I am making a system in which a user can change a select drop down and it will give them a prompt to ensure they want to take the action. Here is my code:
function changeResStatus(str1) {
var id = str1;
var status = document.getElementById("resstatus" + id).value;
var r = confirm("Change status for ID # " + id + " to " + status + "?");
if (r == true) {
console.log ("change made");
}else{
console.log ("change not made");
}
}
In the event the change is not made, I would like the select menu to go back to the previous option it was before the user attempted to change it. How would I do that?
please try this one.
$(document).on('change','.mydropdown',function(){
var previousValue = $(this).attr("data-previousvalue");
var r = confirm("Change status for");
if (r == true)
{
$(this).attr("data-previousvalue",$(this).val())
}
else
{
$(this).val($(this).attr("data-previousvalue"));
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select class="mydropdown" data-previousvalue="0">
<option value="0">select something</option>
<option value="1">something 1</option>
<option value="2">something 2</option>
<option value="3">something 3</option>
</select>
<select class="mydropdown" data-previousvalue="0">
<option value="0">select something</option>
<option value="101">something 101</option>
<option value="102">something 102</option>
<option value="103">something 103</option>
</select>
<select class="mydropdown" data-previousvalue="0">
<option value="0">select something</option>
<option value="201">something 201</option>
<option value="202">something 202</option>
<option value="202">something 203</option>
</select>

So this is the HTML code:
<select id='selUser' style='width: 200px;'>
<option value='0'>Select User</option>
<option value='1'>Yogesh singh</option>
<option value='2'>Sonarika Bhadoria</option>
<option value='3'>Anil Singh</option>
<option value='4'>Vishal Sahu</option>
<option value='5'>Mayank Patidar</option>
<option value='6'>Vijay Mourya</option>
<option value='7'>Rakesh sahu</option>
</select>
What I want to achieve is that, when I click on Value '1', the dropdownlist will display "1" instead of Yogesh Singh. Is it possible to do that?
This will display the value instead of the name when you select an option. I also wrote some code to put the name back if you change it again otherwise the number would just stay there added both examples:
var oldIndex = ''
var oldText = ''
function change(x) {
if (oldIndex != '' && oldText != '') {
x.options[oldIndex].innerHTML = oldText
}
oldIndex = x.value
oldText = x.options[x.selectedIndex].innerHTML
x.options[x.selectedIndex].innerHTML = x.value
}
function change2(x) {
x.options[x.selectedIndex].innerHTML = x.value
}
<select onchange="change(this)" id='selUser' style='width: 200px;'>
<option value='0'>Select User</option>
<option value='1'>Yogesh singh</option>
<option value='2'>Sonarika Bhadoria</option>
<option value='3'>Anil Singh</option>
<option value='4'>Vishal Sahu</option>
<option value='5'>Mayank Patidar</option>
<option value='6'>Vijay Mourya</option>
<option value='7'>Rakesh sahu</option>
</select>
<select onchange="change2(this)" id='selUser2' style='width: 200px;'>
<option value='0'>Select User</option>
<option value='1'>Yogesh singh</option>
<option value='2'>Sonarika Bhadoria</option>
<option value='3'>Anil Singh</option>
<option value='4'>Vishal Sahu</option>
<option value='5'>Mayank Patidar</option>
<option value='6'>Vijay Mourya</option>
<option value='7'>Rakesh sahu</option>
</select>
This script would do it:
document.body.onload = function(){
sel = document.getElementById('selUser');
opts = sel.childNodes;
for(var i in opts){
opts[i].innerHTML = opts[i].value;
}
}
Solution using jQuery:
var last_user_selected_name;
$(document).on('change', '#selUser', function() {
$('#selUser option:not(:selected)').each(function() {
if ($(this).text() === $(this).val()) {
$(this).text(last_user_selected_name);
}
});
var user_seleted = $('#selUser option:selected');
if (user_seleted.val() != 0) {
last_user_selected_name = user_seleted.text();
user_seleted.text(user_seleted.val());
console.log("User selected >> " + last_user_selected_name +
" >> " + user_seleted.val());
}
});
<script src='https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js'></script>
<select id='selUser' style='width: 200px;'>
<option value='0'>Select User</option>
<option value='1'>Yogesh singh</option>
<option value='2'>Sonarika Bhadoria</option>
<option value='3'>Anil Singh</option>
<option value='4'>Vishal Sahu</option>
<option value='5'>Mayank Patidar</option>
<option value='6'>Vijay Mourya</option>
<option value='7'>Rakesh sahu</option>
</select>
The options in my "States" drop-down menu are all being hidden
I'm trying to filter based on the value of the Country drop-down which is selected.
