javascript - Disable submit button until input fields are filled -


this website link, here have been trying using jquery code enable/disable button not succeed achieve. inspect element see code please , output off course there

tushar's solution working perfectly. recommend use formal/standard approach validation.

do not disable submit button. use required attribute each radio button either in html like

<input id="input_5_0_1" class="form-radio" type="radio" required="required"  name="customer_appointment" value="good" />

or using js (its short cut way) like

$(document).ready(function () {         $('form input').attr('required','required');         });

demo on fiddle

this way not able submit until fill fields, though button not disabled.

however if have use button disable approach can follow above answer of @tushar

edit solution works modern browsers support html5. browsers other mentioned in link http://html5readiness.com/ (e.g internet explorer 4,5,6) not support html5
