This is a follow up question. I am trying to get a input box to be hidden when a pull-down menu has the value "tid and acc". I am at a loss why this code isn't working, any help would much appreciated! Here is a link on jfiddle: http://jsfiddle.net/Mm7c7/
<script>
$('#rule-type').change(function() {
var val = $(this).val();
if (val == 'tid and acc') {
$('#tid-acc').show();
}
else {
$('#tid-acc').hide();
}
});
</script>
<select id="rule-type">
<option value="" selected="selected">None</option>
<option value="tid">tid</option>
<option value="tid and acc">tid and acc</option>
<option value="xid">xid</option>
</select>
<input id="tid-acc">
Your script is being evaluated before your element is ready. Placing the script in a $(document).ready() or after the content it affects will solve the problem
http://jsfiddle.net/Wx8Jf/2
$(document).ready(function(){
$('#rule-type').change(function() {
var val = $(this).val();
if (val == 'tid and acc') {
$('#tid-acc').show();
}
else {
$('#tid-acc').hide();
}
});
});
Couple problems:
You'll either need to wrap the function in $(function(){}) to ensure DOM is ready, or drop it below your HTML (the former is recommended). If you don't wrap it (or drop it), then the script is executed before the elements have actually been rendered, causing $('#rule-type') to be undefined.
Your logic is incorrect (according to your explanation). Your current logic says to hide the input box when anything other than tid and acc is selected.
Working version:
<script>
$(function(){
$('#rule-type').change(function() {
var val = $(this).val();
if (val == 'tid and acc') {
$('#tid-acc').hide();
}
else {
$('#tid-acc').show();
}
});
});
</script>
<select id="rule-type">
<option value="" selected="selected">None</option>
<option value="tid">tid</option>
<option value="tid and acc">tid and acc</option>
<option value="xid">xid</option>
</select>
<input id="tid-acc" />
http://jsfiddle.net/dbrecht/QwkKf/
Take a look here for a working sample: http://jsfiddle.net/Mm7c7/1/
HTML:
<select id="rule-type">
<option value="" selected="selected">None</option>
<option value="tid">tid</option>
<option value="tid and acc">tid and acc</option>
<option value="xid">xid</option>
</select>
<input id="tid-acc">
Javascript:
$('#rule-type').change(function() {
var val = $(this).val();
if (val == 'tid and acc') {
$('#tid-acc').show();
}
else {
$('#tid-acc').hide();
}
});

I am using a jquery code found on Stakeoverflow to remove duplication value in the dropdown. my problem is the jquery code worked for the first dropdown but will not work for the second dropdown any help will be welcome
1st dropdown
<select id="AssetStoredWhere" name="AssetStoredWhere" class="form-control js-example-disabled-results
select">
<option value="#ViewBag.AssetStoredWhere">#ViewBag.AssetStoredWhere</option>
<option value="UK">UK</option>
<option value="EU">EU</option>
<option value="Worldwide">Worldwide</option>
</select>
2bd Dropdown
<select asp-for="Dpiaavailable" id="Dpiaavailable" name="Dpiaavailable" class="form-control js-
example-disabled-results select">
<option value="#ViewBag.Dpiaavailable">#ViewBag.DpiaavailableValue</option>
<option value="False">No</option>
<option value="True">Yes</option>
</select>
Jquery code
var seen = {};
jQuery('.select').children().each(function () {
var txt = jQuery(this).attr('value');
if (seen[txt]) {
jQuery(this).remove();
} else {
seen[txt] = true;
}
});
You need another loop to iterate through the select elements themselves, not through the option elements of every select as one. Try this:
$('.select').each(function() {
var seen = {};
$(this).children().each(function() {
var $option = $(this);
if (seen[$option.val()]) {
$option.remove();
} else {
seen[$option.val()] = true;
}
});
});
I am have been searched too much on net but nothing found.
I have 2 select options tag.
I want to show option value in the input tag by multiplying option tag value whatever it is.
and selecting 2nd option tag I want to assign 2nd option tag value to 1st option tag value.
and I also want to multiply that values as the 1st options value have before.
how to do this?
here is my code.
My 1st options tag.
<select name="" id="test">
<option selected="" value="0" disabled='disabled'>Select Duration</option>
<option value="1">1/month</option>
<option value="2">2/month</option>
<option value="3">3/month</option>
<option value="6">6/month</option>
<option value="12">12/month</option>
</select>
<input type="text" data-val="9" id="price_value" style="border:1px solid #0a0; padding:1px 10px; color: #f90;" value="0" size="5"/><br>
Here is 2nd option tag.
<select id="plan">
<option value='Basic'>Basic</option>
<option value='Standard'>Standard</option>
<option value='Professional'>Professional</option>
<option value='Enterprice'>Enterprise</option>
</select>
here is JS.