$('#Content_C003_Country').change(function() {
const filter = $(this).val();
//console.log(filter);
$("#Content_C003_State option").each(function() {
($("option[value^='" + filter + "']") != -1) ? $(this).hide(): $(this).show();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<select id="Content_C003_Country" class="searchFieldDrop">
<option value="36">Canada</option>
<option value="222">United States</option>
</select>
<select id="Content_C003_State" class="searchFieldDrop">
<option value="36-AB">Alberta</option>
<option value="36-BC">British Columbia</option>
<option value="36-MB">Manitoba</option>
<option value="222-AZ">Arizona</option>
<option value="222-AR">Arkansas</option>
<option value="222-CA">California</option>
</select>
(function($){
var $country = $('#Content_C003_Country');
var $state = $('#Content_C003_State');
var $stateOptions = $state.children();
$country.on('change', function(){
//remove the options
$stateOptions.detach();
//readd only the options for the country
$stateOptions.filter(function(){
return this.value.indexOf($country.val() + "-") === 0;
}).appendTo($state);
//clear out the value so it doesn't default to one it should not
$state.val('');
});
}(jQuery));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="Content_C003_Country" class="searchFieldDrop">
<option value="36">Canada</option>
<option value="222">United States</option>
</select>
<select id="Content_C003_State" class="searchFieldDrop">
<option value="36-AB">Alberta</option>
<option value="36-BC">British Columbia</option>

<option value="222-AZ">Arizona</option>
<option value="222-AR">Arkansas</option>
<option value="222-CA">California</option>
</select>
That could be achieved simply like :
$('#Content_C003_Country').change(function() {
//Hide all options
$("#Content_C003_State option").hide();
//Show the filtred ones
$("#Content_C003_State option[value^='" + $(this).val() + "']").show();
});
Or also using one line like :
$("#Content_C003_State option").hide().end().find('[value^='+$(this).val()+']').show();
Code:
$('#Content_C003_Country').change(function() {
$("#Content_C003_State option").hide();
$("#Content_C003_State option[value^='" + $(this).val() + "']").show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<select id="Content_C003_Country" class="searchFieldDrop">
<option value="36">Canada</option>
<option value="222">United States</option>
</select>
<select id="Content_C003_State" class="searchFieldDrop">
<option value="36-AB">Alberta</option>
<option value="36-BC">British Columbia</option>
<option value="36-MB">Manitoba</option>
<option value="222-AZ">Arizona</option>
<option value="222-AR">Arkansas</option>
<option value="222-CA">California</option>

I have 3 drop downs, but it can change. It is dynamic drop down
How can I get all selected values in those drop downs?
This is an explanation of my comment..
Run the snippet to check it in action
var combos = document.querySelectorAll('[name^="select"]');
function getvalues() {
// Clear shown data
console.clear();
for (var i=0; i < combos.length; i++) {
// Get selected option value
var option = combos[i].options[combos[i].selectedIndex];
// Show options
console.log(combos[i].name + " :: " + option.value + " : " + option.text);
}
}
<select name="select-1">
<option value="1" selected>First</option>
<option value="2">Second</option>
<option value="3">Third</option>
</select>
<select name="select-2">
<option value="1">First</option>
<option value="2" selected>Second</option>
<option value="3">Third</option>
</select>
<select name="select-3">
<option value="1">First</option>
<option value="2">Second</option>
<option value="3" selected>Third</option>
</select>
<button onclick="getvalues()">Get values</button>
i am new to Javascript/ Jquery
so my problem is :
i want to change the select/option box text and value depending on the other selected option/box
so for examplemy first option is :
<select id="gender">
<option>Select Your Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
and then one i want to change depending on selected option is :
When its male :
<select id="name">
<option>Select Your Name</option>
<option value="Male1">Male 1</option>
<option value="Male2">Male 2</option>
</select>
when its female :
<select id="name">
<option>Select Your Name</option>
<option value="female1">Female 1</option>
<option value="female2">Female 2</option>
</select>
Thanks for the help! :)
There you go with DEMO
var options=""; //store the dynamic options
$("#gender").on('change',function(){ //add a change event handler to gender select
var value=$(this).val(); //get its selected value
options="<option>Select Your Name</option>"
if(value=="Male") //value ==Male then set male required options
{
options+="<option value='Male1'>Male 1</option>"
+"<option value='Male2'>Male 2</option>";
$("#name").html(options);
}
else if(value=="Female") //else set female required options
{
options+='<option value="female1">Female 1</option>'
