I've a dropdown
<select id="ddl1">
<option value="0">number</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="8">8</option>
</select>
now what i'm doing is as soon as user clicks on ddl1 i change its default value to 4 like this
$(function () {
var defaultValue = "4";
$('#ddl1').click(function () {
var select_val = $('#ddl1').val();
if (select_val == "0")
$('#ddl1').val(defaultValue);
});
});
but now the problem is when user tries to select the default option of dropdown i.e number, option 4 is selected. Any ideas how to fix this?
The problem is when the user just clicks on dropdown -> option4 must be selected and when user clicks on option number -> option number must be selected instead of option 4.
Not sure why you're doing that but focusin or focus events can help you achieve that as follows:
$(function() {
$('#ddl1').on('focusin', function() {
this.value != 0 || $(this).val( 4 );
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select id="ddl1">
<option value="0">number</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="8">8</option>
</select>
You should call this function on change, not click - else, like you said, as soon as you click an option is selected.
$('#ddl1').change(function () {
DEMO
Edit: You should use a class to give the feel of the default option, you don't actually want it set to selected EACH time the user clicks:
<select id="ddl1">
<option value="0">number</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4" class="default">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
</select>
.default {
color: blue;
}
is this what you're looking for? http://jsfiddle.net/swm53ran/84/
$(function () {
var defaultValue = "4";
var count = 0;
$('#ddl1').click(function () {
if (count < 1) {
$('#ddl1').val(defaultValue);
count++;
}
});
});

I have been hitting my head cuz I can't think on a way to get this to work ( I'm new with Jquery )
So.. I have a select input field in a form with number options.. I want to check which of the options the user selected and add a DIV the number of times the user selected ( from 0 to 10 ) and if the user selects a number lower than the one he previously chose delete the DIVs previously added and add the ones he now chose (if he selects number 3 add 3 DIVs, if he now selects 2 because he was just mistaken then just show 2 instead of the 3)
I know how to get the number the user selected with the .change event listener and the :selected.val() method.. my problem is appending the divs that number of times the user selected, and deleting them if the user selects a number lower than.
Please i don't know how to make this work!
In your change function, first clear the wrapper and then append the divs in a loop
var beneficiarioDiv = '<div class="beneficiario-wrap"><label for="nombre_bene">Nombre y Apellido</label><input type="text" name="nombre_bene" value=""><label for="nombre_bene">Cedula beneficiario</label><div><select name="cedulabene_tipo"><option value="Venezolano" selected>V </option><option value="Extranjero">E </option></select> <input type="text" name="cedulabene_no" value="" maxlength="8"></div><label for="edad_bene">Edad beneficiario</label><input type="text" name="edad_bene" value=""></div>';
$('#beneficiarios').change(function() {
var beneficiarios = $('#beneficiarios :selected').val();
// this gives me the value that the user selected
$('.beneficiarios-wrapper').empty();
while (beneficiarios--) {
$('.beneficiarios-wrapper').append(beneficiarioDiv);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label for="beneficiarios">Cantidad de beneficiarios</label>
<select name="beneficiarios" id="beneficiarios">
<option value="0">0</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="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
</select>
<div class="beneficiarios-wrapper"></div>
You can clear the div on change event. Then use a for loop to append div
const divToAppend = '<div>test</div>';
let number = $('#beneficiarios').val();
$('#beneficiarios').on('change', function () {
$('#placeholder').html('');
number = $(this).val();
for (let i = 0; i < number; i++) {
$('#placeholder').append(divToAppend);
}
});
<label for="beneficiarios">Cantidad de beneficiarios</label>
<select name="beneficiarios" id="beneficiarios">
<option value="0">0</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="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
</select>
<div id="placeholder"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
You could just append the divs in a loop:
var b = = $('#beneficiarios :selected').val();
while(b--) {
$(".beneficiarios-wrapper").append("<div>"+b+"</div>")
}
I have a dropdown that will change with respect to the first value (i.e from_value).
What I'm trying to do is. There will be numbers from 1 to 10.
So if the first value is selected as 2, then the second value (i.e to_value) should be populated with 2 to 10 in the dropdown.
Below is my code and I'm not sure to run the loop here. Could someone help me in running the loop and do my task.
In other words - If the first drop down is selected with value 2, then the second dropdown should populate with 2,3,4,5,6,7,8,9,10
If the first dropdown is selected with 8, then the second dropdown should show 8,9,10
$("#from_value").change(function(){
var from_value = $("#from_value").val();
$("div.to_value").html('<label>To Value</label><select name="to_value" id="to_value"><option>'+ from_value +'</option></select>');
});
try
HTML
<select id="from_value">
<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="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
</select>
<select id="to_value">
<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="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
</select>
JS
$("#from_value").change(function () {
var val = +this.value;
$("#to_value option").hide();
$("#to_value option:gt(" + val + "),#to_value option:eq(" + val + ")").show();
$("#to_value").val(val);
});
DEMO
Hope you are getting value in from_value.
