backspace

I am trying to make a console like application, so I am catching all the keypress on the window and do related stuff with them(not important). Problem is at backspace. I have the following code: $(window).bind("keypress",function(e){ var code = e.keyCode || e.which; if ( code == 8) { a = $("#console").html(); $("#console").html(a.substring(0,a.length-1)); currentCommand = currentCommand.substring(0,currentCommand.length-1); e.preventDefault(); } However, in Firefox, contents of the #console is deleted but Chrome does not execute the code above. I need a cross-browser compatible solution. What

My backspace key in Eclipse Mars (4.5.0) works like the delete key: it deletes the right character instead of the left one. That's really confusing Maybe I accidentally used a shortcut key? I tried to restart Eclipse but it didn't work. I also tried to switch the key binding preferences to "Emacs" scheme before reverting to "Default" but that didn't work either.

But I don't know what's going on inside of this function. let char = string.cString(using: String.Encoding.utf8)! let isBackSpace = strcmp(char, "\\b") if isBackSpace == -92 { print("Backspace was pressed") return false } I don't know why the result of cString of backspace is 0. I can debug on XCode. Please check the screenshot. I don't know why the strcmp about 0 for backspace(as far as I got this value on XCode debugger) and "\b"
