jquery - Powerange - Change value via javascript -

-

i using powerange library in form . javascript library create ios style range bars. there plenty of options author has provided.

is there way move slider particular value via javascript programmatically? documentation doesn't has related this.

i have same problem , write code move slider particular value via javascript programmatically. see below.

/**  * set slider new value  *   * @param {object} sliderinstance   * @param {number} newvalue         */  function setslidervalue (sliderinstance, newvalue) {   console.assert( (newvalue > sliderinstance.options.min && newvalue < sliderinstance.options.max),      'new value less slider min value or greater slider max value!');   var changed = false;   var offset;   var maxvalue = sliderinstance.options.max;   var minvalue = sliderinstance.options.min;   var stepindex;   var stepsarr = (sliderinstance.options.step) ? sliderinstance.steps : null;   var value = (sliderinstance.options.decimal) ? (math.round(newvalue * 100) / 100) : math.round(newvalue);    if (!sliderinstance.options.step) {      var persentnewvalueofval = (newvalue - minvalue) * 100 / (maxvalue - minvalue);     offset = (sliderinstance.slider.offsetwidth - sliderinstance.handle.offsetwidth) * persentnewvalueofval / 100;    } else {      stepindex = ( (value - minvalue)/sliderinstance.options.step ).tofixed(0);     offset = stepsarr[+stepindex];    }    changed = (sliderinstance.element.value != value) ? true : false;   sliderinstance.setposition(offset);   sliderinstance.element.value = value;   sliderinstance.options.callback();   if (changed) sliderinstance.changeevent(); }

you can use standalone this:

var elem = document.queryselector('.js-decimal'); var init = new powerange(elem, options);  setslidervalue(init, 36);

also can update powerange.prototype. input code bellow on line 1457 in powerange.js

/**  * set slider new value.  *   * @param {number} newvalue   */  powerange.prototype.setslidervalue = function (newvalue) {   console.assert( (newvalue > this.options.min && newvalue < this.options.max),      'new value less slider min value or greater slider max value!');   var changed = false;   var offset;   var maxvalue = this.options.max;   var minvalue = this.options.min;   var stepindex;   var stepsarr = (this.options.step) ? this.steps : null;   var value = (this.options.decimal) ? (math.round(newvalue * 100) / 100) : math.round(newvalue);    if (!this.options.step) {      var persentofval = percentage.from( (newvalue - minvalue), (maxvalue - minvalue) );     offset = percentage.of( (this.slider.offsetwidth - this.handle.offsetwidth), persentofval );    } else {      stepindex = ( (value - minvalue)/this.options.step ).tofixed(0);     offset = stepsarr[+stepindex];    }    changed = (this.element.value != value) ? true : false;   this.setposition(offset);   this.element.value = value;   this.options.callback();   if (changed) this.changeevent(); };

now can use in way:

var elem = document.queryselector('.js-decimal'); var init = new powerange(elem, options);  init.setslidervalue(36);
