| Subject | CTRL use on canvas. |
| Message-ID | <e008ff78-09a2-4981-b28a-12a635a3140bo@googlegroups.com> |
I have started a "silly" project trying to simulate some sort of text editor/command cursor format on canvas. Shift seem to work implicity, chosing correct Charcode character, but CTRL charcode 17 just produce some rectangle symbol. Should i just have some boolean on/off switch for CTRL and simply reposition charcode with an add x or subtract x. Or is there some type of command that actually make it do what shift does?

Is the above is correct, is this also the way to do for other keys like the numberic keyboard? What keyboard things will simply not canvas be able to handle?

Please provide a proper context for once.

Look at an ASCII table. What did you expect charcode 17 to display?

What did you expect charcode 17 to display? Ok i was a bit tired this morning so forget that question, but i have a connected question, when i . and ,"echo" dot it correctly tells me keycode 188 and keycode 190. But what is echoed out is 3/4 and !/4 symbols, i know is is something with i am echoing wrong type of value. key = e.keyCode ? e.keyCode : e.which; character= String.fromCharCode(key);

Those are old browser specific properties from before the standards were defined. Use this instead: <https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key>

No, this is called a ternary operator and many languages have this. Also see <https://en.wikipedia.org/wiki/%3F:> -- Arno Welzel https://arnowelzel.de
