I have a select dropdown:
<select onChange={(e)=> console.log(e.target.id)} id="cars" name="carlist" form="carform" >
<option id="a" value="volvo">
Volvo
</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
I would like to get the ID a when selecting 'volvo' from the dropdown, thus getting the ID of the option, how can I achieve this?
The reason why I'm trying to get an id is because this dropdown can have multiply options with the same name (they would be separated by a line)
Use the selectedIndex to get this.
var getId = document.querySelector('#cars');
console.log(getId.options[getId.selectedIndex].id);
You can have the pass the reference of 'this' and get it from there.
something like the below answer

I'm working on my MVC project and need to bind selected value with textbox - what I mean is when you choose an item on a selected list then this value appears in a text box. Here is an example:
<div class="row">
<select id="chasis" name="type">
<option value="sedan">sedan</option>
<option selected value="hatchaback">hatchback</option>
<option value="cabrio">cabrio</option>
<option value="coupe">coupe</option>
</select>
</div>
<label>Your choice is: <input id="chasisText" type="text" value=""></label>
and jQuery code:
<script>
$(function() {
$("select#chasis").change(function(e){
$("#chasisText").val(e.target.value);
});
});
</script>
This code works well but my question is if there is any other way to show selected value in a textbox? Maybe easier or more tricky?
add jquery cdn to head part of your HTML if you havent added, ignore if already added.
add chasisChange function to select
<select id="chasis" onchange="chasisChange()" name="type">
below Jquery function (chasisChange()) will be executed when value changes of select portion of HTML.
function chasisChange(){
var val = $('#chasis').val();
console.log(val);
$('#chasisText').val(val);
}
working example

Is it possible to use jquery to filter select options to only show options with a certain value?
Say I had this:
var testArray = ["foo", "bar"];
<select id="dropdown">
<option>bar</option>
<option>baz</option>
<option>foo</option>
</select>
After my script executes, I'd like to be left with the following:
<select id="dropdown">
<option>bar</option>
<option>foo</option>
</select>
You can select all elements which are not in your array using .not() and $.inArray(), and then remove them using .remove().
See example below:
var testArray = ["foo", "bar"];
$("#dropdown option").not(function() {
return $.inArray($(this).val(), testArray) > -1;
}).remove();
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="dropdown">
<option>bar</option>
<option>baz</option>
<option>foo</option>
</select>

how to include write-in option after drop-down option in html or javascript. As an example in the coding below,
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="vw">VW</option>
<option value="audi" selected>Audi</option>
</select>
But the user's choice wasn't in the list given (e.g. Honda). so he/she can write their option in 'others' option.
Apologies for my english. Thanks in advance.
It seems you may want to use the <datalist> along with an <input>, which offers the functionality you're looking for; in the below example if the user types S then the option of Saab will show up which can be selected, or the user can continue to type to add a new option to the list:
<datalist id="carOptions">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="vw">VW</option>
<option value="audi" selected>Audi</option>
</datalist>
<input type="text" name="automaker" list="carOptions" />
While this may not be precisely what you're hoping for it does offer the functionality you require without a dependence on JavaScript.
References:
* <datalist>.
* HTMLDataListElement.
You can easily do that with jquery.
$('#dropdownId').append($('<option>', {
value: -1,
text: 'None of them work for me..'
}));
And just handle the case when the value is -1

I have a select item with in there a few options, and one of them is called "other..". What I want is that when a user clicks on "other.." a textarea will appear, I know this can be done with jQuery. Here is a short and simple version of my HTML:
<html>
<body>
<select>
<option value="opt1">Option 1</option>
<option value="opt2">Option 2</option>
<option value="opt3">Option 3</option>
<option value="opt4">Option 4</option>
<option value="other">Other..</option>
</select>
<input type="text" id="other_text" />
</body>
</html>
Add the change event to your dropdown list, which will toggle the text field if the selected value is "other":
$('select').on('change', function() {
$('#other_text').toggle(this.value === 'other');
});
