Jquery ui slider move to the next value - javascript

Here's a sample image of what i'm trying to accomplish
Say I click from 150 value the handle should only move to 50 and not jump to 150. I click again it move from 50 to 100.
The other way around, say the handle is on value 150 then i click on value 5, it should not jump directly to 5 it should move from 150 to 100.
How can I do that?
Here's my 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 a sample jsfiddle: http://jsfiddle.net/endl3ss/jNwww/21/

I don't know the slider too much, but here is a working solution based on your specification:
http://jsfiddle.net/5xMMz/11/
and here is the full code for reference
var valMap = [5, 10, 20, 50, 100, 150,500,1000,5000];
value= 0;
var lastSlideValue = 0;
var internalSlideCalling = false;
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');
if (!internalSlideCalling)
{
if (Slideval>lastSlideValue && lastSlideValue < $(this).slider('option','max'))
{
Slideval = lastSlideValue+1;
}
else if (lastSlideValue > $(this).slider('option','min'))
{
Slideval = lastSlideValue-1;
}
lastSlideValue = Slideval;
}
console.log(Slideval, value)
if(value < Slideval) {
console.log("incremented")
} else if(value > Slideval){
console.log("decremented")
}
value = Slideval;
if (!internalSlideCalling){
internalSlideCalling = true;
$(this).slider('value',Slideval);
}
else
internalSlideCalling = false;
}
});
$("#slider").slider('values',valMap);

Then you can use event which will raise when we move slider and then set the value for slider.We can manually set the slider value.
This is event code
slide: function( event, ui ) {
// code
},
$('#id').slider("value",value); //using this we can set the slider value

Use
$("#slider").slider({
step: 50
})

How to add units to roundslider's values?

I have a roundslider widget and I am trying to add units to its values, when value = 0-999 then Hz unit should show up next to the value, and when value = 1000-999999 then it is KHz ... so on so forth.
This is my original slider:
$("#slider").roundSlider({
sliderType: "min-range",
radius: 150,
handleSize: "+12",
mouseScrollAction: true,
min: 0,
max: 100000000,
value: 0, // default value at start
change: function(event) {
$.getJSON('/set_Frequency/' + event.value);
}
});
And here is my non working attempt:
$("#slider").roundSlider({
sliderType: "min-range",
radius: 150,
handleSize: "+12",
mouseScrollAction: true,
min: 0,
max: 100000000,
value: 0, // default value at start
//change: function(event) { $.getJSON('/valueofslider', {slide1_val: event.value}); }
change: function(event) {
var value = event.value, content;
if (value <= 999) content = "Hz";
else if (value <= 999999) content = "KHz";
else if (value >= 1000000) content = "MHz";
else content = "GHz";
$.getJSON('/set_Frequency/' + event.value + content);
}
});
Can you help please?
For any formatting you can use the tooltipFormat event. I hope for your scenario you want to select any value from Hz - GHz.
I have updated the demo based on your required logic. Here you can select the value from 1 kHz to 100 MHz.

And, if you can show your actual use-case scenario then I can do a better suggestion for your requirement.

jQuery UI Slider Missing BG

I'm using a range slider with jQuery UI but when I move the slider, the background line does not show up so it's hard to tell where it is at. How do I highlight the background line only for the selected portion?
jsfiddle is below.
https://jsfiddle.net/zbmt5qrn/
/* INTEREST RATE SLIDER */
$("#interestRange").slider({
min: 0,
max: 100,
step: 1,
values: [10],
slide: function(event, ui) {
for (var i = 0; i < ui.values.length; ++i) {
$("input.interestValue[data-index=" + i + "]").val(ui.values[i]);
}
}
});
$("input.interestValue").change(function() {
var $this = $(this);
$("#interestValue").slider("values", $this.data("index"), $this.val());
});
function handleInterestChange(input) {
if (input.value < 0) input.value = 0;
if (input.value > 24) input.value = 24;
}
var items =[ '8%','24%'];
var oneBig = 100 / (items.length - 1);
$.each(items, function(key,value){
var w = oneBig;
if(key === 0 || key === items.length-1)
w = oneBig/2;
$("#interestLabel").append("<label style='width: "+w+"%'>"+value+"</laben>");
});
I am removing the code about '8%/24%' because it does not seem to be relevant to this question.
There are a couple ways to set the background. You could insert a new element inside #interestRange and change its width based on the slider value. But if you do not need to worry about supporting outdated browsers, it would be much easier to use apply a linear-gradient to the background of #interestRange.
const sliderMin = 0
const sliderMax = 100
const sliderDefaultValue = 10
function setSliderBackground(value){
const sliderRange = sliderMax - sliderMin
const sliderPercent = Math.floor(100 * (value / sliderRange))
$("#interestRange").css({
background: `linear-gradient(90deg, #0000ff ${sliderPercent}%, #ffffff ${sliderPercent}%)`
})
}
function setSliderValue(value){
$("#interestRange").slider("value", value);
}
function setInputValue(value){
$("#interestValue").val(value)
}
$(document).ready(()=>{
$("#interestRange").slider({
min: sliderMin,
max: sliderMax,
step: 1,
// Handle when the user moves the slider
slide: (event, ui)=>{
const sliderValue = ui.value
setInputValue(sliderValue)
setSliderBackground(sliderValue)
}
})
// Handle when the user types in a value
$("#interestValue").change(()=>{
const typedValue = $("#interestValue").val()
setSliderValue(typedValue)
setSliderBackground(typedValue)
})
// Stuff to do when the page loads
setSliderValue(sliderDefaultValue)
setInputValue(sliderDefaultValue)
setSliderBackground(sliderDefaultValue)
})

