backspace

Inside the KeyTyped method, how do I tell if Backspace or Esc is being pressed? BMFredrick Assuming you have attached the KeyListener properly and have implemented the methods required for that KeyListener, to detect specific key-presses simply add the following code: public void keyReleased(KeyEvent ke) { if(ke.getKeyCode() == KeyEvent.VK_BACK_SPACE) { //code to execute if backspace is pressed } if(ke.getKeyCode() == KeyEvent.VK_ESCAPE) { //code to execute if escape is pressed } } The KeyEvent class javadocs can be found at the following link: KeyEvent javadocs . There you can find a list of

I'm trying to prevent backspace button to go one page back in every browser. For now I'm using this code: $(document).on("keydown", function (e) { if (e.which === 8 && !$(e.target).is("input, textarea")) { e.preventDefault(); } }); It works fine for everything except when a select field dropdown list is opened , this event is ignored and a backspace takes me one page back anyway. How can I solve this problem? Thank you for your answers. Just for the info, this is Google Chrome specific since your code works fine in IE and FF. If you really need this to work you could render a fake dropdown and

I am building a new version of a telephone configuration manager where I am sucking on a stupid problem. You see these telephone .cfg configurations are rely static. So in the old version I made it gave the configuration without a problem. It looks like this: ## Configuration header configuration_1="parram" configuration_2="parram" configuration_3="parram" etc. Now in the new version the configuration is given as this: whitespace ## Configuration header configuration_1="parram" configuration_2="parram" configuration_3="parram" Note that white space is actually white space and that the phone

I have a function f similar to function f(str){ alert("abc"+str); } Now, I want to use JavaScript special charecter "\b" in such a way that I can choose if I want to display the hardcoded string "abc" or not. For example, f("\b\b"+"yz"); //should output "ayz" I tried the same, but it does not work. In other words, I want to concat a string with a backspace character so that I can remove last characters from the string. Can we do this in JavaScript? EDIT The real code is too much big (its a HUGE 1 liner that concats many many strings). To map that in above example, we cannot edit the function f
