When I press any key in my textarea, it looks like that e.keycode does not function properly. But it always triggers when I press any key in my textarea. Any help please ?
function d(e) {
var key = (e.keyCode);
if (key == 229) {
alert("hello");
return false;
}
}<textarea id="msg" onkeyup="d(event)">
</textarea>I'm not working on pc. Im testing this on android browser.
Answer 1
219 is the keyCode which need to be used
function d(e) {
var key = (e.keyCode);
if (key == 219) {
alert("hello");
return false;
}
}<textarea id="msg" onkeyup="d(event)">
</textarea>Answer 2
The keycode for { is 219. Some browser uses keycode, some uses which. There is also charCode.
function d(e){
var key = e.which || e.keyCode || e.charCode || 0;
if (key == 219){
alert("hello");
return false;
}
}<textarea id="msg" onkeyup="d(event)">
</textarea>Answer 3
try this one
<!DOCTYPE html>
<html>
<body>
<input type="text" size="40" onkeypress="myFunction(event)">
<script>
function myFunction(event) {
var x = event.which || event.keyCode;
if(x == '122'){ alert('hello');}
}
</script>
</body>
</html>
