This approach looks simpler but has one big caveat:
As pointed out by @JuanMendes you will run into problems if the class-name you're searching for is a substring of other class-names:
for example class="test-a test-b", searching for class.contains("test") will return true but it should be false
#EDIT 2 Try combining the two code snippets:
public boolean elementHasClass(WebElement element, String active) {
return Arrays.asList(element.getAttribute("class").split(" ")).contains(active);
}
That should fix your caveat.
