Matching (\w+) should satisfy ES6 style classes. A simple and fairly efficient solution to getting the value of an elements class attribute is to use jQuerys. Or maybe you should ask yourself "Why am I doing this? Is this really what I am trying to solve?" If the following adds to the complexity of your decision then maybe you're looking for instanceof. There is a difference between the constructor and the actual object/class name. If you are trying to get elements with the different class names their names must be separated by whitespace and not a comma.As this was already answered, I just wanted to point out the differences in approaches on getting the constructor of an object in JavaScript.When using the aforementioned method, note that To get a complete list of classes of an element, you just need to access the classNameproperty: letclasses element.className Code language:JavaScript(javascript) Because the classis a keyword in JavaScript, the name classNameis used instead of the class. Limitation & Caveats - JavaScript get element by class: Now ‘elements’ contain the list of elements with the class name ‘item’.
Let elements = freelancer.getElementsB圜lassName('item') let docs = document.getElementByID('#freelancer') Now since we intend to look for the element in a particular section we first identify the section along with the ID. Here “name” is the class name you are looking to find and “elements” is a variable that would contain the array of elements. The syntax is as follows: var elements = document.getElementsB圜lassName(name) When the JavaScript get element by class name method is called on the document object, it searches the complete document, including the root nodes, and returns an array containing all the elements. The JavaScript getElementsB圜lassName is used to get all the elements that belong to a particular class. Using the JavaScript getElementB圜lassName() method: The below code is an example of a class attribute. This ensures that all the elements belonging to a particular class behave and appear in a similar fashion. Access the name property on the objects constructor to get the class name of the object, e.g. Once a class is created their name can be used by CSS or JavaScript to apply a particular style or to perform certain tasks. This attribute can be used on any HTML element. The class attribute is an optional property of an HTML element. Limitation & Caveats - JavaScript get element by class.Using the JavaScript getElementB圜lassName() method.
