I have searching the web for a while and still I cant find an answer, I have three drop-down menus on my site.
I use them for accepting user preferences so the user can control the output of results.
So I want to know if its possible for the value to be taken out of the other 2 dropdowns if its selected in one.
for example if the user selects movies in the first one it wont be in the others.
here is my dropdowns
<select id="pref1select">
<option value="P">Preference One</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
<select id="pref2select">
<option value="P">Preference Two</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
<select id="pref3select">
<option value="P">Preference Three</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
This will disable it, but not remove it.
Fiddle: http://jsfiddle.net/p2SFA/1/
HTML: (Added .preferenceSelect class) and jQuery:
$(document).ready(function() {
$(".preferenceSelect").change(function() {
// Get the selected value
var selected = $("option:selected", $(this)).val();
// Get the ID of this element
var thisID = $(this).prop("id");
// Reset so all values are showing:
$(".preferenceSelect option").each(function() {
$(this).prop("disabled", false);
});
$(".preferenceSelect").each(function() {
if ($(this).prop("id") != thisID) {
$("option[value='" + selected + "']", $(this)).prop("disabled", true);
}
});
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<select id="pref1select" class="preferenceSelect">
<option value="P">Preference One</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
<select id="pref2select" class="preferenceSelect">
<option value="P">Preference Two</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
<select id="pref3select" class="preferenceSelect">
<option value="P">Preference Three</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
If you want it removed, you will probably have to make jQuery know what to insert when it has reset because a new choice is made :)
This should work for you:
$(document).ready(function() {
$(".preferenceSelect").change(function() {
// Get the selected value
var selected = $("option:selected", $(this)).val();
// Get the ID of this element
var thisID = $(this).attr("id");
// Reset so all values are showing:
$(".preferenceSelect option").each(function() {
$(this).show();
});
$(".preferenceSelect").each(function() {
if ($(this).attr("id") != thisID) {
$("option[value='" + selected + "']", $(this)).hide();
}
});
});
});`
You should try this:
$(".preferenceSelect").on("change", function () {
$(".preferenceSelect option").prop("disabled", false);
var selectPref = $("option:selected", $(this)).val();
var selectId = $(this).prop("id");
$(".preferenceSelect option").each(function () {
$(this).show();
});
$(".preferenceSelect").each(function () {
if ($(this).prop("id") != selectId) {
$("option[value='" + selectPref + "']", $(this)).prop("disabled", true);
}
});
});
This must be work for you.
I believe something like this would do the trick given the HTML above:
var $selects = $("select");
$selects.on("change", function(){
var value = this.value;
$("option[value='" + value +"']", $selects).prop("disabled", true);
});
var $selects = $("select");
$selects.on("change", function(){
var value = this.value;
$("option[value='" + value +"']", $selects).prop("disabled", true);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select id="pref1select">
<option value="P">Preference One</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
<select id="pref2select">
<option value="P">Preference Two</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
<select id="pref3select">
<option value="P">Preference Three</option>
<option value="M">Movie</option>
<option value="T">Tv</option>
<option value="G">Games</option>
</select>
This disables the duplicate options, but it's an easy change to remove them as well. You'll run into a slight issue, though, since the "Preference #" options all have the same value. I would recommend either making these optgroup labels or removing the values entirely and marking them as disabled from the start...since you shouldn't be able to click them in the first place. You can find a bit more on option labels, and separators answered here.
Example
Please try the following which is working fine with no issue. I am also marking the selected option as disable instead of hiding from the other dropdowns.
$( function() {
courC();
});
function courC(){
var previous;
$(".pSel").on('focus', function () {
previous = this.value;
}).change(function() {
var selected = $("option:selected", $(this)).val();
var thisID = $(this).attr("id");
$(".pSel option").each(function() {
$(this).show();
});
$(".pSel").each(function() {
var otid=$(this).attr("id");
if (otid != thisID) {
if( $('#'+otid).val() == selected){ $('#'+otid).val(''); } // this is required when you are viewing data once again after the form submission
$("option[value='" + selected + "']", $(this)).attr("disabled", true);
}
$("option[value='" + previous + "']", $(this) ).attr("disabled", false); // this will help to reset the previously selected option from all dropdown
});
previous = $('#'+thisID).val();
});
}

I require a bit of jQuery to do the following:
A user can currently select Program and/or a region.
