![]() ![]() This method is the same as the getElementsByName() method. In JavaScript, we can use the getElementsByTagName() method to access all the elements with the given tag name. Var temp = document.getElementsByName("attrName") Accessing the element by getElementsByName method ![]() Return value − It returns the collection of elements that have a particular name. Parameter − It takes input for the name of the element that the user wants to access. Syntax document.getElementsByName(element_name) The name here is the attribute name of the HTML element. It helps the user to get an element with the help of a name. In JavaScript, we can access elements by using the getElementsByName() method. Var temp = document.getElementsB圜lassName("className") Accessing the element by getElementsByclassName method Users can access this collection using the indexes. Return value − It returns the collection of objects that have a particular class name. Parameter − It takes input for class names of the element that needs to be accessed. Syntax document.getElementsB圜lassName(classnames) In this we are going to use the method getElementsB圜lassName() to get and update the element. We can provide a class name to each element in HTML and then access the same using that class name. This selects the element from the class name. Var temp = document.getElementById("elementId") Accessing the element by getElementById method If the element with the particular id doesn’t exist, null is returned. Return value − It returns the object with the particular id. Parameter − It takes the element id for the element to be accessed. Syntax document.getElementById(element_ID) If any element does not exist with the given Id, the method returns null. Users can use the getElementById() method to access and update the HTML content. This method gets the element from a unique ID and lets the user access that element. To facilitate this, we can move ahead and change the HTML element by using the following techniques −īelow we have added the demonstration for the above methods. We can support this by using modern-day JavaScript. In HTML, sometimes the user needs to access the HTML elements to display the user different changes. ![]()
