That means this event is called whenever the URL changes.// target elements with the 'draggable' class interact ( '.draggable' ). This example adds an onresize event to the window1 popup window described in previous examples. Replace the alert statement with the code you’d like to run when a resize event occurs. javascript resize event call function javascript remove event window resize detect resize window javascript window evenet listener resize html resize with window window.addeventlistener 'resize' monitor window width change event javascript on resize window js window resize to method if width resize javascript resize event listener on. Whenever a new page is navigated history.pushState is called and page is added to the state. This code tells JavaScript to execute the code within the function whenever a window resizes. When the function is called in lines () and (), the given values are copied to local variables from and text.Then the function uses them. The history API maintains complete the navigation state. Javascript does not provide any native listener to path change (not hashchange). This works as expected (partially), whenever the page is loaded the XHR is sent, but gatsby do not reload the page while changing the URL when any blog link is clicked, so XHR is sent only once per session and not on subsequent page loads. Just call the function inside your page as same as you would write JavaScript inside the body of a page. We created a function sendTelemetry and called it on window.onload. The blog is built using gatsby, we wanted to add google analytics to this, but instead of using google tag manager, we tried to restrict what data is sent to google and in this process, we need to send XHR request on every page load. Things like shifting elements around the dom as required by design often results in a mess that is a pain to work through later down the line. We run into a situation where we need to call a function whenever URL path changes (not the hash). By the end of a project, my script.js file is normally full of functions, many are needed to be called on load and resize, and just thought if there is a better and more structured approach to do this. But since there is no page reload, window.onload event does not get triggered for subsequent navigation. Syntax: (selector).resize (function) Parameter: This method accepts single parameter function which is optional.

Modern JS frameworks tend not to reload the page but manipulate DOM and change URL path for internal navigation, for performance and smooth UX.