If a user selects Program AND a Region I require the option values of the region dropdown to change to "?region=1" and "?region=2"
<select class="program" id="program">
<option value="program1.html">Program 1</option>
<option value="program2.html">Program 2</option>
</select>
<select class="region" id="region">
<option value="region1.html">Region 1</option>
<option value="region2.html">Region2</option>
</select>
Greatly appreciate the assist.
My attempt at JQuery:
$('#program').on('change', function () { if($(this).val() !="0") { } else { // no option is selected } })
You need to further extend the change event for #program and include a similar one for #region.
var programSelected = null;
var regionSelected = null;
$('#program').on('change', function(element) {
programSelected = $('#program option:selected').text();
updateRegionOptions();
});
$('#region').on('change', function(element) {
regionSelected = $('#region option:selected').text();
updateRegionOptions();
});
function updateRegionOptions() {
if(programSelected != null && regionSelected != null) {
$('#region option').each(function() {
var modifiedString = '?';
modifiedString += $(this).val().replace(/\d+/,'');
modifiedString = modifiedString.replace('.html','');
modifiedString += '=';
modifiedString += $(this).val().match(/\d+/);
$(this).val(modifiedString);
});
}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select class="program" id="program">
<option value="" selected disabled>Select Program</option>
<option value="program1.html">Program 1</option>
<option value="program2.html">Program 2</option>
</select>
<select class="region" id="region">
<option value="" selected disabled>Select Region</option>
<option value="region1.html">Region 1</option>
<option value="region2.html">Region2</option>
</select>
Explanation of the logic above:
on('change' event for both #region and #program
Set the relevant variable programSelected or regionSelected depending on the change event
Run function updateRegionOptions();
If the variables programSelected and regionSelected both have a value
For each of the options in #region
Mutate the existing value to be of the form "?region=1" and "?region=2"
Update the value section of each of the option elements to have this value
The relevant JSFiddle for review.
If this solved your issue, please accept this answer :)
I have two dropdowns, both have the same items in them. If an option is selected in dropdown 1 then I would like to hide that option in dropdown 2. When it is unselected in dropdown 1 I would like it to appear again in dropdown 2 and whichever option is then selected to then be hidden in dropdown 2. I am trying to have this exclude the blank option in the first index.
Here is a codepen that I started, but I am not sure where to go from here:
http://codepen.io/cavanflynn/pen/EjreJK
var $dropdown1 = $("select[name='dropdown1']");
var $dropdown2 = $("select[name='dropdown2']");
$dropdown1.change(function () {
var selectedItem = $($dropdown1).find("option:selected").val;
});
Thanks for your help!
As said in comments, one of the options is to disable/enable options according to the selection in the first select, like below. This would work on all browsers as opposed to hide/show which doesn't.
var $dropdown1 = $("select[name='dropdown1']");
var $dropdown2 = $("select[name='dropdown2']");
$dropdown1.change(function() {
$dropdown2.find('option').prop("disabled", false);
var selectedItem = $(this).val();
if (selectedItem) {
$dropdown2.find('option[value="' + selectedItem + '"]').prop("disabled", true);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="dropdown1">
<option></option>
<option value="1">Test 1</option>
<option value="2">Test 2</option>
<option value="3">Test 3</option>
</select>
<select name="dropdown2">
<option></option>
<option value="1">Test 1</option>
<option value="2">Test 2</option>
<option value="3">Test 3</option>
</select>
Another option is to remove/add options in the 2nd dropdown based on the selection in the first via .clone(), as below.
var $dropdown1 = $("select[name='dropdown1']");
var $dropdown2 = $("select[name='dropdown2']");
$dropdown1.change(function() {
$dropdown2.empty().append($dropdown1.find('option').clone());
var selectedItem = $(this).val();
if (selectedItem) {
$dropdown2.find('option[value="' + selectedItem + '"]').remove();
}
});
A Demo
var $dropdown1 = $("select[name='dropdown1']");
var $dropdown2 = $("select[name='dropdown2']");
$dropdown1.change(function() {
var selectedItem = $(this).val();
var $options = $("select[name='dropdown1'] > option").clone();
$("select[name='dropdown2']").html($options);
$("select[name='dropdown2'] > option[value="+selectedItem+"]").remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select name="dropdown1">
<option></option>
<option value="1">Test 1</option>
<option value="2">Test 2</option>
<option value="3">Test 3</option>
</select>
<select name="dropdown2">
<option></option>
<option value="1">Test 1</option>
<option value="2">Test 2</option>
<option value="3">Test 3</option>
</select>
Demo
You should use this plugin http://gregfranko.com/jquery.selectBoxIt.js
It has some really nice callbacks and customisation options.
