With <input type="number">, if a user enters "abc" for example, the specs says to handle that as if the value is an empty string. However, should the UA even allow the user to enter those characters in the field? It seems like if the keypress is not one of "-+.e0123456789" (or "," instead of "." depending on the locale), then the keypress should be prevented. Or, if a value that's pasted into the field that's invalid should be prevented. Or, is validation only meant for when it's time to submit? Now, with JS, you might be able to do this with listening for keypress and preventing it. But, to catch all kinds of input, you'd need to use the 'input' event or the 'change' event. But, those don't seem to be cancelable. You could revert the value though if the user inputs something invalid. Seems like the UA should do this though. Or, is this one of things where "The UA can do whatever it wants"? If so, is there any common practice that should be followed with user input in this case? -- Michael
