I have 2 input selects
Country and Cars
This is the structure: [https://jsfiddle.net/CornerStone20/r1eanhwv/6/][1]
JSFIDDLE: [1]: https://jsfiddle.net/CornerStone20/r1eanhwv/6/
When I select Country, How do I only show the selected country's cars?
I have tried:
$(function() {
$('#Country_Select').on('change', function() {
var val = this.value;
$('#Cars_Select option').hide().filter(function() {
return this.value.indexOf( val + '_' ) === 0;
})
.show();
})
.change();
});
You can use each loop to iterate through options and check if the value of car select- box is same as country select-box depending upon this show() or hide() options .
Demo Code :
$(function() {
$('#Country_Select').on('change', function() {
var val = this.value;
$('#Cars_Select option').each(function() {
//checking value of opton in cars selct is same
if ($(this).val() == val) {
$(this).show(); //show it
} else {
$(this).hide(); //hide other
}
})
})
});

// Country select
<select id="Country_Select" class="form-control">
<option selected="true" disabled="false">Choose Country</option>
<option value="0001">France</option>
<option value="8ebd9ec1-b121-44e9-a530-42f227359913">Germany</option>
<option value="4dda2683-83c6-48c8-af9b-0a96991b7c8b">New Zealand</option>
</select>
// Cars
<select id="Cars_Select" class="form-control">
<option selected="true" disabled="false">Choose Cars</option>
<option value="0001">Renauld</option>
<option value="0001">Mini</option>
<option value="0001">Paris</option>
<option value="8ebd9ec1-b121-44e9-a530-42f227359913">BMW</option>
<option value="8ebd9ec1-b121-44e9-a530-42f227359913">Audi</option>
<option value="8ebd9ec1-b121-44e9-a530-42f227359913">Mercedes</option>
<option value="8ebd9ec1-b121-44e9-a530-42f227359913">Benz</option>
<option value="4dda2683-83c6-48c8-af9b-0a96991b7c8b">Kiwi Auto</option>
</select>
Even though the question has been answered, I am writing a better approach here:
$('#Country_Select').on('change', function(e) {
let cars = $('#Cars_Select').children();
cars.hide();
let country = $(this).val();
cars.filter('[value=' + country + ']').add(cars.eq(0)).show();
});

I'm trying to get the value of the option which have the attribute "selected" to compare it to the current option selected.
function onChangeOption(opt) {
var update_value = opt.value;
var selectedValue = '???'; // get selected attribute
if (update_value != selectedValue) {
// Do some things
}
}
<select class="form-control" onchange="onChangeOption(this)">
<!-- I wanna got the content of option selected=selected-->
<option selected="selected" value="1">1</option>
<option value="2">2</option>
</select>
// save initial selected value to a variable
var initSelected = $('.form-control option:selected').val();
$('select').on('change', function() {
// check if the selected value is the same as the initial one was
if(this.value == initSelected) {
console.log('same values');
} else {
console.log('not same values');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="form-control">
<option selected="selected" value="1">1</option>
<option value="2">2</option>
</select>
Just add change event listener.And get the selected value.You can achieve comparision between selected value and changed value by maintaining an array.Like below.
values = []//creates an array
select = document.querySelector('#myselect');
values.unshift(select.value);
//console.log(values);
select.addEventListener('change',function(){
update_value = this.value;
console.log(this.value);
if (update_value != values[0]) {
// alert('Not matched');
console.log('Not matched');
}
else{
//alert('Matched');
console.log('Matched')
}
});
<select class="form-control" id="myselect">
<option selected="selected" value="1"> 1 </option>
<option value="2"> 2 </option>
</select>
I think alexis actually wants something more like this:
function onChangeOption(opt) {
var update_value = opt.value;
var options = document.getElementsByTagName("option");
if (options[0].getAttribute("selected")=="selected") {
var selectedValue = options[0].value;
} else {
var selectedValue = options[1].value;
}
if (update_value != selectedValue) {
// If the selected option's value is not equal to the value of the option with the attribute "selected", then do... (this way, you can change the attribute to any of the options!)
console.log(selectedValue);
}
}
<select class="form-control" onchange="onChangeOption(this)">
<option selected="selected" value="1">1</option>
<option value="2">2</option>
</select>
Comment the result and if you need anything else. Glad to help.
You can always store previously selected values, if you want to access them somehow later on: working example.
HTML:
<select id="mySelect" class="form-control" onchange="onChangeOption(this)">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
<p>Previous: <span id="prev"></span></p>
<p>Current: <span id="curr"></span></p>
JS:
var selectElem = document.getElementById("mySelect");
var prev = document.getElementById("prev");
var curr = document.getElementById("curr");
var allEverSelected = [ selectElem.value ];
selectElem.addEventListener("change", function(evt){
allEverSelected.push( this.value );
prev.innerHTML = allEverSelected[allEverSelected.length - 2];
curr.innerHTML = allEverSelected[allEverSelected.length - 1];
});
To access default value, just get the <select> value after DOM loads.
selected attribute on <option> tag exist only to make other than first <option> element inside <select> default option, i.e.:
<select>
<option value="1">1</option>
<option selected value="2">2</option>
</select>
Above select's default value is 2.
I think this is the one what you want. Try it.
function onChangeOption(opt) {
var update_value = opt.value;
console.log(update_value);
var selectedValue;// = '???'; // get selected attribute
// I think this is the one you want
//If you want to select the HTML element,
selectedValue=document.querySelector("option[value='"+update_value+"']");
console.log(selectedValue);
//
if (update_value != selectedValue) {
// Do some things
}
}
//onChangeOption(document.querySelector('form'));
function start(){
while(typeof document.querySelector('form')!=typeof {}){}
onChangeOption(document.querySelector('.form-control'));
}
<body onload="start()">
<select class="form-control" onchange="onChangeOption(this)">
<option selected="selected" value="1">1</option>
<!-- I wanna got this -->
<option value="2">2</option>
</select></body>
My dropdown looks like,
<select name="speed" id="ddlCustomer" class="form-control select-basic">
<optgroup label="CustomerId OrderDate SupplyDate Supplier">
<option value="1011_2">1011 2015-12-18 2015-12-22 ABC</option>
<option value="1011_2">1034 2015-12-23 2015-12-28 XYZ</option>
</optgroup>
</select>
Currently the dropdown shows options like "1011 2015-12-18 2015-12-22 ABC", that is fine but when user selects an option, I need to show only "CustomerId" i.e, 1011 in this case.
Your help is really appreciated. Thanks
Added script for focusout
customSelect.focusout(function () {
customSelectOptions.each(function (options) {
if ($(this).is(':selected')) {
$(this).text($(this).attr('value').split('_')[0]);
$(this).blur();
}
});
});
var states = [];
var customSelect = $('#ddlCustomer');
var customSelectOptions = customSelect.children().children();
// Get each state then push them to the array
// Initial state declaration
customSelectOptions.each(function() {
var state = $(this).text();
states.push({ state: state });
if ($(this).is(':selected')) {
$(this).text($(this).attr('value').split('_')[0]);
}
});
// On focus, always retain the full state name
customSelect.on('focus', function() {
customSelectOptions.each(function(index) {
$(this).text(states[index].state);
});
// On change, append the value to the selected option
$(this).on('change', function() {
customSelectOptions.each(function(options) {
if ($(this).is(':selected')) {
$(this).text($(this).attr('value').split('_')[0]);
}
});
// Un-focus select on finish
$(this).blur();
});
});

