Question

How do I get the value of each key pressed and use it in a variable with jQuery? I want to get a key pressed and reveal a certain picture on the page that correlates to that key right when it is pressed. I also ONLY want to target A-Z and “.”

Thanks!

Using jQuery, you can use the keypress event, and then convert the character to a string, and match it against your criteria.

Here’s a working example:

$(document).keypress(function(e)
{
    var s = String.fromCharCode(e.which);
    if (s.match(/[a-zA-Z\.]/))
        console.log(s + ' is a match!');
});

Update: For the key pressed inside another element, just use the selector $('#LearnStart'), as seen here.
