Question

decimal number validation with + and - symbol

Answer 1

+3 A:

You don't need jquery for that, you can use an expression for this:

if (/(\+|\-)\d{2}\.\d{2}/.test(value)) {
  // validated
}

Untested though, but something like this should work fine.

I'd use `/[+-]\d{2}\.\d{2}/`, otherwise that's fine.

@Peter Kruithof - i need to do an inline validation..so i can use this with .change function rite?

@Peter Kruithof @Tim Pietzcker - i tried out like this. but always returns .bad$('#retinoscopy_ltl').change(function(){var vals = $('#retinoscopy_ltl').val();if (/[+-]\d{2}\.\d{2}/.vals) {alert('looks gud');}else{alert('bad');}});

@pradeep I've tested the expression at http://www.regular-expressions.info/javascriptexample.html and it works just fine (be sure to leave the leading/trailing slash out when testing). I'd start debugging the value if I were you and test that using your regex.
