I have many filter button like below, how can I get the select value without using its id?
<select name="selectId" id="selectId" multiple
class="selectpicker required form-control" data-live-search="true">
<option value="All" selected>All</option>
<option value="1" selected>1</option>
<option value="2" selected>2</option>
</select>
<select name="selectStore" id="selectStore" multiple
class="selectpicker required form-control" data-live-search="true">
<option value="All" selected>All</option>
<option value="A" selected>Store A</option>
<option value="B" selected>Store B</option>
</select>
<select name="selectProduct" id="selectProduct" multiple
class="selectpicker required form-control" data-live-search="true">
<option value="All" selected>All</option>
<option value="apple" selected>Apple</option>
<option value="orange" selected>Orange</option>
</select>
Normally, I will use this code to find the changed select button:
$(document).ready(function() {
// Get filter function for chart
$('#selectId').change(function() {
var select = $("#selectId").val();
if (selectLength >= 1 && select.includes("All")) {
$('.selectpicker#selectId').selectpicker('deselectAll');
makeChart();
}
else {
makeChartFilter(select);
}
})
});
But the problem is when there are many filter buttons, I have to write many functions like above and just only change the id.
How can I just use something like this:
$(document).ready(function() {
// Get filter function for chart
$('#selectpicker').change(function() {
id_change = something;
var select = $("#id_change").val();
...
})
});
Using vanilla JavaScript and the eventTarget, this is relatively straight forward. Here is an example:
document.getElementById('container').onchange = ({ target }) => {
console.log(target.value);
};
<form id="container">
<select name="foo">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
<select name="bar">
<option>a</option>
<option>b</option>
<option>c</option>
</select>
</form>

I have 4 choice fields in a single form. My jQuery code only captures one field. How can I capture the other fields and extract their values?
Also, I have applied the Select2 plugin on all these fields. Can someone please guide me? Thanks in advance.
$('select').change(function() {
var optionSelected = $(this).find("option:selected");
var valueSelected = optionSelected.val();
var textSelected = optionSelected.text();
var csr = $("input[name=csrfmiddlewaretoken]").val();
console.log(textSelected);
});

To get the selected text of all the select elements you can use map() to build an array of them, like this:
let getSelectedText = () => {
let textArr = $selects.map((i, el) => $(el).find('option:selected').text()).get();
console.log(textArr);
}
let $selects = $('select').on('change', getSelectedText);

I have 2 select boxes where first is all user selectable but in second selected option is dependant on first select box. Selected value in first option box matches option's class in second select box but values are different. I imagine i need something like:
$('#territory').change(function() {
if($(this).val() == 'EU')
{
$('#territory2').class('EU');
}
How do i select selected option by class name? (There might be more than 1 option with the same class name but it just needs to select any of them).
<select id="territory" name="territory"">
<option value="EU">A</option>
<option value="GB">B</option>
<option value="ALL">C</option>
</select>
<select id="territory2" name="territory2">
<option value="1" class="EU">A</option>
<option value="2" class="GB">B</option>
<option value="3" class="ALL">C</option>
<option value="4" class="ALL">D</option>
</select>
Set the value attribute of the desired <option> element on the value attribute of the <select>:
const territory = document.getElementById("territory"),
territory2 = document.getElementById("territory2");
territory.addEventListener("input", ev => {
territory2.querySelector("."+territory.value).selected = true;
});
<select id="territory" name="territory">
<option value="EU">A</option>
<option value="GB">B</option>
<option value="ALL">C</option>
</select>
<select id="territory2" name="territory2">
<option value="1" class="EU">A</option>
<option value="2" class="GB">B</option>
<option value="3" class="ALL">C</option>
<option value="4" class="ALL">D</option>
</select>
Note that this will only select the first option with that class.
I recommend data-attribute:
$('#territory').on("change", function() {
const territory = $("option:selected", this).data("territory");
$("#territory2").val(territory)
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="territory" name="territory">
<option value="" data-territory="0">Please select</option>
<option value="EU" data-territory="1">A</option>
<option value="GB" data-territory="2">B</option>
<option value="ALL" data-territory="3">C</option>
</select>
<select id="territory2" name="territory2">
<option value="0">Please select</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
I'm trying to understand why when I select <select> and targeting any option
it return select-one . why -one? can it be in some cases counting more or sth else so naming convention have a useful meaning ?
in the code below I'm comparing between input and select maybe they'r not relevant but looks interesting.
$('input[type="checkbox"],input[type="radio"]').on("change",function(event){
console.log(event.target.type);
});
$('#foo,#foo2').on("change",function(event){
console.log(event.target.type);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" name="select">
<input type="radio" name="select">
<select id="foo">
<option value="1">Value1</option>
<option value="2">Value2</option>
</select>
<select id="foo2">
<option value="1">Value1</option>
<option value="2">Value2</option>
</select>
It's to distinguish from the case of when you add the multiple optional attribute to the select. It will then return select-multiple.
multiple
This Boolean attribute indicates that multiple options can be selected in the list. If it is not specified, then only one option can
be selected at a time. When multiple is specified, most browsers will
show a scrolling list box instead of a single line dropdown

