• JQuery Knob display number change 3 answers

I'm using jQuery plugin called Jquery Knob http://anthonyterrien.com/knob/

To create circular progress bar ,

So here's my code

<input type="text" value="90" class="dial" data-width="80" data-height="90" data-readOnly=true data-fgColor="#2ecc71">

JS Knob Execute

$(".dial").knob();

Tried to append ( % ) to value attribute but it's not rendered

$('.dial').each(function() {

  $(this).attr("value", $(this).attr("value") + "%");

});

Any Suggestions ? Thanks !

回答1:

As of version 1.2.7 of this plugin there is a format hook that you can use to change the way that the number is displayed.

For example you can specify:

$(".dial").knob({
  'format' : function (value) {
     return value + '%';
  }
});

Use below code it will work

$(".dial").knob({
 'change': function (v) { console.log(v); },
  draw: function () {
  $(this.i).val(this.cv + '%');
  }
 });