$('#test').on('change',function(e){
var input = $(this).next('input[type="text"]');
var value = $(this).find('option:selected').val();
input.val( input.data('val') * parseInt(value) );
});
$('#plan').on('change',function(e) {
var plan = $(this).find('option:selected').val();
var price_value = $('#price_value');
if (plan == "Basic") {
price_value.removeAttr('data-val');
price_value.attr('data-val','9');
}
else if (plan == "Standard"){
price_value.removeAttr('data-val');
price_value.attr('data-val','19');
}
else if (plan == "Professional"){
price_value.removeAttr('data-val');
price_value.attr('data-val','29');
}
else if (plan == "Enterprice") {
price_value.removeAttr('data-val');
price_value.attr('data-val','59');
}
});
Here is Demo
Changes
Use $(this).val() instead of $(this).find('option:selected').val() to fetch select value. or even better use this.value
use .data() to set value like price_value.data('val', 9); instead of price_value.attr('data-val','9');
No need to use price_value.removeAttr('data-val');
Code
$('#test').on('change',function(e){
var input = $(this).next('input[type="text"]');
var value = $(this).val(); //Or this.value
input.val( input.data('val') * parseInt(value, 10) );
});
$('#plan').on('change',function(e) {
var plan = $(this).val();
var price_value = $('#price_value');
if (plan == "Basic") {
price_value.data('val',9);
}
else if (plan == "Standard"){
price_value.data('val',19);
}
else if (plan == "Professional"){
price_value.data('val',29);2
}
else if (plan == "Enterprice") {
price_value.data('val',59);
}
$('#test').trigger('change'); //Trigger $('#test') change event
});
DEMO
This solution would work if you are okay with changing your HTML a bit:
<select id="plan">
<option value='9'>Basic</option>
<option value='19'>Standard</option>
<option value='29'>Professional</option>
<option value='59'>Enterprise</option>
</select>
Then simply use:
$('#test, #plan').on('change',function() {
var valueOne = $('#test').val();
var valueTwo = $('#plan').val();
$('#price_value').val(parseInt(valueOne) * parseInt(valueTwo));
});
That's all!
I have a select with loads of options. (Code below shortened for sake of example).
I want it to set the value of the input textfield "hoh" to "10" when you click/select all dropdown options, except one, that should set it to 50.
I imagined something like this would work, but its not. What am I doing wrong here?
<select>
<option onselect="document.getElementById('hoh').value = '50'">Hey</option>
<option onselect="document.getElementById('hoh').value = '10'">Ho</option>
<option onselect="document.getElementById('hoh').value = '10'">Lo</option>
....
</select>
<input type="text" id="hoh" value="10">
Something like this should work:
<script>
function myFunc(val) {
if (val == '50') {
document.getElementById('hoh').value = val;
} else {
document.getElementById('hoh').value = '10';
}
}
</script>
<select onchange="myFunc(this.value)">
<option value="1">one</option>
<option value="2">two</option>
<option value="50">fifty</option>
</select>
http://jsfiddle.net/isherwood/LH57d/3
The onselect event refers to selecting (or highlighting) text. To trigger an action when a dropbox selection changes, use the onchange event trigger for the <select> element.
E.g. Since you didn't already set the value attribute of your option tags.
<select id="myselect" onchange="myFunction()">
<option value="50">Hey</option>
<option value="10">Ho</option>
<option value="10">Lo</option>
....
</select>
and somewhere inside of a <script> tag (presumably in your HTML header) you define your javascript function.
<script type="text/javascript>
function myFunction() {
var dropbox = document.getElementById('myselect');
document.getElementById('hoh').value = dropbox[dropbox.selectedIndex].value;
}
</script>
I'm not sure it's wise to repeat the same value among different options in a droplist, but you could expand on this to implement the result other ways, such as if the sole option which will have value 50 is in a certain position, you could compare the selectedIndex to that position.
you could add an onchange event trigger to the select, and use the value of an option to show in the textbox
see http://jsfiddle.net/Icepickle/5g5pg/ here
<select onchange="setValue(this, 'hoh')">
<option>-- select --</option>
<option value="10">Test</option>
<option value="50">Test 2</option>
</select>
<input type="text" id="hoh" />
with function setValue as
function setValue(source, target) {
var tg = document.getElementById(target);
if (!tg) {
alert('No target element found');
return;
}
if (source.selectedIndex <= 0) {
tg.value = '';
return;
}
var opt = source.options[source.selectedIndex];
tg.value = opt.value;
}
Try this code
var inp = document.getElementById('hoh');
sel.onchange = function(){
var v = this.value;
if( v !== '50'){
v = '10';
}
inp.value = v;
};
have this code, i want to convert it to be able to allow the user to pick ANY possible select and have div [id='setprice'] show up or something to that effect. currently i have 4 options, but it could be up to 10+ depends on how many are in the database. but it shouldn't matter, i just want which ever gets selected to open the setprice div. Thanks.
