I am trying to create a select tag that holds values in it and if two out of the five values are selected another select box will show on the screen. I have tried searching for this and found where people are using javascript and using the onchange event but for some reason I cannot get it to work. The toggle id is the one I want to show up if individual or short term is selected if not I want it to be hidden. The code is below and thanks for your help in advance. I didn't include the javascript because I deleted it all but I have tried it a few different ways with no luck. I am thinking it is the way I have the form laid out.
HTML
<tr>
<td class='txt'><span>*</span>Coverage Needed?</td>
<td>
<select name="ins_type" id='ins_options' onChange="toggle();">
<option>Select...</option>
<option value="Group">Group Insurance</option>
<option value="Individual">Individual Insurance</option>
<option value="Short Term">Short Term Insurance</option>
<option value="Medicare">Medicare</option>
<option value="Life">Life Insurance</option>
</select>
</td>
<td ><div id='toggle'><span>*</span>How Many?
<select name='applicants' id='applicants' >
<option>Select...</option>
<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>
<option value='6'>6</option>
<option value='7'>7</option>
<option value='1'>8</option>
<option value='9'>9</option>
<option value='10'>10</option>
</select>
</div>
</td>
</tr>
Javascript (I was thinking something like this should work)
<script type="text/javascript">
function toggle() {
if (document.getElementById("ins_options").options
[getElementById("ins_options").selectedIndex].value == "Individual") {
document.getElementById("toggle").style.display = "none";
} else {
document.getElementById("toggle").style.display = "block";
}
}
</script>
You're missing document in your selected index lookup - http://jsfiddle.net/VfEyW/
So instead of
[getElementById("ins_options").selectedIndex]
try
[document.getElementById("ins_options").selectedIndex]
...
UPDATE
To check against 2 values you can do this
function toggle() {
var val = document.getElementById("ins_options").options[document.getElementById("ins_options").selectedIndex].value;
if ( val == "Individual" || val == "Short Term" ) {
document.getElementById("toggle").style.display = "none";
} else {
document.getElementById("toggle").style.display = "block";
}
}

Is it possible to hide options in a select/dropdown with jQuery based on the user's selection from a previous dropdown e.g:
If user is 8 (Age Select/Dropdown), and chooses subject English (Subject Select/Dropdown) then hide Location 2 from (Locations dropdown)?
<select name="age">
<option value="8">8</div>
<option value="9">9</div>
<option value="10">10</div>
<option value="11">11</div>
</select>
<select name="subject">
<option value="eng">English</div>
<option value="maths">Maths</div>
<option value="science">Science</div>
</select>
<select name="subject">
<option value="loc-1">Location One</div>
<option value="loc-2">Location Two</div>
<option value="loc-3">Location Three</div>
</select>
Thank you!
you just need to add change function to your drop-down and according to your requirement you need to add your logic. see below example.
$(document).ready(function(){
$("#age").change(function(){
hideOption();
})
$("#subject").change(function(){
hideOption();
})
})
function hideOption(){
var age=$("#age").val();
var subject=$("#subject").val();
if(age==8 && subject=="Maths"){
$("#location [value='Location Two']").hide();
}
else{
$("#location [value='Location Two']").show();
}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="age" id='age'>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
</select>
<select name="subject" id='subject'>
<option value="English">English</option>
<option value="Maths">Maths</option>
<option value="Science">Science</option>
</select>
<select name="Location" id='location'>
<option value="Location One">Location One</option>
<option value="Location Two">Location Two</option>
<option value="Location Three">Location Three</option>
</select>
You can do something like below
$(document).on('change', '.age', function(e){
var val = $(this).val();
var subject = $('.subject').find(":selected").val();
if(val == 8 && subject == 'English' ){
$('.location option[value="Two"]').hide();
} else {
$('.location option[value="Two"]').show();
}
})
$(document).on('change', '.subject', function(e){
var age = $('.age').find(":selected").val();
var val = $(this).val();
if(age == 8 && val == 'English' ){
$('.location option[value="Two"]').hide();
} else {
$('.location option[value="Two"]').show();
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="age" class="age">
<option >select</8>
<option value="8">8</8>
<option value="9">9</8>
<option value="10">10</8>
<option value="11">11</8>
</select>
<select name="subject" class="subject">
<option value="English">English</8>
<option value="Maths">Maths</8>
<option value="Science">Science</8>
</select>
<select name="location" class="location">
<option value="One">Location One</8>
<option value="Two">Location Two</8>
<option value="Three">Location Three</8>
</select>
With jQuery you can use .hide() and .show() to toggle element visibility. First however, you can check if the value of a select (for example age) was changed. Based on the logic you want to have, you can for example check what the value of the change was and do something if it matches a condition.
