jQuery Knob ============= - canvas based ; no png or jpg sprites. - touch, mouse and mousewheel, keyboard events implemented. - downward compatible ; overloads an input element. Example ------- <input type="text" value="75" class="dial"> <script> $(function() { $(".dial").knob(); }); </script> Options ------- Options are provided as attributes 'data-option': <input type="text" class="dial" data-min="-50" data-max="50"> ... or in the "knob()" call : $(".dial").knob({ 'min':-50 ,'max':50 }); The following options are supported : Behaviors : * min : min value | default=0. * max : max value | default=100. * step : step size | default=1. * angleOffset : starting angle in degrees | default=0. * angleArc : arc size in degrees | default=360. * stopper : stop at min & max on keydown/mousewheel | default=true. * readOnly : disable input and events | default=false. UI : * cursor : display mode "cursor", cursor size could be changed passing a numeric value to the option, default width is used when passing boolean value "true" | default=gauge. * thickness : gauge thickness. * lineCap : gauge stroke endings. | default=butt, round=rounded line endings * width : dial width. * displayInput : default=true | false=hide input. * displayPrevious : default=false | true=displays the previous value with transparency. * fgColor : foreground color. * inputColor : input value (number) color. * font : font family. * fontWeight : font weight. * bgColor : background color.

Example ------- <input type="text" value="75" class="dial"> <script> $(".dial").knob({ 'change' : function (v) { console.log(v); } }); </script> Dynamically configure ------- <script> $('.dial') .trigger( 'configure', { "min":10, "max":40, "fgColor":"#FF0000", "skin":"tron", "cursor":true } ); </script> Set the value ------- <script> $('.dial') .val(27) .trigger('change'); </script> Supported browser ------- Tested on Chrome, Safari, Firefox, IE 9.0.
