The script that follows contains the onresize function. Here in the body we are printing the count of how many times the window is resized. This example helps in resizing an existing window and also keeps a count of it.ĭocument.getElementsByTagName("BODY").onresize = function() ĭocument.getElementById("demo").innerHTML = txt The working of the onresize function is very easy. We use the above syntax for listening to the events. We will also need the addEventListener() method which can be used as below: object.addEventListener("resize", m圜ode) This function will be responsible for handling the argument sent by the FocusEvent object and take care of it. See the code below.The functionName is a function name or a function expression which will be receiving the FocusEvent object as its only argument. For example, let’s add an event to the object window to get its width and height and show it on the web page. This function is used to specify what will happen if the size of a window is being changed. To add a resize event to the window, we can use the onresize() function in JavaScript. Add a Resize Event Using the onresize() Function in JavaScript You can also use the addEventListener() function to add an event to any object, like a checkbox. You can save the above code into an HTML file and open it with any browser and change its size to see if the code works or not. The width and height of the window will be shown on the page, and it will change as the size of the window is changed. After the start() function, we added the resize event, which will call the start() function when a user resizes the window. In the script tag, we have a function start(), which is used to change the text of the two spans with the width and height of the window. The id of the span will be used to get the element in JavaScript. We added a br tag to move the cursor to a new line, and on the new line, we added another span with text Height=, and after that, we added another empty span with an id SpanID2. In the above code, we added a span with text Width=, and after that, we added an empty span with an id SpanID1 in the body section.