For example:
$( "#age-select" ).change(function() {
var value = $(this).val();
if(value == 8) {
$("#location-two").hide();
} else {
$("#location-two").show();
}
});
However, notice that I added an id for the "Location Two" option ("location-two") and for the age select element. Also, to make this work properly, you have to fix the values so that they're not all 8 and fix the closing tags of the elements (not ).
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>
<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>
<select name="my_options" id="firstblock" onchange="disable(2,this.value);">

</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">
<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">

I want to get a value from few dropdown, this few dropdown have a same name in
a table of database.And user can see only one dropdown base on their previous selection, but I can't detect which dropdown is selected by users.So I make something bellow:
$dropvalue = "GetFromJavaascriptBellow" //use to get value from javascript bellow
<select id="dropdown1" name="dropdown1">
<option selected disabled>-- Please select a option --</option>
<option value="abc">abc</option>
<option value="def">def</option>
<option value="ghi">ghi</option>
</select>
<select id="dropdown2" name="dropdown2">
<option selected disabled>-- Please select a option --</option>
<option value="123">123</option>
<option value="456">456</option>
<option value="789">789</option>
</select>
<select id="dropdown3" name="dropdown3">
<option selected disabled>-- Please select a option --</option>
<option value="aaa">aaa</option>
<option value="bbb">bbb</option>
<option value="ccc">ccc</option>
</select>
<script>
$('#dropdown1').change(function () {
if ( this.value != '' || this.value != NULL)
{
$dropvalue = this.value //This line is what I can't do (is it possible php variable get value from javascript?)
}
else
{
}
});
$('#dropdown2').change(function () {
if ( this.value != '' || this.value != NULL)
{
$dropvalue = this.value //This line is what I can't do (is it possible php variable get value from javascript?)
}
else
{
}
});
$('#dropdown3').change(function () {
if ( this.value != '' || this.value != NULL)
{
$dropvalue = this.value //This line is what I can't do (is it possible php variable get value from javascript?)
}
else
{
}
});
</script>
My current solution is using ajax to get all of the value from all drop down, and set the default value ='0' to all dropdown, in ajax using if else statement to check which dropdown is not equal to 0 to confirm what is my value and which dropdown is.But this way is conflict with my another function, so I finding another way to did it
Try this. Use querySelectorAll
x=document.querySelectorAll("select.abc");
for(i=0;i<x.length;i++){
x[i].addEventListener("change",function(){
console.log(this.value); // your ajax call or whatever function you want excute
});
}
<select id="dropdown1" name="dropdown1" class="abc">
<option selected disabled>-- Please select a option --</option>
<option value="abc">abc</option>
<option value="def">def</option>
<option value="ghi">ghi</option>
</select>
<select id="dropdown2" name="dropdown2" class="abc">
<option selected disabled>-- Please select a option --</option>
<option value="123">123</option>
<option value="456">456</option>
<option value="789">789</option>
</select>
<select id="dropdown3" name="dropdown3">
<option selected disabled>-- Please select a option --</option>
<option value="aaa">aaa</option>
<option value="bbb">bbb</option>
<option value="ccc">ccc</option>
</select>
I have two dropdowns. I want the second dropdown, Assign value to be set to null when the specific value which is student from the first dropdown is chosen.
