I'm trying to create this slider
http://jqueryui.com/demos/slider/#rangemax
Is it possible to parametrize the max value?
For ex:
$("#slider-range-max").slider({
range: "max",
min: 1,
max: maxValue,
value: 2,
slide: function(event, ui) {
$("#amount").val(ui.value);
}
});
Is it possible to pass maxValue value, when I click on something? After its been initialized? Not on document ready function, but even after that?
You can set the values at any time, for max you'd do this:
$("#slider-range-max").slider("option", "max", newValue);
You can see how to do this with all the options at the jQuery UI site. Here's an example:
$(".increaseMax").click(function() {
var currentMax = $("#slider-range-max").slider("option", "max");
$("#slider-range-max").slider("option", "max", currentMax + 1);
});
According to the page you gave in your question (click on Options and then max):
Get or set the max option, after init.
//getter
var max = $( ".selector" ).slider( "option", "max" );
//setter
$( ".selector" ).slider( "option", "max", 7 );
Change 7 to any value/variable you want to set the new maximum value to.

Firstly, please note I am new to jQuery and have limited js experience, so this may be a silly question, but I have no one to ask for help.
I have a jQuery range slider which provides two year values. I have successfully created a variable which contains both the minimum and maximum year.
I am unsure how to update the min/max year variables after the user interacts with the range slider.
I need the the min/max year values as variables to use as a filter for a map/geojson query.
I have tried to declare the variable equal to ui.value(0) and ui.value[0], but that is as far as I have gotten. (example: yrmin = ui.value[0]; )
The only thing I know for certain is that I don't know enough. Any direction, comments, suggestions, or links to related exercises/ problems etc would be so incredibly helpful.
var yrmin = '';
var yrmax = '';
$( function() {
$( "#slider-range" ).slider({
range: true,
min: 1900,
max: 2020,
values: [ 1945, 1995 ],
slide: function( event, ui ) {
$( "#amount" ).val( " " + ui.values[ 0 ] + " - " + ui.values[ 1 ] );
}
});
$( "#amount" ).val( " " + $( "#slider-range" ).slider( "values", 0 ) +
" - " + $( "#slider-range" ).slider( "values", 1 ) );
yrmin = $("#slider-range").slider("values", 0);
yrmax = $("#slider-range").slider("values", 1);
});
When I use the the yrmin = ui.value(0); the console logs a ui not defined error..
You can use (window), but I do recommend to avoid the global approach as much as you can
window scope
window.yrmin = $("#slider-range").slider("values", 0);
window.yrmax = $("#slider-range").slider("values", 1);
Probably most stupid question ever, but it is really annoying, the code compiles well and work great with range numbers 0 to 100, however, I cannot figure out why my slider control stop working when I use numbers greater than 100 ... I'm using simple jquery-ui sample
and all looks good, but soon as change numbers greater then 100 (due to our requirements we want to use it for years), the select list stop changing the dates and slider doesn't move ... Does it support numbers greater then 100 or there is some limitations ?! js code I'm using:
$(function() {
var select = $( "#minbeds" );
var slider = $( "<div id='slider'></div>" ).insertAfter( select ).slider({
min: 100,
max: 1000,
step: 100,
range: "min",
create: function( event, ui ) {
setSliderTicks(event.target);
},
value: select[ 0 ].selectedIndex + 1,
slide: function( event, ui ) {
select[ 0 ].selectedIndex = ui.value - 1;
}
});
$( "#minbeds" ).change(function() {
slider.slider( "value", this.selectedIndex + 1 );
});
});
function setSliderTicks(el) {
var $slider = $(el);
var max = $slider.slider("option", "max");
var min = $slider.slider("option", "min");
var spacing = 100 / (max - min);
$slider.find('.ui-slider-tick-mark').remove();
for (var i = 0; i < max-min ; i++) {
$('<span class="ui-slider-tick-mark"></span>').css('left', (spacing * i) + '%').appendTo($slider);
}
}
and here is HTML:
<form id="reservation">
<select name="minbeds" id="minbeds">
<option>100</option>
<option>200</option>
<option>300</option>
<option>400</option>
<option>500</option>
<option>600</option>
<option>700</option>
<option>800</option>
<option>900</option>
<option>1000</option>
</select>
</form>
And some CSS styles for tick-marks:
.ui-slider-tick-mark{
display:inline-block;
width:2px;
background:grey;
height:16px;
position:absolute;
top:-1px;
}
Can anyone please let me know, what is wrong with it, and in case if there are some limitations, can anyone recommend me some other library to use (open source), with the same functionality, taking input from html (select list) and with tick-marks/labels available ?! Any help appreciated ! Thank you.
The problem is that you simply copy pasted the example and expect it to work without understanding how it works even though you have a different requirement.
The demo is using selectedIndex property directly because the values are ranging from 1-6 and the slider steps by one. Your values and steps are different so if you want to find the option to select by index, you should divide the slider value by step value which is 100 and subtract 1 (since the options index is 0 based). Similarly if you want to set the slider value based on selected option index, you should increment it by 1 and multiply by 100.
Instead of doing all that you can simply use the selected options value and slider value directly like:
$(function() {
var select = $("#minbeds");
var slider = $("<div id='slider'></div>").insertAfter(select).slider({
min: 100,
max: 1000,
step: 100,
range: "min",
value: 100,
slide: function(event, ui) {
select.val(ui.value);
}
});
$("#minbeds").change(function() {
slider.slider("value", this.value);
});
});

