New to front-end development and getting confused with jQuery. I have a jQuery slider with custom steps, but can't get the output to sync with the rest of my program. I think I need .addEventListener('input') to take the values produced by the slider so that the text at the bottom of the output (#infocenter) updates with the year chosen by the slider.
document.getElementById('infocenter').innerHTML = '<p>(this text should update with the year above)</p>';
var sliderAmountMap = [1940, 1950, 1960, 1970, 1980, 1990, 2009, 2015];
//new jQuery slider
$(function() {
$( "#slider" ).slider({
value: 0,
min: 0,
max: sliderAmountMap.length-1,
slide: function( event, ui ) {
$( "#amount" ).val(sliderAmountMap[ui.value] );
}
});
$( "#amount" ).val(sliderAmountMap[$( "#slider" ).slider( "value")] );
});

If I understand correctly, I think you just need to update the html of the desired element at the same time you're updating the value of the text box:
slide: function( event, ui ) {
$( "#amount" ).val(sliderAmountMap[ui.value]);
$( "#infocenter" ).html(sliderAmountMap[ui.value]);
}

I created slider using the following code available on jsfiddle:
http://jsfiddle.net/3cpsoft1/
However there is some weird behavior when the max value element of the slider is changing itself when left slider is activated.
I think this has something to do with ui part of the slider function but I don't know what is affecting it.
So at first the correct value is 0.0474 and it should stay that way. But somehow it becomes negative as if one value of step was deducted from it.
You can see that on the fiddle i provided.
Is there a way to fix this?
When you divide your total length by the step, you'll end up with a small remainder which is not able to render. Therefore, you must set it to the smallest decimal value you want slide over. Also, your max value should be outside the bound.
$( function() {
$( "#slider-range-max" ).slider({
range: true,
min: -1000,
max: 0.475,
step: .001,
values: [-1000,0.474],
slide: function( event, ui ) {
$( "#amount1" ).val( ui.values[0] );
$( "#amount2" ).val( ui.values[1] );
}
});
$( "#amount1" ).val( -1000 );
$( "#amount2" ).val( 0.474);
} );
i have a problem with jquery slider value after changing it.
I'm just using normal jquery UI (version 1.10.4) and jquery core 1.7.2
First time after refresh i have a value which i want. But after the change i can't get it. And i need that to have a if statemnet which will change a value of the paragraph.
This is a JQuery code:
$(function() {
$( "#slider" ).slider({
range:"min",
min: 0,
max: 100,
value: 10,
slide: function wynik( event, ui ) {
$( "#price" ).val("$" + ui.value);
}
});
$( "#price" ).val( "$" + $( "#slider" ).slider( "value") );
var val = $('#slider').slider("value");
if ( val >= 20 ) {
$("#priceText").text("first text");
} else {
$("#priceText").text("second text");
}
});
What is wrong here?
I want to change a text in label:
<p>
<input type="text" id="price">
<label id="priceText" for="price">Some text to change</label>
</p>
Input working correctly and show the value all the time in right way. But label doesn't change (only first time after refresh).
I have read a lot of posts on SO before i post this one. For example:
How to get value from jQuery UI slider? or How to get value from input with dynamically changed value by jquery UI slider?
But i can't get it done anyway.
You can try this:
$("#selector").change(function() {
$("#slider-range").slider('values',0,$(this).val());
});

Jquery Slider emit a "slidechange" event everytime it change value
Remember, it should be listened on the jQuery element after you've registered the event in the element itself
$( "#slider" ).slider({
change: function( event, ui ) {
// register event here
}
});
$( "#slider" ).on( "slidechange", function( event, ui ) {
// use ui.value to get the current value
} );
Check the official api wiki for all the slider related events

I've set up a JQuery UI range slider with controls, although when clicking on the controls the value sent to a select dropdown is not updated. How could I fix this?
var gmin = 0;
var gmax = 500;
var s = $( "#slider" ).slider({
value:5,
min: gmin,
max: gmax,
step: 100,
slide: function( event, ui ) {
$( "#select span" ).html(ui.value);
}
});
$('#down').click(function() {
s.slider('value', s.slider('value') + s.slider( "option", "step" ) );
});
$('#up').click(function() {
s.slider('value', s.slider('value') - s.slider( "option", "step" ) );
});

You need to use the change event, not slide here. slide() only catches manual user slides, not programmatic ones:
var s = $( "#slider" ).slider({
value:5,
min: gmin,
max: gmax,
step: 100,
change: function( event, ui ) {
$( "#select span" ).html(ui.value);
}
});
(Any reason your down button makes it go up and vice versa?)
Since this event wont store value for this element, besides here is workaround:
http://jsfiddle.net/nrNX8/514/
You have to add
$('#select span').text(s.slider('value'));
It may be useful for any element you want to set in any update.
You just need to add this line to the click functions:
$( "#select span" ).html(s.slider('value'));
...on #up and #down listeners.
However, it seems that Ivan's answer is a better approach than mine
I'm pretty new to jquery, but this is question. From my code below I have made 3 sliders each within a tag. Each of the three has an input field that is changed when the slider is moved to show the current value of the slider (simple jQueryUI plugin sliders). The final line involves another plugin that links all the sliders together so that they all add to 100 total and move when the others move.
The problem I'm having is that when I slide one, its value changes and shows but the others do not. I can get all of the values to change with some extra lines of code, but I don't know how to get (this) ui.value so that I can display the separate values for each of the sliders.
You can see in the third slider I tried to get it to do that, but the way it is set it only takes the same ui.value of the current slider being moved.
Can anyone help me with a solution to get (this) ui.value of the other sliders when i need to change it?
($(function() {
$( "#RedSlider" ).slider({
orientation: "horizontal",
range: "min",
min: 0,
max: 100,
value: 1,
animate: true,
slide: function( event, ui ) {
$( "#RedValue" ).val( ui.value );}
});
$( "#RedValue" ).val( $( "#RedSlider" ).slider( "value" ) );
});
$(function() {
$( "#BlueSlider" ).slider({
orientation: "horizontal",
range: "min",
min: 0,
max: 100,
value: 1,
animate: true,
slide: function( event, ui ) {
$( "#BlueValue" ).val( ui.value );}

$( "#BlueValue" ).val( $( "#BlueSlider" ).slider( "value" ) );
});

$( "#EmptySlider" ).slider({

{
$( "#EmptyValue" ).val( ui.value );
$( "#RedValue").val(ui.value);
$( "#BlueValue").val(ui.value);
}
});
$( "#EmptyValue" ).val( $( "#EmptySlider" ).slider( "value" ) );
$( "#RedValue").val($("RedSlider)").slider("value"));
$( "#BlueValue").val($("RedSlider)").slider("value"));
});*/
$('div:gt(2)').slider().linkedSliders({policy: 'last'});
Your code will only every be executed once. You need to change the following line:
$( "#BlueValue" ).val( $( "#BlueSlider" ).slider( "value" ) );
To be something different when selecting the value of your slider at whatever time you need it.
This code:
$( "#BlueValue" ).val( $( "#BlueSlider" ).slider( "value" ) );
will only execute once. You need to have that in a value-changed callback for the slider, so the value will be updated continually.
How to make slider with jquery, like here?
User should select a value from slider, and this value should automatically be in input
I can not find the appropriate plug-in...
http://jqueryui.com/demos/slider/
$( "#slider" ).slider({
value:100,
min: 0,
max: 500,
step: 50,
slide: function( event, ui ) {
//Its setting the slider value to the element with id "amount"
$( "#amount" ).val( "$" + ui.value );
}
});
You can customize the style to look like the example you mentioned.