Then you could try this
$("#from_value").change(function() {
var from_value = $("#from_value").val();
var opts = '';
for(var i = from_value; from_value <=10; i++)
{
opts = opts+'<option>' + i + '</option>';
}
$("div.to_value").html('<label>To Value</label><select name="to_value" id="to_value">' + opts + '</select>');
});
I have select boxes, I would like to hide (delete) items from options that are already selected:
<select name="gets" class="gets">
<option value="0">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>
</select>
<select name="gets" class="gets">
<option value="0">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>
</select>
<select name="gets" class="gets">
<option value="0">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>
</select>
<select name="gets" class="gets">
<option value="0">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>
</select>
So if I choosed option 1 from 1st select box, it should disappear from the rest, if I choose option 3 on select box 4, it should disappear from the rest
Thanks in advance
Say like below:
$('.gets').change(function(){
var value = $(this).val();
$('.gets').not(this).find('option[value="'+value+'"]').hide();
})
DEMO
If you want to exclude for SELECT option say like below
$('.gets').change(function(){
var value = $(this).val();
if(value!=0)
$('.gets').not(this).find('option[value="'+value+'"]').hide();
})
You'll need to find all the options with the same value in the other select's and hide them.
I would use something like this:
var selects = $('select');
selects.bind('change', function(e) {
var val = this.value;
//show all options
selects.find('option').show();
selects.each(function() {
if(!this.value) return;
//hide the selected value in the other selects
selects.find('option[value="' + this.value + '"]')
.filter(':not(:checked)')
.filter(':not([value="0"])')
.hide();
});
});
Example
You can try this:
$("select").on("change", function(){
var selectVal = $(this).val();
$("select").not($(this)).find("option[value="+ selectVal +"]").remove();
});

This is a weird one but our developer is away and my client is having a web site presentation tomorrow.
On a web page one drop-down has the values below. Is there a way using script/css our designer can hide the replicated values and just show 1-9 once? Thanks so much.
<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="8">8</option>
<option value="9">9</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="8">8</option>
<option value="9">9</option>
Try this:
var usedNames = {};
$("select > option").each(function () {
if(usedNames[this.text]) {
$(this).remove();
} else {
usedNames[this.text] = this.value;
}});
Working Demo
you can remove the dups using jQuery like below:
var found = [];
$("select option").each(function() {
if($.inArray(this.value, found) != -1) $(this).remove();
found.push(this.value);
});
Keep an array of found values, if value not found in array, add it .push(), if found, its a dupe, .remove() it.
You can use :gt() selector:
$('select option:gt(8)').hide();
try this ....
$('select option').each(function(i)){
if(i >= 9)
$(this).remove();
});
i have a select option which works fine,but what i want is if more than one is selected then 10 % discount has to be added, how can this be done
and on selected the value multiplies in Java script
//javascript
function totprice(f,n,amt)
{
var tot=0;
document.getElementById('lbl_tot'+n).value=amt*f;
for (var k=1; k<=document.getElementById('rowcnt').value; k++)
{
if(document.getElementById('lbl_tot'+k))
{
tot=parseInt(tot) + parseInt(document.getElementById('lbl_tot'+k).value);
}
}
document.getElementById('txttot').value=tot;
document.getElementById('txttotprice').value=tot;
}
HTML
<select name="amt" id="amt" onchange="return totprice(this.value,2,110);">
<option value="0">0</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="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
<option value="13">13</option>
<option value="14">14</option>
<option value="15">15</option>
<option value="16">16</option>
<option value="17">17</option>
<option value="18">18</option>
</select>
Your select tag should be
<select name="amt" id="amt" onchange="return totprice(this.value,2,110);" multiple>
To make it multi select. Now when user will select multiple options (using Shift+click) then in your JavaScript function get these values and do the processing (provide discount/ any logic)
Updated
You wish to multiply the value the user has selected with the discount amount (110)
In your JS have this
var x = parseInt(f)*parseInt(amt);
If f = 2 and amt = 110 then x = 220. You need to do parseInt(value, radix) by default radix is 10
EXAMPLE:
var optionSelected = document.getElementById('amt').value; //optionSelected is nothing but this.value
if(optionSelected > 1)
{
//Offer discount
var x = parseInt(f)*parseInt(amt); //where f and amt is passed through function call
}
else
{
// Do nothing/ other logic
}
Hope this helps!!
