keypress

I would like to be able to close a ModalWindow when the user presses a key, in my case ESC. I have a Javascript listener for the keypress which calls the click event of the cancel button's ID: jQuery("#"+modalWindowInfo.closeButtonId).click(); Is this the correct way to do it? I am wondering because it works in Chrome but not in FF, but it could be due my specific implementation. tetsuo The 'right' way to do it is to call the server, then close it with the response. You can do this with an ajax behavior: ModalTestPage.java public class ModalTestPage extends WebPage { public ModalTestPage

I need to capture user's backspaces inside an input. So I've done this: <input type="text" ui-keypress="{8:'removeTagOnBackspace()'}" ng-model="searchStudent" /> And then, inside my controller I've done this, just to check if it's working: $scope.removeTagOnBackspace = function() { console.log('here'); }; But is not printing anything. What is wrong with this? Is angular able to capture backspaces? Got it! <input type="text" ng-keydown="removeTagOnBackspace($event)" /> And: $scope.removeTagOnBackspace = function (event) { if (event.keyCode === 8) { console.log('here!'); } }; 来源： https:/

I need to detect when someone hits "enter" in text inputs with a specific class. My jQuery is as follows: $('input.large').keypress(function (e) { if(e.which ==13) console.log("pressed enter"); }); My HTML is something like this: <tr><td> Personal Name </td></tr> <tr><td> <input type='text' class='large'> </td></tr> <tr><td> Email</td></tr> <tr><td> <input type='text' class='large'> </td></tr> When I've given the fields IDs and tried $('#elementid').keypress it worked. But this isn't working. I get no console output. What am I missing? You can use live ( .on() ) events in document with keydown

I need to invoke a key press event in android . Any suggestions ????? You need to use the instrumentation class : Instrumentation i = new Instrumentation(); i.sendKeyDownUpSync(KeyEvent.KEYCODE_A); This should be equivalent to a A pressed on the keyboard. The following example shows how to invoke Key Back key event: KeyEvent eventDown = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK); KeyEvent eventUp = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK); dispatchKeyEvent(eventDown); dispatchKeyEvent(eventUp); 来源： https://stackoverflow.com/questions/3361281/invoke-keypress-event

Good morning everybody! I have a case, when I should prevent users to entering space as a first character on input field. I have a demo here: http://jsbin.com/foyetolo/2/edit It works only when you hit spacebar for first time. When you start typing other characters and select whole text in input (ctrl+a) and then hit the space bar it adds the space in the beginning of input field. So, how to check if on keypress/keydown if the first character will be a space, return false and not allow it to type the space as a first character? You can do this by checking if key is space and selection start is