When one changes you can put it in the callback to update the other.
Here is one way of doing it. You do need to include jQuery, and then as long as the value isn't empty hide the option with the similar value.
var $dropdown1 = $("select[name='dropdown1']");
var $dropdown2 = $("select[name='dropdown2']");
$dropdown1.change(function() {
$dropdown2.children().show();
var selectedItem = $($dropdown1).val();
if (selectedItem != "")
$('select[name="dropdown2"] option[value="' + selectedItem + '"]').hide();
});
$dropdown2.change(function() {
$dropdown1.children().show();
var selectedItem = $($dropdown2).val();
if (selectedItem != "")
$('select[name="dropdown1"] option[value="' + selectedItem + '"]').hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="dropdown1">
<option></option>
<option value="1">Test 1</option>
<option value="2">Test 2</option>
<option value="3">Test 3</option>
</select>
<select name="dropdown2">
<option></option>
<option value="1">Test 1</option>
<option value="2">Test 2</option>
<option value="3">Test 3</option>
</select>
Here's an approach that stores a set of the options on page load then filters the alternate select when a change is made. It works in both directions for changes made to either select
var $drops = $('.drop'),
// store a set of options
$options = $drops.eq(1).children().clone();
$drops.change(function(){
var $other = $drops.not(this),
otherVal = $other.val(),
newVal = $(this).val(),
$opts = $options.clone().filter(function(){
return this.value !== newVal;
})
$other.html($opts).val(otherVal);
});
Values will also be maintained and this is 2 directional so a change in either will filter the other

Well, this code will find option by value in necessary selects and remove it.
http://codepen.io/anon/pen/LVqgbO
var $dropdown1 = $("select[name='dropdown1']");
var $dropdown2 = $("select[name='dropdown2']");
var populateDropdown = function(element) {
element.find("option").remove();
element.append("<option></option>");
// There should be real data
for (var i = 1; i <= 3; i++) {
element.append("<option value='" + i + "'>Test " + i + "</option>");
}
}
var getOptionProps = function(element) {
var selectedValue = element.val();
var selectedText = element.find("option[value=" + selectedValue + "]").text();
return { text: selectedText, value: selectedValue };
}
var removeOptionWithValue = function(element, value) {
element.find("option[value='" + value + "']").remove();
}
$dropdown1.on("change", function () {
var selectedProps = getOptionProps($(this));
populateDropdown($dropdown2);
removeOptionWithValue($dropdown2, selectedProps.value);
});
$dropdown2.on("change", function () {
var selectedProps = getOptionProps($(this));
populateDropdown($dropdown1);
removeOptionWithValue($dropdown1, selectedProps.value);
});
<select id="myselect">
<option value="1">Mr</option>
<option value="2">Mrs</option>
<option value="3">Ms</option>
<option value="4">Dr</option>
<option value="5">Prof</option>
</select>
<select id="youSelect">
<option value="1">Mr</option>
<option value="2">Mrs</option>
<option value="3">Ms</option>
<option value="4">Dr</option>
<option value="5">Prof</option>
</select>
Now on click of a button I want to set mySelect option:selected value in youSelect So for this I had done this
$('#youSelect option:selected').text($('#myselect option:selected').text())
but its not working.Please guide how to solve this.
Simply do:
$('#youSelect').val($('#myselect').val());
You are matching the values, not the text.
Edit: Based on your edited question, you're probably looking at the same situation as this question
var _mySelectText = $("#myselect option:selected").text();
$("#youSelect option").filter(function () {
return this.text === _mySelectText;
}).attr("selected", "selected");
$("#youSelect").val("thevalue");
just make sure the value in the options tags matches the value in the val method.
var myValue = $("#myselect option:selected").text();
var secondoption = $("#youSelect")[0];
for (var i = 0, sL = secondoption.length; i < sL; i++) {
if (secondoption.options[i].text == myValue) {
secondoption.selectedIndex = i;
break;
}
}

Use this.
$(selector_to_your_button).on('click',function(){
$('#youSelect).val($("#myselect").val());
});
I am generating a html select boxes dynamically. The select boxes have a name:value pair of the number of total select boxes. That said, if I have 4 select boxes, then in each of the select box should have options like:
<select id="dynamic_id" >
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
</select>
. That I've accomplished already. Now I want option 1 to be selected for the first select box, option 2 to be selected for the second select box and so on.