How to get multiple sliders to work with java script/html/jquery

I'm currently working on a site that hosts podcasts. I have it so the podcasts plays, but I can only get very first podcast volume slider to work; the second podcast's sliders moves, but doesn't change the volume at all. Each player has a "player" id that is used to identify it. I've everything else and am stuck on this one little bug. Any help would be appreciated. Here is the javascript that creates the sliders and tries to links them to each player:
<script>
audiojs.events.ready(function()
{
var as = audiojs.createAll();
$('.slider').each(function()
{
var slider = $('.slider'),
tooltip = $('.tooltip'),
audioList = document.getElementsByTagName("audio").length;
console.log(audioList)
tooltip.hide();
slider.slider(
{
range: "min",
min: 0,
max: 100,
value: 50,
change: function()
{
for (var i = 0; i <= as.length; i++)
{
//console.log(i)
var value = $(".slider").slider("value");
document.getElementById("player").volume = (value / 100);
};
},
start:function(event,ui)
{
tooltip.fadeIn('fast');
},
slide: function(event, ui)
{
var volume = $('.volume'),
value = $(".slider").slider("value");
document.getElementById("player").volume = (value / 100);
tooltip.css('left',value / 2).text(ui.value);
if(value <= 5)
{
volume.css('background-position', '0 0');
}
else if (value <= 25)
{
volume.css('background-position', '0 -25px');
}
else if (value <= 75)
{
volume.css('background-position', '0 -50px');
}
else
{
volume.css('background-position', '0 -75px');
};
},
stop:function(event,ui)
{
tooltip.fadeOut('fast');
},});});}); </script>

jQuery UI Slider displays initial value on lowest setting

I have the following script for a jQuery UI slider. The script shows the amount in a div with id #skizzar_payment_amount
When I scroll to the lowest amount (0), the value in the div shows the initial amount instead of 0.
See here:
<script>
jQuery(function($) {
var initialValue = 7.5;
var maxValue = 20;
var stepValue = 0.25;
var sliderTooltip = function(event, ui) {
var curValue = ui.value || initialValue; // current value (when sliding) or initial value (at start)
var tooltip = '<div class="tooltip"><div class="tooltip-inner">£' + curValue + '</div><div class="tooltip-arrow"></div></div>';
$('.ui-slider-handle').html(tooltip); //attach tooltip to the slider handle
$("#skizzar_payment_amount").val(ui.value); //change amount in hidden input field
}
$("#slider").slider({
value: initialValue,
min: 0,
max: maxValue,
step: stepValue,
create: sliderTooltip,
slide: sliderTooltip,
});
$("#skizzar_payment_amount").val($("#slider").slider("value"));
});
</script>
https://jsfiddle.net/yzzvd52y/
ui.value will be 0, which is false in this line: var curValue = ui.value || initialValue;
Change it to e.g.:
var curValue = ui.value !== undefined ? ui.value : initialValue;
Updated fiddle
I updated your fiddle and added the following code:
change: function( event, ui ) {
$("#skizzar_payment_amount").val(ui.value);
}
Try this:
jQuery(function($) {
var initialValue = 7.5;
var maxValue = 20;
var stepValue = 0.25;
var sliderTooltip = function(event, ui) {
var curValue = ui.value >= 0 ? ui.value : initialValue; // current value (when sliding) or initial value (at start)
var tooltip = '<div class="tooltip"><div class="tooltip-inner">£' + curValue + '</div><div class="tooltip-arrow"></div></div>';
$('.ui-slider-handle').html(tooltip); //attach tooltip to the slider handle
$("#skizzar_payment_amount").val(ui.value); //change amount in hidden input field
}
$("#slider").slider({
value: initialValue,
min: 0,
max: maxValue,
step: stepValue,
create: sliderTooltip,
slide: sliderTooltip,
change: function(event, ui) {
$("#skizzar_payment_amount").val(ui.value);
}
});
});

jquery ui slider comparing values after sliding

I'm trying to get the value of the slider when value goes up 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 ) {
$( "#zomlevel" ).val(valMap[ui.values[0]] + "x");
slider.slider("option", "animate", "slow");
counter++;
if(counter increments){
alert("COUNTER INCREMENTS");
}
if(counter decrement){
alert("COUNTER DECREMENTS");
}
}
});
});
If i slide the slider to the right it should increment and if i slide the slider to the left it should decrement. how can i do that in slider?
Try something like
jQuery(function($){
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;
}
});
});
