I'm grateful for the answers but they none of them are working on my
system. One textbox contains for example the value "2 100". This should
be treated as "2100" but is treated like "NaN".
Maybe it's easier to say that space, dot or comma should be eliminated.
<input onchange="
this.value=this.value.replace(/\./g,'').replace(/\,/g,'').replace(/\ /g, '');"
Will remove any commas, any dots and any spaces from the input. Test it :)
And if the user by mistake writes anything else than numbers it should
be treated like "0" so that they always get a correct sum.
So, if I type in "Randy Webb" instead of 123, it should deduce that I meant 0? Test it for all digits after removing spaces commas and periods. Then, if it contains non-digits you tell the user they have incorrect input.
