How to Prevent Multiple Resize Event Triggers in Web Development?

Addressing Multiple Resizing Event Triggers with Delayed Execution

In web development, the resize event is often used to respond to changes in the browser window's dimensions. However, this event can get triggered multiple times during the resizing process, leading to inefficient and potentially undesirable behavior. To address this issue, it's possible to wait for the end of the resize event before executing an action.

Delayed Event Execution

One approach to handling this situation is to use JavaScript's setTimeout() and clearTimeout() functions to introduce a delay between the moment the resize event is triggered and the actual execution of an action. Here's a code example:

function resizedw () {
  // Execute your action here, as the resize event has ended.
}

var doit;
window.onresize = function () {
  clearTimeout(doit);
  doit = setTimeout(resizedw, 100);
};

In this code, the resizedw() function is executed after a delay of 100 milliseconds using setTimeout(). This delay ensures that the action is only triggered when the resize event has ended. The clearTimeout() function is used to cancel any previously scheduled timeout, preventing multiple executions of the action.

Additional Considerations

Using a delay can introduce a slight lag in the user experience, especially if the delay is too long. It's important to find an appropriate delay that balances responsiveness with event suppression. Alternatively, sophisticated event handling frameworks like RxJS can be used to handle complex event scenarios like this with a higher degree of control.