I need your help. So what I want to do is when a user select an option from one select, automatically hide an option from another multiple select.
Example:
if a user choose Car from select A, I want the car option from the select B to be automatically removed or hidden.
select A:
<select name="my_option_one" required id="id_my_option_one">
<option value="" selected>Choose..</option>
<option value="C">Car</option>
<option value="H">House</option>
<option value="A">Airplane</option>
</select>
Select B:
<select name="my_option_two" id="id_my_option_two" multiple="multiple">
<option value="C">Car</option>
<option value="H">House</option>
<option value="A">Airplane</option>
</select>
This is what I have tried but none of it worked.
$(document).ready(function() {
$("#id_my_option_one").change(function() {
if ($(this).val() === 'C') {
$("#id_my_option_two option[value='C']").options[0].remove();
$('select[name=my_option_two] option:eq(1)').hide();
$("#id_my_option_two option[value=" + 'C' + "]").hide();
$("#id_my_option_two option[value='C']").attr('disabled','disabled').hide();
}
});
});
function my_optionsChange() {
$("#id_my_options_two option").show(); //.css("display", "block");
$("#id_my_options_two option[value='" + $("#id_my_options").val() + "']").hide();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<select name="my_options" required id="id_my_options" onchange="my_optionsChange()">
<option value="" selected>Choose..</option>
<option value="C">Car</option>
<option value="H">House</option>
<option value="A">Airplane</option>
</select>
<select name="my_options_two" id="id_my_options_two" multiple="multiple">
<option value="C">Car</option>
<option value="H">House</option>
<option value="A">Airplane</option>
</select>
I made an example which is longer because it's split into parts so you understand better what is going on.
I tried to name the variables so that it's clear what they are, but if you have any questions, please ask in the comments.
Let me know if this works for you.
const firstSelect = $('#id_my_options')
const secondSelect = $('#id_my_options_two')
firstSelect.on('change',function() {
const selected = $(this).find('option:selected');
const selectedValue = selected.val()
const secondOptions = secondSelect.children();
secondOptions.each(function() {
const secondValue = $(this).val()
secondValue === selectedValue ? $(this).hide() : $(this).show()
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="my_options" required id="id_my_options">
<option value="Choose" selected>Choose..</option>
<option value="C">Car</option>

