Switch-Case for strings in Javascript not working as expected
- by Coltin
So I have this problem with strings and switch-case, and I'll try to keep it as simple as possible.
Here event.keyCode has the value "65", and is the result of a keydown event of 'a' (using JQuery).
if (event.keyCode == "65") {
alert("hmmmm");
}
That works, but:
switch (event.keyCode) {
case '65':
alert("Yay!");
break;
}
That doesn't. However this will work:
switch ('65') {
case '65':
alert("Yay!");
break;
}
And if I do this:
var t = '65';
switch (t) {
case '65':
alert("Yay!");
break;
}
It works. And then I tried this:
var t = event.keyCode;
switch (t) {
case '65':
alert("Yay!");
break;
}
But it fails!
So why does it match in the if-block at the beginning, but not for the switch-case?