<select name="speed" id="ddlCustomer" class="form-control select-basic">

<option value="1034_2">1034 2015-12-23 2015-12-28 XYZ</option>
</optgroup>
</select>
Try like this.You have use regex with text value of selected option.
var ddlCustomer = document.querySelector('#ddlCustomer');
ddlCustomer.addEventListener('change',function(){
text = $(this).find("option:selected").text();
var value = text.match(/[0-9]+/);
$(this).find("option:selected").text(value);
alert(value);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="speed" id="ddlCustomer" class="form-control select-basic">
<optgroup label="CustomerId OrderDate SupplyDate Supplier">
<option value="1011_2">1011 2015-12-18 2015-12-22 ABC</option>
<option value="1011_2">1034 2015-12-23 2015-12-28 XYZ</option>
</optgroup>
</select>
See fiddle here https://jsfiddle.net/88cozeaz/1/
document.getElementById('#ddlCustomer').onchange = function() {
var option = this.options[this.selectedIndex];
option.setAttribute('data-text', option.text);
option.text =$(this).val();
// Reset texts for all other but current
for (var i = this.options.length; i--; ) {
if (i == this.selectedIndex) continue;
var text = this.options[i].getAttribute('data-text');
if (text) this.options[i].text = text;
}
};

I have two types of optgroup with option.
I need to validate between two groups. How to do that ?
Case 1
If i select the A optgroup.simuultanseuly i cant able to select optgroup B
i need to select any one. can't select both at the same time.
Javascript
$('#select').change(function () {
var selectedOption = $('#select option:selected');
var label = selectedOption.closest('optgroup').attr('label');
var selectText = selectedOption.text();
if(label == 'A'){ $('.selectoption').val(label); }
var length = $(this).find(':selected').text().length;
$('')
if(label== 'A'){
alert('check');
} else {
alert('no test');
}
// if (length < 2) {
//$(this).find(':selected').text(label + ' - ' + selectText);
//}
});
You can use element.prop('disabled', boolean) to disable / enable the form elements.
You can disable the other optgroup using the above technique like this:
$(function(){
$('#select').change(function () {
$('optgroup').prop('disabled', false);
$('optgroup').removeClass('selected');
var selectedOption = $('#select option:selected');
$(".selectoption").val(selectedOption.closest('optgroup').attr('label'));
selectedOption.closest('optgroup').addClass('selected');
var label = selectedOption.closest('optgroup').attr('label');
var selectText = selectedOption.text();
$(this).find('optgroup').each(function(i) {
if(!$(this).hasClass('selected')) {
$(this).prop('disabled', true);
} else {
$(this).prop('disabled', false);
}
});
});
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="select" multiple style="height:150px;width:150px;">
<optgroup label="A">
<option value="">1</option>
<option value="">2</option>
<option value="">3</option>
</optgroup>
<optgroup label="B">
<option value="">4</option>
<option value="">5</option>
<option value="">6</option>
</optgroup>
</select>
<input type="text" name="selectoption" class="selectoption" value="" />
I have a list of users and each has a role.
The user who is selected as "Líder" can not have more than one role, only "Líder".
If the user selects another option (daughters) the option "Líder" should be disabled. Users who are not "Líder" can have more than one role.
Here is a simulation of the problem: jsfiddle
HTML:
<select class="selectpicker" id="funcao" multiple data-max-options="1">
<option value="lider">Líder</option>
<option value="conhecimento">Para Conhecimentor</option>
<option value="participante">Participante</option>
</select>
<br><br>
<select class="selectpicker" id="funcao" multiple data-max-options="1">
<option value="lider">Líder</option>
<option value="conhecimento">Para Conhecimentor</option>
<option value="participante">Participante</option>
</select>
<br><br>
