I'm using JQuery Knob to make some cool graphs and it's working perfectly. But I have one problem: I want to make the display number between the graph have a '%' symbol concatenated. but I just cant seem to make it work. Modifying the input through jquery wont do it, and I've tried reading into the code of the library but with no luck. Has any one else had this problem before?
If you take a quick look at the github repo you'll see that there's a draw hook that's called everytime the canvas is drawn. If you implement that hook you should be able to add whatever you wish to the input. Here's a short example of the functionality you're looking for (to try it: http://jsfiddle.net/eAQA2/ ) and for future reference:
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="https://raw.github.com/aterrien/jQuery-Knob/master/js/jquery.knob.js"></script>
<script>
$(function() {
$(".dial").knob({
'draw' : function () {
$(this.i).val(this.cv + '%')
}
})
})
</script>
</head>
<body>
<input type="text" class="dial" data-min="0" data-max="100">
</body>
</html>
As of version 1.2.7 there is now a format
hook for performing tasks like this:
$(".dial").knob({
'format' : function (value) {
return value + '%';
}
});
