I'm personally making use of this trick on my fullPage.js library because it does a few changes on the DOM on resize. This counter of 500 milliseconds gets restarted with every change in the window dimensions (as we clear the timeout) so the function will only be called if the user stops resizing the window OR if the user resizes the window VERY slowly, which is very unlikely :)

ResizeId = setTimeout (doneResizing, 500 ) īasically what we do in this case is adding a timeout of 500 milliseconds to call our function doneResizing. For those cases we don't usually want to execute them tens of times while the user is still re-sizing the window to reach the desired size.įor these particular cases we can use a very simple trick: var resizeId I simply want to prevent a user from resizing the browser window of a webpage to which theyve already navigated. Sometimes we need to execute functions which might take a while to execute or which might consume quite a few resources from the machine. To resize the window, you can simply do this: window.resizeTo (width, height) But this method is not working in Chrome and Opera. Here's a common debounce floating around the net, though do look for more advanced ones as featuerd in lodash.JQuery resize event (or Javascript one) is fired when the size of the browser's window (viewport) changes as pointed out in jQuery documentation.

Window.addEventListener('resize',debounce(handler, delay, immediate),false) Now whenever the browser windows size is changed, the message is appended to

one or more times, depending on the browser. javascript window resize

Tip: To get the size of an element, use the clientWidth, clientHeight, innerWidth. Use a debounce function to mitigate the excess calls. The onresize event occurs when the browser window has been resized. The resize event should never be used directly as it is fired continuously as we resize.