<select class="selectpicker" id="funcao" multiple data-max-options="1">
<option value="lider">Líder</option>
<option value="conhecimento">Para Conhecimentor</option>
<option value="participante">Participante</option>
</select>
<br><br>
<select class="selectpicker" id="funcao" multiple data-max-options="1">
<option value="lider">Líder</option>
<option value="conhecimento">Para Conhecimentor</option>
<option value="participante">Participante</option>
</select>
JS:
$('select').change(function(){
var sel = $(this);
var data = sel.data('prev');
var val = sel.val();
var prev;
if(data){ prev = data.val; }
sel.data('prev', {val: val});
sel.nextAll().each(function(){
if(prev){
$(this).find("[value='" + prev+ "']").prop("disabled",false);
$('.selectpicker').selectpicker('refresh');
}
$(this).find("[value='" + val + "']").prop("disabled",true);
$('.selectpicker').selectpicker('refresh');
});
$('.selectpicker').selectpicker('refresh');
});
You can check the effect obtained with the code below - jsfiddle
$('select').change(function() {
var sel = $(this);
disableThis(sel);
$('.selectpicker').selectpicker('refresh');
});
function disableThis(sel) {
var temSelecionado = false;
$("option[value='1']").each(function() {
if (this.selected) {
temSelecionado = true;
$(this).parent().each(function() {
$(this.options).each(function() {
if ($(this).val() != "1") {
$(this).prop("disabled", true);
}
})
});
}
else {
$(this).parent().each(function() {
$(this.options).each(function() {
if ($(this).val() != "1") {
$(this).prop("disabled", false);
}
})
});
}
});
}
I have two select elements with times 12:00 AM through 11:45 PM,
both selects have the same options inside including text and value. Is it possible for example say I select 1:00 PM on the first select to remove all the options before 1:00 PM on the second select? I know I can detect the change with jquery
$('#select1').change(function(){
// in here do something to remove previous selects
});
Any help would be appreciated it.
Here is another version of the same where we allow for the user to change his first selection and still filter the second select correctly
$(document).ready(function() {
var to_mins = function(x) {
var p = x.split(':').map(function(v) { return parseInt(v, 10); });
return (p[0] * 60) + p[1];
};
$('#second').data('options', $('#second').find('option').toArray());
$('#first').change(function() {
var val = to_mins(this.value);
console.log(val);
$('#second').empty();
$('#second').data('options').filter(function(v) {
return to_mins(v.value) > val;
}).map(function(v) {
$('#second').append(v.cloneNode(true));
});
});
});
Try
$('#select1').change(function(){
var $this = $(this);
var index = $('option:selected', $this).index();
$('#select2 option').show().filter(':lt(' + index + ')').hide();
})
Demo: Fiddle
try this
$('#select1').change(function(){
var value = $(this).val();
$("#selectId > option").each(function() {
if(value > this.value)
$("#selectId option[value=this.value]").remove();
});
});
But the values need to be in ascending order for select boxes
HTML:
<select id="select1">
<option value="1">11h00</option>
<option value="2">11h15</option>
<option value="3">11h30</option>
<option value="4">11h45</option>
<option value="5">12h00</option>
<option value="6">12h15</option>
<option value="7">12h30</option>
<option value="8">12h45</option>
<option value="9">13h00</option>
</select>
<select id="select2">

<option value="2">11h15</option>
<option value="3">11h30</option>
<option value="4">11h45</option>
<option value="5">12h00</option>
<option value="6">12h15</option>
<option value="7">12h30</option>
<option value="8">12h45</option>
<option value="9">13h00</option>
</select>
JS:
$(document).ready( function(){
$('#select1').change(function(){
var val = $(this).find('option:selected').prop('value');
$('#select2').find('option').show().each(function(){
if( $(this).prop('value') <= val ){
$(this).hide();
}
else{
return false;
}
});
});
});
