Question

I would like to define a maskRe in javascript that only allows values from 0.002 – 0.1 to be entered in a form, any ideas?

On top of this, I would like to create a regex in javascript that only allows values from 0 – 50.00 to be entered in a form, any ideas?

Answer 1

Please understand that maskRe should be used to filter out invalid symbols – but not to validate value of an input: regex property should be used for this.

You can use both, though:

maskRe: /[0-9.]/,
regex: /^0[.](1|0[1-9][0-9]?|00[2-9])$/

… or …

regex: /^0[.](1|0[1-9][0-9]*|00[2-9][0-9]*)$/

… if you don’t need to limit number of digits after the decimal point to three.

UPDATE: for 0 – 50.00 it would be something like this, perhaps…

regex: /^(50(?:[.]0+)?|[1-4]?[0-9](?:[.][0-9]+)?)$/