(I am a complete noob and maintainig someone's code. So the code is pretty ugly but if you guys should need it...I will post it.)
EDIT
At the moment, abdulla's suggestion is working a bit but not fully. It always selects the first item only. Guys, this is a horrible code, but I think only it can help you understand mistakes I'm making:
var r_count=0;
$(document).ready(function(){
var newId; var tableName; var display_table;
$(".clickable").each(function(i,l){
$(l).click(function(){
var parentId = $(this).parents("div")[0].id;
var li = $(this).parents("li")[0];
var liIndex = $(li).parent().find("li").index(li);
newId = parentId + "_" + liIndex;
if(this.checked) {
display_table = $("#display_board");
var newtr = $(".data_table_template").clone();
tableName = $($(this).parents("table")[0]).find("th").text().trim();
var columnName = $(this).parent().text().trim();
newtr.attr("id",newId);
newtr.attr("class","");
newtr.show();
newtr.find("td").each(function(i,l){
if(i==0)
$(this).html(columnName)
else if(i==2)
$(this).html(tableName)
else if(i==3){
$(this).each(function(i,l){
$(this).find("#checkbox").attr("id", "chkbx_" + newId);
});
}
else if(i==4){
$(this).each(function(i,l){
//$(this).find("#select").html();
/* Generate new id for the table item dynamically*/
$(this).find("#select").attr("id", "sort_type_" + newId);
$(this).find(".sel1").attr("name", "sort_type_" + newId);
$(this).find("#checkbox").attr("id", "sort_type_" + newId);
});
}
else if(i==5)
$(this).each(function(m,l){
/* Generate new id for the table item dynamically*/
$(this).find("#select2").attr("id", "sort_order_" + newId);
$(this).find(".sel2").attr("name", "sort_order_" + newId);
});
});
display_table.append(newtr);
r_count++;
// addOption is from another jquery plugin
$(".sel2").addOption(r_count+1, r_count+1);
// as suggested in the answer
$('select').each(function (index, item) {
$(this).children('option:nth-child(' + (index +1) + ')').attr('selected', 'selected');
});
} else {
r_count--;
//$("#" + newId).find("#chkbx_"+newId).attr('checked','');
$("#" + newId).remove();
$(".sel2").addOption(r_count, r_count);
}
}
);
});
Only the select boxes in the 5th column are in consideration.
$('select').each(function(index, value) {
this.selectedIndex = index;
});
You could generate the select boxes with the option that you wanted having the attribute:
selected="true"
This also works, by setting the selected="selected" property on the children..
$('select').each(function (index, item) {
$(this).children('option:nth-child(' + (index +1) + ')').attr('selected', 'selected');
});
if i have understood correctly, i assume you have the following markup
<select id="dynamic_id" >
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
</select><br/>
<select id="dynamic_id2" >
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
</select><br/>
<select id="dynamic_id3" >
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
</select><br/>
<select id="dynamic_id4" >
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
<option value=4>4</option>
</select>
you can try
$("select").each(function(index){
index=index+1;
$(this).find("option[value='"+index+"']").attr("selected","selected");
});
here is the fiddle http://jsfiddle.net/skyWJ/
$('select').each(function(index, value) {
$(this).val(index + 1).change();
});
hello
i need to load page based on the results of dropdown box. for example in my code i have value="userlog". if this selected it will load userlog.php and remove itself so that only userlog.php is being used. thanks
<select onchange="updatePage(this.value)">
<option value="">Select a report</option>
<option value="userlog">User Logs</option>
<option value="actionlog">Action Logs</option>
</select>
<select id="select_page">
<option value="">Select a report</option>
<option value="userlog">User Logs</option>
<option value="actionlog">Action Logs</option>
</select>
$('#select_page').change(function() {
var $el = $(this);
if($el.val() != '') {
$('#page').load($el.val()+'.php');
$el.find('option:selected').remove();
}
});
On change event you will get the selected options value. Using this value you can decide what you want to do.
something like this :
$(document).ready(function() {
$("select option ").each(function() {
if (location.href.indexOf($(this).val()) >= 0) {
$(this).remove();
}
});
$('select').change(function() {
var obj = $(this);
location.href = obj.val() + ".php";
});
});
