Identifying whether the user has activated the browser back button has been a persistent challenge in web development. This question explores various techniques for achieving this goal, particularly in single-page applications that utilize hash navigation.
One popular approach involves using window.onhashchange, which tracks any hash changes in the URL. However, this method also triggers when in-page elements modify the hash, often leading to an inconsistent user experience.
Instead, the recommended method is to create an array that stores previous hash values as the user navigates the interface. By continuously updating this array using window.location.lasthash.push(window.location.hash), the system maintains a history of hash changes.
Additionally, to distinguish between the browser back button and in-page back buttons, the solution utilizes mouse events. By setting a boolean flag window.innerDocClick to true when the mouse is within the document area and false when it leaves, the system can track whether the user is using the browser back button or an in-page back button.
This mechanism allows for more granular control over hash changes, enabling developers to handle browser back button events separately and implement custom in-page navigation.
Furthermore, to prevent backspace keystrokes from triggering the back event, the solution incorporates a jQuery event handler that intercepts backspace keys for non-input elements. By swallowing these events, it ensures that the user does not inadvertently navigate backward when using backspace to clear form fields or text editor input.

The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.