</select>
<select name="my_options_two" id="id_my_options_two" multiple="multiple">
<option value="C">Car</option>
<option value="H">House</option>
<option value="A">Airplane</option>
</select>
<select name="my_options" id="firstblock" onchange="disable(2,this.value);">
<option value="" selected>Choose..</option>
<option value="C">Car</option>
<option value="H">House</option>
<option value="A">Airplane</option>
</select>
<select name="my_options" id="secondblock" onchange="disable(1,this.value);">
<option value="" selected>Choose..</option>
<option value="C">Car</option>
<option value="H">House</option>
<option value="A">Airplane</option>
</select>
<script>
function disable(needtoblock,val){
console.log(needtoblock+" "+val);
if(val != ""){
if(needtoblock == 1){
$("#firstblock option[value='"+val+"']").prop('disabled', true);
}else if(needtoblock == 2){
$("#secondblock option[value='"+val+"']").prop('disabled', true);
}else{
}
}else{
$("#secondblock option").prop('disabled', false);
$("#firstblock option").prop('disabled', false);
}
}
</script>
This is how code could look, definetly you need to update and make it suitable for you.
I know, this is a bit late, but maybe it is of interest to someone out there. I understood the demand of OP so, that the hiding of options was to be done in any direction, or potentially spanning over multiple selector boxes. The following script will do exactly that: if you select an option in one selector it will go through the other selectors of the defined group $grp (by doing $grp.not(this).each((i,trg)=> ...)) and will hide/show all options there, depending of whether thay have been selected elsewhere already.
The $(to).toggle(...) method sets the visibility of each option (to) within trg, based on the existence of selected options with the same value in the sibling selectors of trg (again, limited to the current group $grp).
Maybe the script is a little too condensed for easy reading but it shows how much you can achieve with very little code when you use the power of jQuery.
const $grp=$('select[id^=id_my_options]') // define the selector group
$grp.on('change',function(ev){ // bind the change event ...
$grp.not(this).each((i,trg)=> // work on each sibling-selector (trg) of clicked
// selector (this), but only within jquery
// selection $grp
$('option[value!=""]',trg).each((j,to)=> // for all options of sibling-selectors of
// trg (within jquery selection $grp):
$(to).toggle($grp.not(trg).find('option[value='+to.value+']:selected').length==0))
// toggle the visibiltiy of that option
)
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="my_options" required id="id_my_options">

I have 2 drop down list
<select id="servergroup" multiple="multiple">
<option value="P1">P1</option>
<option value="P2">P2</option>
<option value="P3">P3</option>
<option value="P4">P4</option>
</select>
<select id="servername" multiple="multiple">
<option value="s597ap233">s597ap233</option>
<option value="s597dp392">s597dp392</option>
<option value="s397dp095">s397dp095</option>
</select>
I want that the second drop down list should get enabled only if we choose a value in the first drop down list. It should again get disabled if we deselect the value from the first drop down list.
May I know how can this be achieved using jQuery?
You can use the disabled attribute and using JavaScript, you can set it as false or true
function check(){
if(document.getElementById('servergroup').value!='')
document.getElementById('servername').disabled=false;
else
document.getElementById('servername').disabled=true;
}
<select onchange="check()" id="servergroup" multiple="multiple">
<option value="P1">P1</option>
<option value="P2">P2</option>
<option value="P3">P3</option>
<option value="P4">P4</option>
</select>
<select disabled id="servername" multiple="multiple">
<option value="s597ap233">s597ap233</option>
<option value="s597dp392">s597dp392</option>
<option value="s397dp095">s397dp095</option>
</select>
$('#bonusVoucher').prop('disabled',false);
jQuery('#bonusVoucher').selectpicker('refresh');
Use selectpicker like this and the most IMPORTANT part is this:
Note: Place your bootsrap selectpicker script after jquery script.

jQuery solution.
function change() {
if ($('#servergroup option:selected').length) {
$('#servername').attr('disabled', false);
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="servergroup" multiple="multiple" onchange='change()'>
<option value="P1">P1</option>
<option value="P2">P2</option>
<option value="P3">P3</option>
<option value="P4">P4</option>
</select>
<select id="servername" multiple="multiple" disabled>
<option value="s597ap233">s597ap233</option>
<option value="s597dp392">s597dp392</option>
<option value="s397dp095">s397dp095</option>
</select>
First add
<option value="-1"> -Select Server Group- </option>
and
<option value="-1"> -Select Server Name- </option>
to Your Dropdown boxes respectively.
We can achieve requested actions using JQuery as Follows:
$(document).ready(function ()
{
//making serverName Dropdown box disabled by default.
$('#servername').prop('disabled', true);
$('#servergroup').change(function ()
{
if($(this).val == "-1")
{
$('#servername').val = "-1";
$('#servername').prop('disabled', true);
}
else
{
$('#servername').prop('disabled', false);
}
});
});