First dropdown:
<select name="Reg">
<option value="">Choose</option>
<option value="admin">Admin</option>
<option value="student">Student</option>
</select>
This is the second dropdown which is hidden, shown only when Reg with value admin is chosen.
<select name="Assign">
<option value="">Choose</option>
<?php
$sql=odbc_exec($conn,'SELECT AssignCd, AssignNm FROM AssignList');
if(odbc_fetch_row($sql))
{
$AssignCd= odbc_result($sql, "AssignCd");
$AssignNm= odbc_result($sql, "AssignNm");
echo "<option value='".$AssignCd."'>".$AssignNm."</option>";
}
?>
</select>
I tried by doing the following but it doesn't work.
Please Help.
if($("#Reg").val("student");) {
$("#AssignCd").val("");
$("#AssignNm").val("");
}
UPDATED:
When Admin is selected, Assign with admin is chosen will be automatically selected. The problem is when I change my option to Student, the supposed value student is chosen is not shown.
How can I make the Assign value of both Admin and Student stay as it is and not jumbled up between them?
This is my code :
fiddle
$(document).ready(function() {
$("#Reg").on("change", function() {
if ($(this).find("option:selected").text() === 'Admin') {
$("#Assign").show();
$('select[name="Assign"] option[name="student_assign"]').attr("disabled",true).prop("selected", false).wrap('<span>');
$('select[name="Assign"] option[name="admin_assign"]').prop('selected',true);
}
else if ($(this).find("option:selected").text() === 'Student') {
$("#Assign").show();
$('select[name="Assign"] option[name="student_assign"]').prop('selected',true);
} else {
$("#Assign").hide().attr("disabled"," ");
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<select name="Reg" id="Reg">
<option value="">Choose</option>
<option value="admin">Admin</option>
<option value="student">Student</option>
</select>
<select name="Assign" id="Assign">
<option value=" ">Choose</option>
<option name ="student_assign" value="student_assign">student is chosen</option>
<option name ="admin_assign" value="admin_assign">admin is chosen</option>
</select>
$('select[name="Reg"]').on('change', function() {}) this will trigger when you select an option in your select
$(this).find("option:selected").val() == "student" this will see if you have select an option with value "student"
$('select[name="Assign"] option[value="AssignCd"]').text(""); this sets the text of the option with value = AssignCd to empty
This is how far we can go without showing us your generated html for <select name="Assign">
$('select[name="Reg"]').on('change', function() {
if ($(this).find("option:selected").val() == "student") {
$('select[name="Assign"] option[value="AssignCd"]').text("");
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="Reg">
<option value="">Choose</option>
<option value="admin">Admin</option>
<option value="student">Student</option>
</select>
<select name="Assign">
<option value="AssignCd">AssignNm</option>
</select>
Update
There is no need to use .wrap() as far as i can see, use .hide() / .show() look at the example below.
$(document).ready(function() {
$("#Reg").on("change", function() {
if ($(this).find("option:selected").text() === 'Admin') {
$("#Assign").show();
$('select[name="Assign"] option[name="student_assign"]').attr("disabled", true).prop("selected", false).hide();
$('select[name="Assign"] option[name="admin_assign"]').prop('selected', true);
} else if ($(this).find("option:selected").text() === 'Student') {
$('select[name="Assign"] option[name="student_assign"]').attr("disabled", false).prop("selected", true).show()
$('select[name="Assign"] option[name="student_assign"]').prop('selected', true);
} else {
$("#Assign").hide().attr("disabled", " ");
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<select name="Reg" id="Reg">
<option value="">Choose</option>
<option value="admin">Admin</option>
<option value="student">Student</option>
</select>
<select name="Assign" id="Assign">
<option value=" ">Choose</option>
<option name ="student_assign" value="student_assign">student is chosen</option>
<option name ="admin_assign" value="admin_assign">admin is chosen</option>
</select>
<select name="Reg" id="Reg">
<option value="">Choose</option>
<option value="admin">Admin</option>
<option value="student">Student</option>
</select>
First of all #<selector> is used to select Dom elements which have an id <selector>. You cannot access them with the name attribute and id selector.
