Accessing the element by class name and Accessing the element by id using querySelector Var temp = document.querySelector(".tutorialsPoint") Return value − The querySelector() method returns the first object that matches thecCSS selectors, while the querySelectorAll() method returns a collection of all objectscthat match the CSS selectors. Parameter − As a parameter, it accepts different CSS selectors such as class, tag name, and id. Syntax document.querySelector(selectors) The querySelectorAll() method returns all element that matches the particular CSS selector. The querySelector() method returns the first element that matches the particular CSS selector. HTML elements can be retrieved using CSS selectors in two ways. We can select the HTML elements by using the CSS selectors such as class Id, and tagName. Var temp = document.getElementsByTagName("p") Return value − It returns the collection of elements that includes the tag name passed as a parameter. Parameter − It takes input for the tag name Syntax document.getElementsByTagName(Tag_name) Here, we are accessing the elements using the tag name instead of using the name of the element. 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. ![]() Most of the cases InnerHTML property is used for writing dynamic html content like registration form, feedback form, comment form, etc. InnerHTML property is also used for writing dynamic html content on html documents. This selects the element from the class name. InnerHTML property is used for modifying the HTML content from JavaScript code. 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. The boxes HTML Collection has three items in it which can be then iterated using for.of loop.In HTML, sometimes the user needs to access the HTML elements to display the user different changes. It gets all div elements from the entire document and returns an array-like object called HTMLCollection. The getElementsByTagName() method takes one argument which is the tag name. const spanBoxes = document.getElementsByTagName("span") Ĭonsole.log(spanBoxes) // HTMLCollectionĬall the getElementsByTagName() on the global document object. In the below HTML example, there are three div elements and two span elements. Learn how to get one or more elements by tag name using the getElementsByTagName() method.
