输入格式jQuery

Question

I am using this plugin: jQuery-Mask-Plugin to format inputs.

I got it working but the problem is that i want to have a range that begins from 0.0 to 6.0 maximum. It means when i put 6 i can only write 6.0 and no 6.1 or 6.3,... It is the same with 0.

demo

 $('#test_numeral').mask('a.9', { 'translation': { a: { pattern: /[0-6]/ } } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.mask/1.14.15/jquery.mask.js"></script> <input type="text" id="test_numeral"> 

Is there a way to make it work with this plugin or do you know such plugins that can do this thing?

Answer 1

You can use callback function and change its value if greater than 6.0

 $('#test_numeral').mask('a.9', { 'translation': { a: { pattern: /[0-6]/ } }, onKeyPress: function(cep, event, currentField, options) { if (cep > 6) { currentField.val('6.0'); } } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.mask/1.14.15/jquery.mask.js"></script> <input type="text" id="test_numeral">

As Pavan Sikarwar pointed out, it's great to use a callback function.

Pretty much same script as above but instead of setting the value to 6.0, I made is so that you can't type the last decimal.

let opts = {
  'translation':
  {
    a:  
    {
      pattern: /[0-6]/
    }
  },
  onKeyPress: function(cep, event, currentField, options){
    if(cep > 6.0) { currentField.val('6.'); }
  }
}

$('#test_numeral').mask('a.0', opts);
