Tip: To get the size of an element, use the clientWidth, clientHeight, innerWidth. For a more generic approach, you can always use the window resize event. 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 :) The onresize event occurs when the browser window has been resized. If you reach a too low quality factor (ex. ![]() Up to 37x faster than related approaches (read section 5 of the article ). ResizeId = setTimeout (doneResizing, 500 ) īasically what we do in this case is adding a timeout of 500 milliseconds to call our function doneResizing. Check if the result size in bytes: if the size is greater than 10MB, repeat the compression with a lower quality factor. element-resize-detector Optimized cross-browser resize listener for elements. 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 ![]() Sometimes we need to execute functions which might take a while to execute or which might consume quite a few resources from the machine. It can accept three, five, or nine parameters and has the following syntax. We can use it to resize and crop our images by passing an appropriate number of arguments. JQuery resize event (or Javascript one) is fired when the size of the browser's window (viewport) changes as pointed out in jQuery documentation.
