jquery only allow input float number

Question

i\'m making some input mask that allows only float number. But current problem is I can\'t check if multiple dots entered. Can you check those dots and prevent it for me?

Answer 1

One-more plugin, based on Carlos Castillo answer

https://github.com/nikita-vanyasin/jquery.numberfield.js

Adds method to jQuery object:

$('input.my_number_field').numberField(options);

where options is (you can pass any or no options):

{
    ints: 2, // digits count to the left from separator
    floats: 6, // digits count to the right from separator
    separator: "."
}