+'<option value="female2">Female 2</option>';
$("#name").html(options);
}
else
$("#name").find('option').remove() //if first default text option is selected empty the select
});
I would suggest to have a better HTML architecture to achieve this kind of things. Have each name in one Dropdown only and categorise with some data attribute. When changing the value of Gender Dropdown, filter with type and toggle the options. Follow this:
$(function(){
$("#gender").on("change", function(){
var $target = $("#name").val(""),
gender = $(this).val();
$target
.toggleClass("hidden", gender === "")
.find("option:gt(0)").addClass("hidden")
.siblings().filter("[data-type="+gender+"]").removeClass("hidden");
});
});
.hidden{
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select id="gender">
<option value="">Select Your Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
<select id="name" class="hidden">
<option value="">Select Your Name</option>
<option value="Male1" data-type="Male">Male 1</option>
<option value="Male2" data-type="Male">Male 2</option>
<option value="female1" data-type="Female">Female 1</option>
<option value="female2" data-type="Female">Female 2</option>
</select>
Fiddle link: http://jsfiddle.net/ashishanexpert/qzxedcut/
Whenever a change occurs, use the value of the gender dropdown to populate the names one. We use a for loop to produce more than one option per gender.
$('#gender').change(function(){
if(!this.selectedIndex) return;
var gender = $(this).val(),
$name = $('#name').empty(),
$option = $('<option />').text('Select Your Name').appendTo($name);
for(var i = 1; i <= 2; i++)
$option.clone().prop('value', gender + i).text(gender + ' ' + i).appendTo($name);
});
JSFiddle
Follow the Practice:
Do not hardcode options this case.Best practice is get value from Json.
Then later changes are easy instead of change all codings.
Build dynamic Dropdowns. Dont Hide and Show.
HTML
<select id="gender">
<option>Select Your Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
<select id="gtr" name="location" placeholder="Anycity"></select>
Jquery
jQuery(function($) {
var gender = {
'Male': ['Male1', 'male2'],
'Female': ['Female1','Female1'],
}
var $gndr = $('#gtr');
$('#gender').change(function () { debugger
var GNDR = $(this).val(), gndrs = gender[GNDR] || [];
var html = $.map(gndrs, function(gndr){
return '<option value="' + gndr + '">' + gndr + '</option>'
}).join('');
$gndr.html(html);$gndr.append(new Option("Select Name", "0"));$gndr.val("0");
});
});

I suggest you to try this way:
Change you jquery:
<select id="nameMale">
<option>Select Your Name</option>
<option value="Male1">Male 1</option>
<option value="Male2">Male 2</option>
</select>
<select id="nameFemale">
<option>Select Your Name</option>
<option value="Male1">Male 1</option>
<option value="Male2">Male 2</option>
</select>
Inser this javascript:
<script>
<![CDATA[
$(function() {
$('#nameFemale').hide();
$('#nameMale').hide();
function changeGen(val){
if(val == 'Female'){
$('#nameFemale').show();
$('#nameMale').hide();
}else{
$('#nameFemale').hide();
$('#nameMale').show();
}
}
$('#gender').change(function() {
changeGen($('#gender').val());
});
});
]]>
</script>
FIDDLE
$('#gender').change(function (e) {
var val = $("option:selected", this).val()
console.log(val);
if(val =='Male'){
$('#name').find('option.female').hide();
$('#name').find('option.male').show();
}else if(val =='Female'){
$('#name').find('option.female').show();
$('#name').find('option.male').hide();
}else{
}
});
Added class for each option since it is static.
Then you can hide the option from second select depending on the value of first select
Try this:
$("#gender").on("change",function(){
var sel="";
if($(this).val() == "Female"){
sel=' <option>Select Your Name</option>';
sel+=' <option value="female1">Female 1</option>'
sel+='<option value="female2">Female 2</option>'
}else{// no other if since you have only two options male/female
sel= '<option>Select Your Name</option>';
sel+= '<option value="Male1">Male 1</option>';
sel+= '<option value="Male2">Male 2</option>';
}
$("#name").html(sel);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="gender">
<option>Select Your Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
<select id="name">
</select>
Say I have this dropdown:
<select id="theOptions1">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
I want it so that when the user selects 1, this is the thing that the user can choose for dropdown 2:
<select id="theOptions2">
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
</select>
Or if the user selects 2:
<select id="theOptions2">
<option value="a">a</option>
<option value="b">b</option>
</select>
Or if the user selects 3:
<select id="theOptions2">
<option value="b">b</option>
<option value="c">c</option>
</select>
I tried the code posted here:
jQuery disable SELECT options based on Radio selected (Need support for all browsers)
But it doesn't work for selects.
