I'd like to remove the first option of an select tag when I click on the select tag. Is this possible?
I don't want to see the first option after that click.
Thanks for any help.
You can remove the first option on click with jQuery.
$(document).on('click', 'select', function() {
$(this).find('option').get(0).remove();
});
This simply removes the first option of a select tag on click. You need to add an if statement to check if it was already removed.
There's also a simple no-javascript solution:
<select>
<option style="display: none">--Choose--</option>
<option>Cheese Cake</option>
<option>Hot Pockets</option>
<option>Sausage</option>
<option>Cookies</option>
<option>Bacon</option>
</select>
(Copied from the comments from #chipChocolate.py)
If you use bootstrap add placeholder attribute in your select.
If your not
<select required>
<option value="" disabled selected>Select your option</option>
<option value="1">1</option>
</select>
// to remove first...
document.getElementById("element_id_str").options[0].remove();
//to remove the lot...
document.getElementById("element_id_str").options.length = 0;
<select required>
<option value="" disabled selected hidden>Select your option</option>
<option value="1">1</option>
</select>
Probably you just want this:
<select required>
<option value="" hidden>Select your option</option>
<option value="1">1</option>
</select>
A very naive way of doing this:
$("#selector").change(function(evt) { //listen to changes of selection
var theElement = $(this);
if (!theElement.data("selected")) { //check if flag is not set
theElement.children("option")[0].remove(); //remove 1st child
theElement.data("selected", true); //set flag, so it doesn't continue removing items for every change
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="selector">
<option>--Choose--</option>
<option>Apple</option>
<option>Banana</option>
<option>Papaya</option>
</select>
If you want to remove the first option use this
$(document).ready(function()
{
$("select").children().first().remove();
});
If you want to remove the first option after clicking on the select box use this
$(document).ready(function()
{
var removed=false;
$(document).on("click","select",function()
{
if(!removed)
{
$(this).children().first().remove();
removed=true;
}
});
});
Javascript:
document.getElementById("SelectId")[0].remove();
Get the first option in the select and remove it.
I had the same problem, but the solutions above just work with one form, not with many. I added some extra code in order to validate it for many in your form:
$(document).ready(function()
{
$(document).on("change","select",function()
{
var x = $(this).children().first().attr("name");
var n = x.localeCompare("todelete");
if (n == 0)
$(this).children().first().remove();
});
});
Where "todelete" is the name for all first elements [0] defined inside the
Please select value //all first elem must have the same name
"> //the others another name (can be the same BUT not "todelete")
You need the id or class to remove the item. While testing and debugging I found 'option:first' fails to remove the item. But 'option:first-of-type' always does the work. You can get more info about 'first-of-type' here :first-of-type
$("#ID_or_.CLASS option:first-of-type").remove();

I'm trying to add the options selected from one select element into another. I'm guessing it'll be something like this.
var selected = $("#selectWithOptions").append("<option'>" +
options[selectedIndex].value + "</option>");
This does not work.
The logic is pretty straight-forward and you can follow the inline comments in the JS function:
// Fire this function when a dropdown item is selected
$('#dd1').change(function() {
// Grab the text of the selected item
var selectedOption = $('#dd1 :selected').text();
// If it is not already in the second dropdown list, then append it
if( $('#dd2 option').filter(function () { return $(this).text() == selectedOption; }).length <= 0 ) {
$('#dd2').append('<option>'+selectedOption);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>Dropdown 1:
<select id="dd1">
<option selected disabled>Select option</option>
<option>foo</option>
<option>bar</option>
<option>baz</option>
<option>xiyar</option>
</select>
</div>
<div>Dropdown 2:
<select id="dd2">
</select>
</div>
In Javascript(and jQuery), everything is an object. Get the selected option elements using the jquery :selected selector and then append them to the second select element.
I'm using clone() but if you don't want to copy, rather you want to move the elements from one select to the other, then get rid of clone() and that same object will be moved to the other select element.
$('button').on('click',function(e){
var opt = $('#first option:selected').clone();
$('#second').append(opt);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="first">
<option value="hello">Hello</option>
<option value="world">World</option>
</select>
<select id="second">
</select>
<button>
Copy
</button>
In my database there's a column, name is Sequence & it consist of numbers(int). In my application's edit function I need to show that selected number in my jQuery dropdown list.
In my AJAX call I sent ProductId and get the specific row.
