javascript - Jquery ui slider move to the next value -


here's sample image of i'm trying accomplish

enter image description here

say click 150 value handle should move 50 , not jump 150. click again move 50 100.

the other way around, handle on value 150 click on value 5, should not jump directly 5 should move 150 100.

how can that?

here's code:

var valmap = [5, 10, 20, 50, 100, 150]; value = 0; var slider = $("#slider").slider({     disabled: false,     animate: true,     min: 0,     max: valmap.length - 1,     slide: function (event, ui) {         slider.slider("option", "animate", "slow");      },     change: function () {          var slideval = $(this).slider('value');         console.log(slideval, value)         if(value < slideval) {             console.log("incremented")         } else if(value > slideval) {             console.log("decremented")         }         value = slideval;     } });

here's sample jsfiddle: http://jsfiddle.net/endl3ss/jnwww/21/
