Calculator App Shortcuts Help

Calculator App Shortcuts Help


So I am using an external library for my calculator, here is the link:

And here is the codepen:

Basically my issue is that I can’t get my operator shortcuts to work. For example, to add a shortcut with this library you do:
shortcut.add("Ctrl+Shift+X",function() { alert("Hi there!"); });

So I want to add a shortcut for shift+(the equals button) for the plus operator.

but when I do :
it doesn’t work.

The documentation says that it supports all special characters but I cannot get it to work… If anyone has any idea of how to do this that would be great!


Maybe my question sounds a bit silly, but are you sure this is a valid key combination? On my German keyboard, Shift+= just does not exist. “=” itself is Shift+0.


On US QWERTY keyboards = is next to backspace with + as its shift value. When you press Shift + = your keyboard drivers / OS handle the built-in shortcut and pass a + to the browser.

You don’t need an external library (other than, say, jQuery to make coding easier) for that type of shortcut. What you need is to listen to keypresses.

$('#yourCalculator').bind('keypress', function(e) {


Ok, thanks! Didn’t know that was built into javascript, that library was just the first thing I saw when I searched keyboard shortcuts on google…

So I have a question now, when looking at this code:
$('#yourCalculator').bind('keypress', function(e) { console.log(e.keyCode) });

What should I set #yourCalculator to in my code? I cant seem to figure that part out.


It is a valid key combination on my keyboard.

Here is what my keyboard looks like:

As you can see, the plus and equals are on one key right next to the delete button.


To use jQuery you’ll need to review how it binds events to elements on the page. In the case of your code you’d probably bind it to either $(body) or $(’.calculator’) if you’re alright with the user needing to select the calculator before input is grabbed.

Wow thanks! Got all the operator keys working!
