Example #3Įxample for getElementB圜lassName() Methodĭocument.getElementsB圜lassName('example for blue border')ĭocument.getElementsB圜lassName('example for red border')Īs similar to the above examples, here we are displaying 4 boxes of the specified length, width and color with which their borders should be made of. All the elements which are of the class “test” are shown in the output. It returns undefined when there is no matching element. Then by this function “document.getElementsB圜lassName(‘test’)” we retrieve the first element belonging to the class “test”. Same way we also fetch the matching elements which are of the class “test” and printing the same in the output. Next we are fetching the class name of the HTMLCollection “parent” with the help of getElementsB圜lassName() function. In this example, we are first declaring a few div with the text of “paragraph example” in the HTML body. VartestTarget = parent.getElementsB圜lassName("test1") To fetch a list of matching members apart from the Var test = parent.getElementsB圜lassName("test1") Var parent = document.getElementById("parent") So in the output we can see that when we click on the try button all the above text will be changed to color red who are having the class “test”. Using a for loop we assign the color red to the class named “test”. We describe a function as myTest() where we call this function getElementsB圜lassName with the same class name test. This will be done with the help of getElementsB圜lassName() function. We create a button saying “try it” in such a way that when we click on it all the div elements at the top will be changed to the specified color red. We are then specifying two div classes in the body and then a p element with the class name as “test”. In this example, we are first declaring the border and margin as per our requirements.
Var x = document.getElementsB圜lassName("test") Note: The getElementsB圜lassName() method is not supported in Internet Explorer 8 and earlier versions. This is a span element with class="test" inside another p element.Ĭlick the button to change the background color of all elements with class="test". Given below are the examples mentioned: Example #1 Examples of JavaScript getElementsB圜lassName() The returned elements will be sorted as they are seen in the source code. This function fetches and gives us an HTMLCollection object which shows an aggregation of elements with the described class name. When we need to search for multiple class names we should separate them using spaces for example like “test example”. It represents the name of the class and its elements we want to get. classname: This parameter is of type string and is a mandatory field since it is the only input parameter.
