What about holding down a button to increase the value? Also it should get progressively faster

Don’t worry about being like css-tricks (or any other blog/author), you’re doing just fine on your own.

@Darkimmortal: I guess…”class” is a reserved word. The alternative would be what? “klass”. I prefer quotes. Also note that JSON requires quotes on everything for this reason.

oops, in my previous comment, I meant val >= 1 , not val >= 0

The test in the minus function should be val >= 0, because with != , if I type -1 in the input and press -, it keeps going down. I know it deos not really matter since the user can keep typing whatever they want, unless you make the input readonly

Anyway for the minus button function, you optimize it a little with Math.max :

input.value = Math.max(0,(input.value.toInt()-1));

I am just nitpicking. You can also set a maximum value as well with the plus button using Math.min

eheh, handy but too late for my needs…

i did have to do this only 4-5 days ago – but by relation. 4 input boxes, all numeric to increment/decrement but with the sum of the values of inputs 2,3,4 to remain less than or equal to the value of input 1. ended up with a piece of code that could be quite useful (including attachable +/- controls etc) – if i could figure how to refactor it in a way that can be reused …

btw, toInt on value “” results in a NaN so trap when users have deleted the values by hand
