javascript - jquery ui slider comparing values after sliding -


i'm trying value of slider when value goes or goes down.

$(document).ready(function() {     var valmap = [1,2,3,4,5,6,7,8,9,10];      var counter = null;     var slider = $( "#slider" ).slider({       disabled: false,       animate: true,       min: 0,       max: valmap.length-1,       values: [0],       slide: function( event, ui ) {         $( "#zomlevel" ).val(valmap[ui.values[0]] + "x");         slider.slider("option", "animate", "slow");         counter++;         if(counter increments){ alert("counter increments"); } if(counter decrement){ alert("counter decrements"); }       }     }); });

if slide slider right should increment , if slide slider left should decrement. how can in slider?

try like

jquery(function($){      var valmap = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];     var counter = null, value= 0;     var slider = $("#slider").slider({         disabled : false,         animate : true,         min : 0,         max : valmap.length - 1,         slide : function(event, ui) {             //$("#zomlevel").val(valmap[ui.values[0]] + "x");             slider.slider("option", "animate", "slow");             counter++;          },         change: function(){             var val = $(this).slider('value');              console.log(val, value)             if(value < val) {               console.log('incremented')             } else if(value > val){               console.log('decremented')             }             value = val;         }     });   });
