Is there a way to use Javascript in a browser to make the escape key on the keyboard go back?
For instance, when visiting this page and clicking the "Fullscreen" link, it would be great to simply press the escape key and return to the previous page.
What is the trick in Javascript to achieve this magic?
To implement a Key-Listener, you can use the following code snippet:
window.addEventListener("keyup", function(e){ if(e.keyCode == 27) history.back(); }, false);
Once the user presses the Escape key (keycode 27), the history.back() function will be executed.
$(document).on("keydown", null, function(event) {
if (event.keyCode == 27) { //execute function for escape key
//code to navigate back
}
});
To enable the functionality to go back in history when the Escape key (keycode 27) is pressed, you can attach an event listener for the onkeyup event on the window object and then check if the keycode matches the Escape key. If it does, the window.history.back() function will be triggered.
window.onkeyup = function(e) {
if (e.keyCode == 27) window.history.back();
}
You can find more information about the window.history property in the MDC documentation available at https://developer.mozilla.org/en/DOM/window.history
Simply wait for code 27 and execute history.go(-1);
To trigger the back action when the 'ESC' key is pressed, you must listen for the keypress event and check if the keycode is equal to 27, like shown below:
document.onkeydown = function(e){
if (window.event.keyCode == 27) {
history.go(-1);
}
};