$("#category").change(function () {
$("#setprice").hide();
if ($(this).val() == "cow") { $("[id='setprice']").show(); }
else if ($(this).val() == "dog") { $("[id='setprice']").show(); }
else if ($(this).val() == "monkey") { $("[id='setprice']").show(); }
else if ($(this).val() == "kungfoo") { $("[id='setprice']").show(); }
});
HTML
<select id="category">
<option value=''>Select</option>
<option value='cow'>Cow</option>
<option value='dog'>Dog</option>
<option value='monkey'>Monkey</option>
<option value='kungfoo'>kungfoo</option>
</select>
<div id='setprice'>this is hidden onload, then shows on any #category selection</div>
Seems to be alot of cofusion in what im asking, These options i've given are random names, the categories that are going to be loaded, are from a database and more could be added depending how it expands, so i want the script to not show div=setprice, but when anything gets selected in #category to open setprice.
You will need to call the function only when the value of the select box isn't empty.
$("#category").change(function () {
$("#setprice").toggle(!!this.value);
});
Here is a working fiddle.
This is the cleanest you will get this.
DEMO
$("#category").change(function () {
$("#setprice").toggle(!!this.value);
});
The $("#setprice").toggle(!!this.value); is just a way to use a boolean inside the .toggle() method,
otherwise you do it equally like:
var $setPriceEl = $("#setprice");
$("#category").change(function () {
$setPriceEl.hide(); // hide by default
if(this.value) $setPriceEl.show(); // show only if has value
});
or even:
$("#category").change(function () {
$("#setprice")[this.value ? "show" : "hide" ]();
});
Please find the answer below ...
HTML :
<select id="category">
<option value=''>Select</option>
<option value='cow'>Cow</option>
<option value='dog'>Dog</option>
<option value='monkey'>Monkey</option>
<option value='kungfoo'>kungfoo</option>
</select>
<div id='setprice' style="display:none;">this is hidden onload,
then shows on any #category selection</div>
JQUERY :
$(document).ready(function(){
$("#category").change(function() {
$("#category option:selected" ).each(function() {
var str = $( this ).text();
if(str == "Select"){
$("#setprice").hide();
}else{
$("#setprice").show();
$("#setprice").text(str);
}
});
}).trigger("change");
});
I would like to change the style of a text field based on the value selected in a combo box. Specifically, what I'd like to do is make the txtDepartment field gray and marked as "read only" if the option value selected in cboSource is 1. I've tried the code below, but I imagine my style code at least is wrong, if not other things. Any help appreciated. Thanks!
<select name="cboSource" id="cboSource" onClick="displayDepartment(this);">
<option value = 1>Source 1</option>
<option value = 2>Source 2</option>
</select>
<input name="txtDepartment" type="text" id="txtDepartment" size="6" maxlength="6"></p>
<script>
function displayDepartment(obj)
{
var selectedValue = obj.value;
var txtDepartment = document.getElementById("txtDepartment");
if (selectedValue == "1")
{
txtDepartment.style.display = "Disabled style='background-color:#E8E8E8'";
}
}
</script>
txtDepartment.style.backgroundColor = "#E8E8E8";
txtDepartment.disabled = 'disabled';
with jQuery your whole function gets a lot smaller:
function displayDepartment(obj)
{
if($(obj).value=="1") {
$("#txtDepartment").css('background-color','#E8E8E8');
$("#txtDepartment").disabled ='disabled'
}
}
First, use onchange on cboSource.
Then:
if(selectedValue == "1")
txtDepartment.disabled = 'disabled';
Set the disabled attribute for your element
// on
txtDepartment.setAttribute("disabled","disabled")
// off
txtDepartment.removeAttribute("disabled")
possible solution using jQuery:
<style>
.disabled {
background-color:#E8E8E8;
}
</style>
<script language="javascript">
$(document).ready(function() {
var txtDepartment = $("#txtDepartment");
var cboSource = $("#cboSource");
cboSource.change(function() {
txtDepartment.removeClass().removeAttr("disabled");
if (cboSource.val() == 1) {
txtDepartment.addClass("disabled").attr("disabled", true);
}
});
});
</script>
<select name="cboSource" id="cboSource">
<option value = 0>Choose</option>
<option value = 1>Source 1</option>
<option value = 2>Source 2</option>
</select>
<input name="txtDepartment" type="text" id="txtDepartment" size="6" maxlength="6"></p>
In my opinion onclick is more suitable as on change has different meaning for different browser
Try this
<select name="cboSource" id="cboSource" onClick="displayDepartment(this);">
<option value = 1>Source 1</option>
<option value = 2>Source 2</option>
</select>
<input name="txtDepartment" type="text" id="txtDepartment" size="6" maxlength="6"></p>
<script>
function displayDepartment(obj)
{
var txtDepartment = document.getElementById("txtDepartment");
txtDepartment.disabled = false;
txtDepartment.style = "";
if (obj.value == "1")
{
txtDepartment.style = "background-color:#E8E8E8";
txtDepartment.disabled = true;
}
}
</script>
