here is what I did and what you want :
<input type="text" oninput="this.value = this.value.replace(/[^0-9.]/g, ''); this.value = this.value.replace(/(\..*)\./g, '$1');" id="entry" placeholder="Enter a number" maxlength="15"/>

this is for allow only numbers. so change the regex by yours !

Answer 9

the () ?
it's included on my lesson ^^
it's to group what you want, and you can recall it with $1 (with " ")
for example
string.replace(/hi (nox)/, "hello $1");
here $1 = nox
and you can have multiple $ thanks multiple ()