Html Control
<select class="form-control" id="drpsequence"></select>
My jQuery dropdown
$("#drpsequence option:selected").append($("<option></option>").val(msg._prodlng[0].Sequence).text(msg._prodlng[0].Sequence));
In the above code msg._prodlng[0].Sequence comes as selected number
I'm not sure what you are trying to do but it looks like you are adding an <option> tag into another <option> tag which is most likely not what you want.
If the returned value already exists as a selected option:
$("#drpsequence").val(msg._prodlng[0].Sequence).prop('selected', true);
Or, if you need to add an option:
var opt = $("<option>")
.val(msg._prodlng[0].Sequence)
.text(msg._prodlng[0].Sequence);
$("#drpsequence").append(opt);
Snippet example:
// foo --> select
$('#foo').val('baz').prop('selected', true);
$('#bim').click(function(){
$('#foo').append('<option id="boop" value="boop">boop</option>'); //<-- or loaded value
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="foo">
<option>-- select --</option>
<option id="bar" value="bar">bar</option>
<option id="baz" value="baz">baz</option>
</select>
<button id="bim">Add an option</button>
You need to do one of following.
Either find that option and make that selected = true like this.
$("#sel option").each(function(i) {
if ($(this).val() == "Orange") $(this).attr("selected", "true");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="sel">
<option>Apple</option>
<option>Orange</option>
<option>Banana</option>
</select>
Or if that option is not found then add and make that selected = true.
Like the one, which you had in your question.
i want to clear only 3 elements in dropdown list. how to do by iteration i.e indexbased would be fine.
Here is how my dropdown looks.
<div id = "Dropdown">
<select id="dropdownlist" class="trace dropdown" name="dropdownlistitems">
<option value="ID1" selected="selected">--Please Select--</option>
<option value="ID2">ID2text</option>
<option value="ID3">ID3text</option>
</select>
</div>
Do you mean something like this?
$('#dropdownlist option').each(function (index, option) {
if(index!=0)
{
$(this).remove();
}
});
This will remove each option tag that the loop iterates through (except, of course, the first one)
How about this?
$('#dropdownlist option:lt(3)').remove();
This selects the first 3 options and removes them.
I have the dropdown below. I want to populate orange in the dropdown when the page loads. I made a function, PopulateDropDown, which runs the jQuery code to do so, but it is not working.
<select name="cboFruits" id="cboFruits">
<option value="Apple">Apple</option>
<option value="Orange">Orange</option>
<option value="Mango">Mango</option>
<option value="Banana">Banana</option>
<option value="Pine">Pine</option>
</select>
<script type="text/javascript" src ="jquery.js"></script>
<script>
function PopulateDropDown(pFruitName)
{
$('cboFruits :selected').val(pFruitName);
}
$(document).ready(function(){
PopulateDropDown('Orange');
});
</script>
Well, there are a few problems with your code:
$('cboFruits :selected').val(pFruitName);
First of all, you're missing the # in front of cboFruits, since cboFruits is the ID property of your select list.
Also the correct way of setting the selected option would be something like this:
function PopulateDropDown(pFruitName)
{
$('#cboFruits option:contains("'+pFruitName+'")').prop('selected', true);
}
$(document).ready(function(){
PopulateDropDown('Orange');
});
Ref this question How do you select a particular option in a SELECT element in jQuery?
You forgot to write ** # ** and remove selected
$('#cboFruits').val(pFruitName);
EDIT :
or you use
<option value="Orange" selected="true">Orange</option>
when page by default 'Orange' will be selected
It should work:
function PopulateDropDown(pFruitName)
{
$('#cboFruits').val(pFruitName);
}
i have a form that has select element
<select name="adddisplaypage[]" id="adddisplaypage" multiple="multiple">
<option value="all" label="all">all</option>
<option value="index" label="index">index</option>
<option value="tour" label="tour">tour</option>
<option value="aboutus" label="about us">about us</option>
<option value="contactus" label="contact us">contact us</option>
<option value="destination" label="destination">destination</option>
<option value="reservation" label="reservation">reservation</option>
</select>
can anyone help me to select this option (multiple select) on click i.e the option gets selected when clicked, and deselected if selected on click.
I realized I may have misunderstood your question. Something like the following should work, though I'm not sure about browser support:
$('#adddisplaypage option').click(function(e) {
e.preventDefault();
var self = $(this);
if(self.attr('selected') == '') {
self.attr('selected', 'selected');
} else {
self.attr('selected', '');
}
});
In your click() handler, you could write something like:
$("#adddisplaypage").val("index");
That should select "index", for example.
You can pass an array to the .val() method. For instance:
$('#adddisplaypage').val(['index', 'tour']);
