Searching for attributes without values in HTML tags using Selenium.

This method specifically checks for attributes with a value:

public boolean isAttribtuePresent(String element, String attribute) { 
    Boolean result = false; 
    String value = "vvv"; 
    // element = "Month ''May'' @xpath=//button[text()='Jun']"; 
    try { 
        value = webElement.getAttribute(attribute); 
        if (value != null) { 
            result = true; 
        } 
    } catch (Exception e) {  
        System.out.print(e.toString()); 
    } 
    System.out.print("***"+value+"*****"); 
    return result; 
}

Answer №1

To determine if the attribute value is not null, simply use this function:

const hasAttrValue = (element, attribute) => element.getAttribute(attribute) != null

console.log(hasAttrValue(radioBtn1, 'checked'))
console.log(hasAttrValue(radioBtn2, 'checked'))
<input id="radioBtn1" type="radio" name="nradio" value="1" checked>
<input id="radioBtn2" type="radio" name="nradio" value="2">

Answer №2

When using element.getAttribute(attributeName), you will receive a null value in two scenarios: 1. When the attribute does not have a value assigned to it 2. When the attribute is simply not present within the element

Answer №3