I'm developing an APP using jquery mobile with phonegap. Have a trouble when trying to retrieve the value of a slider, for some reason I can't take it, i've got something like
$(document).ready(function() {
var iValue = 0;
$("#sliderVer").uislider({
min : 10,
max : 100,
orientation : "vertical",
step : 1,
value : iValue
});
$("#incomplete_field_correo").hide();
$("#incomplete_field_secret").hide();
$("#incorrect_field_correo").hide();
});
I've tried with
$("sliderVer").value;
also
$("sliderVer").slider( "value" );
and
$("sliderVer").slider( ui.slider );
But nothing seems to work, any idea?
thanks in advance!
Get or set the value option, after initialization:
// getter
var value = $( ".selector" ).slider( "option", "value" );
// setter
$( ".selector" ).slider( "option", "value", 10 );
http://api.jqueryui.com/slider/#option-value
$(function() {
$( "#slider" ).slider({
range: "min",
value: 2,
min: 0,
max: 5,
slide: function( event, ui ) {
// While sliding update the value
$( "#image" ).pixastic('blurfast', {amount:ui.value});
}
});
// Set the initial slider amount
var value = $( "#slider" ).slider( "value" );
$( "#image" ).pixastic('blurfast', {amount:value});
});
I've got multiple sliders for pixastic effects on an image. However every time the slider updates the image, I want it to revert the old effect and apply the new level of that effect rather than the effect accumulating each time. I'm aware of the revert function in the pixastic library, but I'm fairly new with jquery and unsure how to use it. How could I go about doing this?
$("#image").click(function(){
Pixastic.revert(document.getElementById('image'));
//apply your new effect.
});
This is the code for my jquery ui slider:
var slidervalue = 100;
$(function () {
$( "#slider" ).slider({
range: "min",
value: 100,
min: 1,
max: 700,
slide: function( event, ui ) {
$( "#amount" ).val(ui.value );
slidervalue = ui.value;
}
});
$( "#amount" ).val( $( "#slider" ).slider( "value" ) );
});
And this is a extra the function i have created to fetch a number from my deal title and calculate savings and display the result.
function updateSlider() {
$.each($('.coupontitle'),function(index,coupObj){
if ($(coupObj).text().match(/(\d+)\%/i))
{
var percent = $(coupObj).text().match(/(\d+)\%/i);
var savings = ((percent[1]*.01) * slidervalue).toFixed(0);
$('span',coupObj).html('Save: $'+savings);
}
else if ($(coupObj).text().match(/\$(\d+)/i))
{
var percent = $(coupObj).text().match(/\$(\d+)/i);
var savings = ((percent[1]*.01) * 100).toFixed(0);
$('span',coupObj).html('Save: $'+savings);
}
});
}
this code is working properly along with the slider. right now, when a user slides the slider the amount corresponding to the slider is passed using ui.value and is passed to the above function and is calculated.
But, when i input a value into the text box manually, i want the slider to move automatically, and i want that value to pass into the function to calculate. Right now, when a amount is entered manually, the input value is not passed into the function.
I want the slider to work as this site: http://www.chippmunk.com/
I came across this jsfiddle, which does the work, but when manually entered it is not passing the text box value into my function to carry on with the calculation.

The accepted answer above is very useful and it works fine for single value sliders. But someone like me might wonder how to control two values in Range Slider.
So, if we use range slider, we need to pass an array as values and for range slider we can handle it like this
var min_val = 0;
var max_val = 1000;
function minMaxControl(type) {
if (type == 'min') {
min_val = $('#min').val();
} else if (type == 'max') {
max_val = $('#max').val();
}
$("#slider-range").slider('values', [min_val, max_val]);
}
$("#slider-range").slider({
range: true,
min: 0,
max: 1000,
values: [min_val, max_val],
slide: function(event, ui) {
$("#min").val(ui.values[0]);
$("#max").val(ui.values[1]);
}
});
You can see the full code and demo here. https://jsfiddle.net/N4K1B/2tv9phke/1/
So basically in above answer the single parameter of the slider was controlled like this:
$("#slider").slider("value",this.value);
And for range slider instead of passing a single value we are passing an array of two values like this:
$("#slider-range").slider('values', [min_val, max_val]);
Hope this answer may help someone if someone is still using jquery-ui slider.
For more, please refer to the documentation
This will work, I would move the $-sign out of the input though.
http://jsfiddle.net/Rusln/MD3mX/847/
$("#slider").slider({
range: "min",
value: 1,
step: 1000,
min: 0,
max: 5000000,
slide: function (event, ui) {
$("input").val(ui.value);
}
});
$("input").change(function () {
$("#slider").slider("value",this.value);
});
UPDATE
http://jsfiddle.net/Rusln/KLj6Z/
$("#slider").slider({
range: "min",
value: 1,
step: 1,
min: 0,
max: 100,
slide: function (event, ui) {
$("input").val(ui.value);
}
});
$("input").on("keyup",function(e){
$("#slider").slider("value",this.value);
});
