How do you obtain the key value in OnKeyPress handler?

[boylesg]

<script>

 

function doOnKeyPrerss(Event)

{

alert(Event.charCode);

alert(Event.keyIdentifier);

}

 

</script>

 

Neither of these work - I just get 'undefined'.

 

So how do you obtain the key value?

How is the function being called? If it's through an attribute on the element then it won't work. The event handler has to be assigned through code:

element.addEventListener("keypress", doOnKeyPress, false);// For IE 8 and underelement.attachEvent("onkeypress", doOnKeyPress)

I think I can forget the idea of field validation in javascript altogether.

 

It appears to be impossibly cumbersome.

 

I think I will just stick with field validation in php.

to find the key that is pressed use something like this:

var key = event.key || event.keyCode || event.which;alert(key); 

event.key seems to be the upcoming standard way of getting the key, but hasn't been implemented as of yet. keyCode and which are the current recommendations of grabbing the character, yet they are slated to be depreciated and won't be recommended soon. the code I show here "should" give you the right property regardless of version or platform.