Please help!
Thank you!
UPDATE:
I really like the answer Paolo Bergantino had on:
jQuery disable SELECT options based on Radio selected (Need support for all browsers)
Is there anyway to modify this to work with selects instead of radio buttons?
jQuery.fn.filterOn = function(radio, values) {
return this.each(function() {
var select = this;
var options = [];
$(select).find('option').each(function() {
options.push({value: $(this).val(), text: $(this).text()});
});
$(select).data('options', options);
$(radio).click(function() {
var options = $(select).empty().data('options');
var haystack = values[$(this).attr('id')];
$.each(options, function(i) {
var option = options[i];
if($.inArray(option.value, haystack) !== -1) {
$(select).append(
$('<option>').text(option.text).val(option.value)
);
}
});
});
});
};
This works (tested in Safari 4.0.1, FF 3.0.13):
$(document).ready(function() {
//copy the second select, so we can easily reset it
var selectClone = $('#theOptions2').clone();
$('#theOptions1').change(function() {
var val = parseInt($(this).val());
//reset the second select on each change
$('#theOptions2').html(selectClone.html())
switch(val) {
//if 2 is selected remove C
case 2 : $('#theOptions2').find('option:contains(c)').remove();break;
//if 3 is selected remove A
case 3 : $('#theOptions2').find('option:contains(a)').remove();break;
}
});
});
And the beautiful UI:
<select id="theOptions1">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<br />
<select id="theOptions2">
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
</select>
You can add classes to your <option>s to store which go with each value of #theOptions1:
<select id="theOptions2">
<option value="a" class="option-1 option-2">a</option>
<option value="b" class="option-1 option-2 option-3">b</option>
<option value="c" class="option-1 option-3">c</option>
</select>
then do this:
$(function() {
var allOptions = $('#theOptions2 option').clone();
$('#theOptions1').change(function() {
var val = $(this).val();
$('#theOptions2').html(allOptions.filter('.option-' + val));
});
});
For the record you can NOT remove options in a select list in Internet Explorer.
try this. this will definitely work
$(document).ready(function () {
var oldValue;
var oldText;
var className = '.ddl';
$(className)
.focus(function () {
oldValue = this.value;
oldText = $(this).find('option:selected').text();
})
.change(function () {
var newSelectedValue = $(this).val();
if (newSelectedValue != "") {
$('.ddl').not(this).find('option[value="' + newSelectedValue + '"]').remove();
}
if ($(className).not(this).find('option[value="' + oldValue + '"]').length == 0) { // NOT EXIST
$(className).not(this).append('<option value=' + oldValue + '>' + oldText + '</option>');
}
$(this).blur();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<form action="/Home/Ex2" method="post">
<select class="ddl" id="A1" name="A1">
<option value="">Select</option>
<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>
<option value="4">D</option>
</select>
<hr />
<select class="ddl" id="A2" name="A2">
<option value="">Select</option>
<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>
<option value="4">D</option>
</select>
<hr />
<select class="ddl" id="A3" name="A3">
<option value="">Select</option>
<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>
<option value="4">D</option>
</select>
<hr />
<select class="ddl" id="A4" name="A4">
<option value="">Select</option>
<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>
<option value="4">D</option>
</select>
<hr />
<input type="submit" name="submit" value="Save Data" id="btnSubmit" />
</form>
Actually, using the code below will remove a dropdown option just fine in IE, as long as it is not the selected option (it will not work on "a" without deselecting that option first):
var dropDownField = $('#theOptions2');
dropDownField.children('option:contains("b")').remove();
You just run this to remove whatever option you want to remove under a conditional statement with the first group (theOptions1) - that if one of those is selected, you run these lines:
var dropDownField = $('#theOptions2');
if ($('#theOptions1').val() == "2") {
dropDownField.children('option:contains("c")').remove();
}
if ($('#theOptions1').val() == "3") {
$("#theOptions2 :selected").removeAttr("selected");
$('#theOptions2').val('b');
dropDownField.children('option:contains("a")').remove();
}