As for your issue. you need to use the on change event of the first drop down to decide the visibility of the second drop down.
<select name="Assign" id="Assign">
<option value="">Choose</option>
....
....
$('#Assign').hide(); // first hide it so they cannot see it
$(document).on('change', '#Reg', function(e){
if($(this).val()=='admin'){
$('#Assign').show();
}else{
$('#Assign').val('').hide();
}
})
My website is created in ASP classic - VBScript (not my choice and is a language I've not had experience with before this). I'm trying to create a webpage where in it: A dropdown menu reveals an additional dropdown based on what was selected in the first one. I'm trying to use a javascript function to achieve this.
Example:
In the first dropdown the user chooses ice cream or crisps.
Based on what the user selects another dropdown gives the choice of flavour.
Ice cream: vanilla, chocolate, mint.
Crisps: ready salted, cheese & onion, salt & vinegar.
This is what my code currently looks like:
HTML
<select id="food" onchange="fctCheck(this.value)">
<option value="">Choose an item</option>
<option value="icecream">Ice cream</option>
<option value="crisps">Crisps</option>
</select>
<select id="icecream" style="display:none">
<option value="vanilla">Vanilla</option>
<option value="chocolate">Chocolate</option>
<option value="mint">Mint</option>
</select>
<select id="crisps" style="display:none">
<option value="readysalted">Ready Salted</option>
<option value="cheeseandonion">Cheese and Onion</option>
<option value="saltandvinegar">Salt and Vinegar</option>
</select>
.
javascript
function fctCheck(food)
{
if (food == "")
{document.getElementById(food).style.display = "none";}
else
{document.getElementById(food).style.display = "block";}
}
as mentioned by st3inn this.value is absolutely fine - there is just the typo by document.getElement==>B<==yId.
But your code has the disadvantage, that a user could select both options and so both sub-selections would be visible.
You could avoid this by first hiding all sub-selections before showing the one for the selected item. This could be done that way (via the addiotional name-attribute, or, if you choose to work with jQuery you could do something more sophisticated instead):
Example (with comments) on JSFiddle
Javascript:
function fctCheck(food) {
var elems = document.getElementsByName("subselector");
for (var i = 0; i < elems.length; i++) {
elems.item(i).style.display = "none";
}
document.getElementById(food).style.display = "block";
}
HTML:
<select id="food"onchange="fctCheck(this.value);">
<option value="">Choose an item</option>
<option value="icecream">Ice cream</option>
<option value="crisps">Crisps</option>
</select>
<select id="icecream" name="subselector" style="display:none">
<option value="vanilla">Vanilla</option>
<option value="chocolate">Chocolate</option>
<option value="mint">Mint</option>
</select>
<select id="crisps" name="subselector" style="display:none">
<option value="readysalted">Ready Salted</option>
<option value="cheeseandonion">Cheese and Onion</option>
<option value="saltandvinegar">Salt and Vinegar</option>
</select>
Cheers,
Florian
You need to check for option value instead:
fctCheck(this.options[ this.options.selectedIndex ].value)
this.options is collection of <option> elements inside your current <select>, and this.options.selectedIndex is integer value that show what option currently selected.
BTW you have an typo in your code:
document.getElementbyId
should be
document.getElementById
See jsFiddle demo
You just have a typo.
function fctCheck(food)
{
if (food == "") {
document.getElementById(food).style.display = "none";}
} else {
document.getElementById(food).style.display = "block";
}
}
should work.
this.value
is equivalent to
this.options[this.options.selectedIndex].value
